I'm glad you pointed out the efficiency loss, well researched video, that was really hard to find when I was doing research on these hubs too & probably not a frequently asked question. :)
I have a ebike with enviolo automatiq. I absolutely love it. No hassle of even thinking gears forget about changing them. Gates belt drive is no maintenance. Only cons are bit heavy, little drag but no issue for ebikes.
They also work amazingly well on tandems since you dont have to agree with the passenger on a time to shift. Just twist the grip and the change is felt no problem. Huge uprade to tandem riding!
We appreciated that too (although for big shifts still had to back off the power).........but found that when using low gears to go up hills, with two people, we were often over the level of torque that it seemed to be comfortable with......I would describe it as feeling 'squishy' when pedalling very hard
As someone who used a NuVinci N360(Enviolo before 2017) for Mountain biking for 2 years, I can tell you outright that the efficiency loss of bike CVTs absolutely destroys you on steep climbs. I ended up going from the N360 to the Rohloff speedhub and the speed difference was insane. My best time in ideal conditions on specific 10 mile MTB trail was 1 hour and 20 minutes with the N360, I was able to do the same trail in 58 minutes on the rohloff my very first time out in sub-optimal wet/muddy conditions. The Efficiency makes an Insane difference over time and distance especially if you have any steep climbs with bumps like roots or rocks on them. Granted if you're using the CVT on an E-Bike with pedal assist on, then the difference probably wont matter to you, but otherwise; you're gonna have a bad time over distance especially if there are any steep uphill sections.
Premium Efficiency example (Higher cost equals better performance & efficiency) Superlative air-source mini-split heat pumps with COP of 7.1 cost 3X more than cheaper units with a COP of 3.4 Long range BEV's cost 2X more than ICE with similar range per fueling LED bulbs with the same spectral performance (color matched, wide color gamut and high CRI) about 10x more costly Homes with superior German Passivhaus super insulated and high efficiency heating & cooling are 2.5X more costly Aircraft with better fuel economy can cost 40% more in capital cost upfront I.E. You can't get something for nothing in engineering, or there is no free lunch in physics Ultra low energy consumption homes with full function cost 5-8X more than cheaper less efficient simple homes- this is called the dark side of going green because making all that super efficient all copper or silver heat exchangers, gold wires, and titanium foam + MLI insulation, gap sealing, thermal bridge mitigation, low-E triple glazed windows, high R-factor fireproof security doors, AI control of systems and smart home devices, more wires, more networking, specialized expensive heat pumps fridges, clothing driers, water heaters, and heat pumps for HVAC.
Premium capital cost for super efficient systems and devices has a better ROI when they are used in economies where energy for those systems more costly. Like in Tokyo where electricity cost $1/ kWh an LED bulb has a much faster ROI than in Grant County, Washington State where electricity only $0.03/kWh or 33X less expensive, where an LED bulb almost does not pay for itself before flickering failure or burning out. Also given the complex manufacturing of LED chips on legacy node IC manufacturing equipment, there are hidden toxic environmental effects from the emissions of said processes, that were never an issue with incandescent, low and high pressure sodium, halogen and fluorescent bulbs which also saw a 50x reduction in mercury content per bulb, important cause Hg now more expensive that Ag or liquid metal mercury costs more than silver now.
I have changed my 3 1990 steel Moser road bikes from 3 x 8 derailleur to Shimano Alfine 11 with DI2 changers. I am delighted with the results and would not go back. The lowest gear was a problem but from your previous videos chanced a 1.0 to 1.6 sprocket to chain-ring ration, based in my weight, giving a bottom gear of approx 21" and after 6 months there have been no problems. Found your information videos very helpfull.
I was overwhelmed but in a concise manner, I now can scrutinize my new purchases with your channel’s informing videos, outstanding you now have a new subscriber..
About the stiff shifter: There is two shifting available: single turn, and double turn. The first one is stiff but you can go thru the whole range in one turn. On the other hand, the dual turn is much softer but you have to turn it more.
I think what is more important when comparing efficiencies of gear hubs vs derailleur shifting is the FEEL when pedalling under load. Obviously when simply commuting it is not going to bother anyone that much, but the longer your ride is the more frustrating it gets in my opinion. I couldn't care less about the extra 2 minutes on a 100km ride, but that feeling of each pedal stroke dissipating somewhere in the system finally got me. I know I'm exaggerating, but it felt like jogging on a beach vs jogging on asphalt, especially in lower 'gears' climbing uphill. I was nevertheless happy after I finished a Maratona d'les Dolomites (160km, 4000hm) on my modified BMC alpenchallenge with nuvinci 380 and gates belt drive 😅 Fine-tuning the gear ratio to find the best cadence for every specific moment is something magical and it is such a huge difference even compared to derailleur gear jumps. And I'm not even talking about rohloff with its 14% chasms between each gear. For everyone to understand - I'm mostly bikepacking on a road bike, so for me the optimal cadence/speed is important. And I do not mean always staying in 90rpm zone - depending on terrain/fatigue you would prefer doing 60rpm or 110rpm instead of the 'optimal' 90. I also had a bike with pinion 1.18 for some time. Much better feel in terms of efficiency... And oh that amazingly light rear end 😊. But i was literally appalled by not being able to shift under load at all. I know all gear hubs have this problem, and even derailleur shifters can give up in certain situations, but pinion was the worst I've ever experienced when trying to shift to a lighter gear on a 15% climb. So after a couple of years of experimenting I'm back to derailleurs and chains 😐
Thanks for all the advice, and for confirming what I’d suspected- that the local bike shop everyone else raves about has been trying to sell me very expensive stuff which won’t fulfill my needs! Mind you the dead giveaway was that whenever I asked some sensible questions and pointed out why something would be an issue for me they snapped at me, and made outrageous claims like “whenever there’s a fault it’s because the customer did something stupid” (for landing in a river,) and “our wheels don’t break” (neither did mine until I was hit by a car- that’ll break anything.)
you are forgetting the part where only a new and properly lubricated chain setup running the chain straight is more efficient than a belt. once you ride in a gear where the chain can not be straight anymore you are losing power, chain slightly stretched ? loosing power again, chain not completely clean and well lubricated ? loosing power again. the belt on the other hand doesnt have these problems.
@@Pixelplanet5 well then I guess I'm always riding properly lubricated new chains in the right gear :D ok jokes aside, I am not talking about efficiency numbers in relation to an absolute efficiency. I'm talking about the feel. Grinding up a hill out of the saddle with nuvinci felt like treading on something soft when compared to doing it on a granny gear with an imperfect chain line. You'll know what I mean if you ride around on nuvinci like I did for some time. Again not saying that the hub has no place in the cycling world - it does. Just not for me for the reasons stated above
@@Pixelplanet5 oh now I see that you only talk about belt vs chain. Ok then I can't disagree. My problem is not the belt though but the gear hub. I did not say that a belt drive is less efficient than a chain
As a road cyclist who occasionally uses these hubs when using bike shares, my biggest annoyance is the massive range in the highest ratios (which i basically always am in with these because they are geared so low for the average cyclist) this is definitely due to wear somewhere in the system, because when they add new bikes to the fleet they always have good ratios at first. Perhaps it is due to the cables or misuse/lack of maintenance, but with a bike fleet that is something you need to design for.
Came here to say this. Where i live (switzerland) there are a lot of hills, so theres a lot of shifting under heavy load going on. I very rarely see an enviolo over 10000km which still provides the full range. As far as i know the problem is the disc which angles the balls in the hub, it wears out and is no longer able to maintain the balls at the maximum angle
20,000 km is already not very long for a bike transmission to last, especially not for the price. And it sounds like it doesn't even really last half that. It's a shame, because it otherwise seems like a good idea.
Yeah I think at max gear and higher power on a public bike you're also more likely to run into problems. My local ones skip to hell and back if you try and push high torque through them with lower cadence (I'm an extremely casual cyclist, might be missing something)
Recently got a nexus 8 bike after a long stint of single speed. I love the low maintenance of IGH and it's great to see another video on a lesser known one. Keep up the great content, we love it.
I thrashed two Nexus 8 sport over a year of usage and maybe 6k kilometers. After switching to an Alfine 8, the known weather seal weakness of the Nexus has finally stopped harassing me
@@PhilosoFox When was that please? I think Nexus and Alfine had issues, that were resolved around 2017 or so. Asking because I have a new bike with Nexus 8, am planning a lot of sporty riding with it
No one does equipment deep-dives like you, they themselves send you on a ride for 20+ minutes not including the rewatch value :P Also you encouraged me to go on my first bikepacking tour, so huge thanks for your contribution to the community :) That being said, I traveled through Germany and France (parts on the European Divide Trail) on my Cube Travel Pro with a Shimano Nexus 8 Gear hub. While I had the time of my life and am hooked, I will never again bikepack on a hub with 308% gear range and 28" gear inches. Any hill with more than 3% gradiant was a major pain and required brutal pedaling (best I managed to climb was 9%). But most importantly the high gear jumps broke me. Not being able to find the right cadence turned out to be way more of an issue than I could have imagined. So even on flats I was constantly deciding between putting more effort into my strokes or fall back in speed considerably (losing momentum as well which only worsened my pace more). The Enviolo seems really promising, if only they offered ~530% gear range, I'd be sold. Now I'm banking on either getting a used Rohloff (insane value on 2nd hand market in Germany, usually 400€-800€) or getting a MTB with a 2x11 drivetrain (maybe you can guess where I got the idea from)
I have been bike packing with a derailleur system, got an Alfine 8 and own a Rohloff now. By far the best shifting system I've ever had! It's so smooth, and with the range I can easily pedal 12% gradients. I was lucky finding a second hand Rohloff first, then built a bike around it :). Highly recommended!
We have 3 bikes with enviolo at my house. One of them is automatic and that is just the best. Wife preferred enviolo to rholloff so we got a tern gsd with it. She just didn't like pushing the shifter all the time as well as the noise. So far several thousand miles in on the 3 bikes and still living the enviolo. It's just so easy to use since I never have to remember to maintain it and get in the proper gear. Though I really did like the rholloff hub.
The noise bothers her? Get used to it, understand that it is not equal to drag, and after some thousands of kilometres of use, and 2-3 oil changes, the noise diminishes greatly. My Rohloff has done almost 70,000km and I barely notice any noise when riding.
@@petesig93It seems like she's happy with the enviolo, so why would she want to "get used to it"? I'm sure it's a minor complaint, but it makes the ride a little less pleasant and not everyone needs a high performance drivetrain. Especially when there are no oil changed to be performed for the life of the hub.
I worked in a company designing and building bikes for food delivery businesses and we used Enviolo hubs in them. They work pretty well under those conditions and if the survive non stop rough treatment by under payed delivery drivers well enough they should do well for commuting and so on as well. We also paired them with 70 Nm mid motors and even that did not harm them long term (for granted, I left after about six months, but in those six months they done about 200 km daily every day between three shifts, so I would say that is a long enough span to judge on given the sample size of about 80 bikes)
Super helpful video Alee! This has really helped me to assess the merits of thes different hubs! Currently really enjoying a Nexus 8 with gates but I have always been intrigued by the CVT hubs. It might have been cool to mention that Leonardo Da Vinci invented the first one in wooden mock up form! Your information on the gear ranges was particularly helpful!! I did not realize how limited the Enviolo hub could be compared to a Rohloff! Super information with amazing clarity. Thank you.
I love your videos. I'm a road cyclist, and I've never done any bikepacking or bike trekking However I'm also a big technical guy so your videos are so satisfying to me
I personally have the pinion , rohloff , kindernay and Alfine 8. Love how robust the pinion and rohloff are. But my Alfine lasted me 6 months. Water seem to sip through and caused a lot of rust within the hub and the bearing race were so badly rusted the entire hub ceased. While the kindernay often have shifting issues and requires bleeding so very often.
Sturmey Archer and Shimano planetary hubs have very poor sealing against water invasion. If you look at a 3 speed Shimano or Sturmey hub you can actually see one of the 3 bearing sets, they are not even covered, much less sealed. Which leads to the second issue, they are packed with grease at the factory, so you can't lubricate them, without disassembling the hub, and repacking, which is beyond the abilities of even experienced home mechanics.
@@PRH123 i have disassembled my alfine 8 and its do-able . but requires the TL7001 shimano tool to align everything back in place when assembling back . but still , using sealed bearings would be so much better. on a side note the alfine 11 / di2 are using oil bath instead of grease. they work alot better and also lesser resistance than the alfine 8 .
@@IvanLiew1404 yes oil bath is much better…. the very old SA 3 speed hubs were oil lubricated, with a fitting on the hub for adding oil…. They need to bring that back…. or transition to cartridge bearings, as they have on their other hubs…
Living off a bicycle for years now, I can not say enough good things about Rohloff: no more cassette to clean or buy, less chains to buy, no more derailleur frozen in position, can shift whenever as much as I need. Love this product. Got a Schlumpf drive on the front, love it too.
There is just 2 bad things with Rohloff. Some sample variations. They do have some monday morning hubs with issues.(Rare) The actual list price. If you own a good one though. Your set for a lot of miles of near hassle free riding. They do have the best product.
@@1barnet1 I was grinding through more than 120 dollars (low side) per month (rear cassette, chains, front cassette). Not to mention days, where I couldn't shift. Imagine that. You are riding about 80 miles today and your gear shall be frozen in place 3 days ago. At this point tye Rohloff hub has been a great financial choice. The question is simple. How many miles are you going to ride. I live off my bicycle. Love their product. Change th oil twice a year. Replaced a paper gasket once. The oil is biodegradable. What's not to love about the price? Keep riding. Hope your having a great week. Know your/you're love
What were you doing to your bikes? I haven't changed a single part on my Mtb, and it's a 2012. Sure I've replaced chains when they are due, but never cassettes and such.
Great comparison. I own derailleur, enviolo and Rohhloff bikes. The derailleur bike is a folder and the only one I would like to drive should the battery die. The enviolo bike is the best to use in the city, mostly because the shifting is much less of a trouble at traffic lights or when conditions change quickly. For long distance biking I absolutely love my Rohhloff although I do not particularly like its electronic shifter.
I've been riding a Turi from Priority Bicycles that I bought 3 years ago and it has a 300% ratio Enviolo rear hub and uses a Gates Belt drive as well. I put 7000 miles on it before I replaced the front Cog because it was creaking: The belt had worn small cups on the torque side of its teeth. So I bought a new cog and while waiting for it to arrive I dusted the belt with CORN STARCH and the creaking went away! When the new cog arrived I replaced it and saw the old belt looked no different than the brand-new belt that I had been using as a spare and was in my road kit for 3 years. I put on the new cog and used the brand-new spare and kept the old belt for use as a spare, since 7000 miles hadn't harmed it. Seriously, it looked like it was new. My guess is these belts will last for 50,000 miles just like their big brothers that are inside many 4 cylinder car engines driving the camshaft. Enviolo makes one with a higher ratio but the 300% unit works fine for the city. Priority sold me a smaller rear cog that worked with the original belt because I wanted a "longer leg". I'm a huge fan of the Enviolo. I got a 600 recently for gravel and off-road use since the Turi is designed for sidewalks and paved roads. The 600 has a Pinon 12 speed crankset gearbox and is a great all around bike, but I still ride my Turi from time-to-time. I have nothing to say about efficiency as I'm sure it's not as efficient as a derailleur. But as far as joyriding and commuting, I wouldn't have a derailleur or anything with a chain anymore. I feel like an emancipated slave: I'm NEVER going back to those chains.
Laced in one on my 33 year old MTB. Love it. Would never go back to a derailleur. Have the manual shifter and have had no problems with it. I was glad to see that you saw/know that they can not shift between high and low without the wheel turning. Not a real problem; even when I come to a stop; as I've already downshifted. Love how if I want just a "bit" more/less peddle, I can give the knob a slight twist and I'm good. I started out with a 34/17 combo on the gears, but had no real low end, so I went to 24/17 and can pull hills with the best of them. I don't have a very high end, but I never go over 15 mph anyway. The 34 is still on the front so I can pull the derailleur arm forward and change rings if I'm on flat ground and want to go fast. I wanted to have just a plain chain, but I couldn't get the right spacing with the vertical dropouts. So I modified the old broken derailleur arm and I'm good to go.
I use the enviolo in a bike share more than daily. Everything you say is very true, when wet it's almost impossible to turn the manual gearchange (although if you grip differently can help), and even being constantly abused, it feels more like a cable issue than a gearbox issue. But they still get very beat up But being able to change gears while stationary is huge on cities with lots of red lights, worth the efficiency loss for me
In my personal view the only way to use a enviolo is with the automatiq only then the real advantages of the system become clear. The loss means its mostly useful for ebikes and yes the 10% extra loss (maybe as explained) is true but that just means you are one gen behind in battery tech. The jump from 500wh to 625wh or now 625wh to 750wh and 4 or 6 amps charging will take care of that. I ride about 60km a day on a reise and muller with enviolo automatiq changed my whole view on how comfy and fun riding can be that combined with our good and getting better bicycle paths in the netherlands.
@@ghagen888 Yes i now have 16000+ km on it. I have a nevo3 gt automatic with some changed parts. The only thing i didn't like where the breaks i upgraded them to the mdp models when it was time for some updates. Now the enviolo had to be replaced at 14000km not because it broke but during maintenance the shop made a mistake and broke it so they replaced the whole back wheel with a new one+enviolo+controller part. So i can't 100% say how long it would have lasted but it was fine as far as i can tell before they broke it :)
I use a alfine on my koga bike but a enviolo automatiq on my riese and muller doing about 10k on it over a year. I know you touched a little on this but for me the concept of bringing the whole drive train under software control is key. The cvt can always be kept in correct mode (less stress on parts) and combined with a (ebike) good motor and controller you can always 'shift' and change how the bicycle reacts. This makes for a whole different riding experience i don't shift at all anymore and the new bosch system also has a auto mode that adapts to you so even that doesn't need a change anymore. The end result is i just peddle and go always at my speed (turns out 68rpm) we are already seeing special modes where like in a car you can set it in different modes to create different riding curves and more sensors are coming in to control things like abs, wet riding, tilt sensors to it detects hills up and down. The fact that the whole motor and gear system is stepless and my 'peddling' can be stable but the drive train can be flexible is perfect. Its perfect for the dutch roads i use it on. The only downside if i move back to a normal bike (in this case my koga) i forget to shift all the time. I think anyone should ride a enviolo automatiq for say 100km just to see how it feels best on a comfy bike like a riese and muller its just so relaxing and fun.
Great video, you do a fantastic job of hitting all the good points and also the bad points of the enviolo hub. Some videos I’d seen prior to buying a bike with an enviolo hub gave me the impression that there are no disadvantages to this hub but that just isn’t the complete picture. One thing about difficult shifting and cable wear, I suspect the setup is poorly done, my bike had issues with difficult shifting and it took ages for me to diagnose it. If the cable lengths aren’t correct and the cable tensions are also wrong it’s very easy for the cable to run off its guide within the shifter. This can damage the cable as shown in your video or even damage the shifter itself (this happened to me…). There’s also a significant lack of literature on forums, UA-cam etc. The enviolo support videos are less than 5mins in length and do not show you where you can go wrong (again maintenance is not a perfect world except on cleanly edited UA-cam videos…). These hubs do have a place in biking but it’s not perfect by any means.
which hub do you recommend if you ride a bike a lot and need less maintenance? I currently have an Envilio 380 and I am thinking whether to change it to an Envilio automatic or a Rohloff automatic
@@mr.denoli7749 not having an electronic shifting enviolo or Rohloff it’s hard to say. Alfine di2 has complaints online as well. If you understand the setup for enviolo it should last (mine after heaps of stuffing about finally works fine and I understand what’s important when the tutorials tell you cable tension is important but without the explanation why and how much tension is required). I’ll keep using enviolo 360ct but I think if I could spend big rohloff would be in my sights. If I get off my ass I’ll make a video about all the issues I’ve had with enviolo 360
I bought a low-maintenance bike from a company called Priority, in New York. I love my Enviolo hub. The bike also has a belt drive, and the frame is made of aluminum to avoid rust.
@@buckroger6456 What someone needs to do is "fixed" gear cvt. Like in my polaris 1000c ATV. The speed spins the belt to higher gear. You can only do this with fixed gear as freewheel would drop you to smallest gear while coasting
You missed one thing about the weight difference. For normal cargo/components you are correct. But for rotational unsprung mass, these weight differences become much more impactful. If you're interested, there are a number of online calculators for that, and even if mostly aimed for cars, these can easily be used for bikes as well.
I decided not to place emphasis on unsprung mass as I don't think that full suspension bikes (and rough terrain) are the primary application of Enviolo hubs.
@@AndreSomersNot much because the mass is near the centre of rotation. It's the moment of inertia of the wheel that matters, not its mass, when it comes to the effect it has on the ride. Moment of inertia is proportional to mass but also to radius squared, so heavy rims or tyres make a massively bigger difference than heavy hubs.
Our customers like the Enviolo. But that depends heavily on the area of application. Here in Germany, the enviolo is finding more and more followers. I use the Rohloff. It's the ideal solution for those who don't know where to go. And I have to say I like the gears. I have the feeling that I never hit the right gear with the Enviolo. And as a touring cyclist, the Rohloff is of course better. But both have their pros and cons. As always a very good video. I like to show it to our customers if they can't decide. 😅
The negatives outweigh the positives for me on this one... The lack of climbing gear, fiddly wheel removal, unreliable shift cable.... This thing is not for long-distance tourers.
Exactly. Restricted pretty much to those who don’t ride much. Cool concept though. Maybe a ring to ball to ring to ball to ring design would add enough range? But that would reduce efficiency even further. And add weight and probably limit the torque even more. Oh well.
which hub do you recommend if you ride a bike a lot and need less maintenance? I currently have an Envilio 380 and I am thinking whether to change it to an Envilio automatic or a Rohloff automatic
The comparision is fair and done with a really comprehensive overview! In my =opinion= the Enviolo is only an option, when we are talking about E-Bikes. In this Application the lack of efficiency is less important, because you get the "dissipating power" from your electric motor. But it still "feels" a little "soft" while pedaling. But yes, the advantages are justifying the power that is lost in the hub: It is a good hub for everyday use, especially in combination with a belt drive and an automatic shifting, because you do not need to think about ist. It just works. On the other hand I have one Enviolo in my household that failed within less than a year (a "Heavy Duty" in a R&M Multicharger). The guarantee-handling was/is poor and so are the repair-options because there are simply none: You can just exchange the complete hub, that's it. The wear of the (inner) cables is also legendary, the 90° change of direction within the shifter is just poorly made. Another crazy thing is the "reset-problem" of the hub interface mentioned at 14:40. Why is it designed that way? But again: Even though I personally would prefer a Shimano over an Enviolo*, I recommend an Enviolo hub for Riders of E(!)-Bikes that don't want to think about shifting, maintenance and all the other things. *but I am riding only Rohloff 🙂
Great video and comparison. I chose the Enviolo for my first trike. Having a derailleur bent for an unknown reason on my main ride I decided to make the change on my future rigs. Rohloff was a choice but given the price and having electric assist, it would have been superfluous.
I'm amazed by the double standard. CVT is perfect because optimal pedalling efficiency is always achievable as long as you don't care about the overall efficiency. Derailleur is bad because you can never have optimal pedalling efficiency. Breaking news: if you don't care about everything else (your main argument for accepting the huge power loss of the CVT) you can also have constant perfect pedalling efficiency with a derailleur. If you feel like you are between 2 gears you can simply chill a bit and select the easier one. This sacrifices a tiny bit of speed (most often less than the 14% power you constantly sacrifice with a CVT). Instead of wasting those 14% energy from your last meal, you can use it to go further with a calm pace and without a sweat.
Very interested for use on my high wheel….probably have to build a new wheel for it..36” may be fit a front wheel , all depends on the axil I guess..dun-no?
Thanks for this detailed video. I'm very interested in CVTs. I first noticed them on your touring bike with the belt drive. I'm going to look into getting this kind of setup here in Japan.
5:10 that hit hard. my friend who has a lame right hand aked me to help build a geared bike that can be controlled by the left hand. i was stumped. lets not forget about left handers. honestly we need to ask for left and right hand gearing regardless of the system. but the button press gearing for be really god for someone like my friend. good point
The speed change happens because of the distance of the contact patch from the centerline of the axle in the ball. When the output contact is closer to the axle, the diameter of the contact path is smaller, so it's like having a smaller sprocket. When it is further from the ball axle, the diameter of the contact path is larger, like having a larger sprocket
I have one of these on my Tern GSD10. It's a pedelec, which means I can't really comment on efficiency. But it also isn't an issue. I really enjoy that I have full control over the gear I choose, and to be able to adjust at any time. I probably wouldn't choose this for a non-pedelec bike. For an ebike, it's perfect. Also, the Tern is ridiculously expensive (my wife pulled the trigger on that one), but I find normal bikes suboptimal by far now. It has excellent balance, excellent suspension, adequate pedelec support, and I can transport two relatively large kids and their school bags without even thinking about it.
Very interesting video. I have a Van Nicholas touring with an 18 speed Pinion gear box, and a Schindelhauer Heinrich with Bosch motor and Enviolo Automatiq. Where I live in western Massachusetts, it is pretty hilly and for day rides I get out on a good amount of gravel. The Van Nicholas is great for touring, but I find for daily use (errands around town or out for an afternoon ride) I turn increasingly to the Schindelhauer/Enviolo. In "Touring" mode I go up the 7%-8% grades around here, and it is so quiet and trouble-free. I thought I would miss the wider gear ratio of the Pinion but even with a bit of off-road the e-bike more than handles it. Service seems to be widely available and a local shop will handle the Bosch+Enviolo hub, a combo which has a reasonably wide distribution in the US. Love your Buyer's Guides, BTW.
In March 2011, I had a NuVinci N360 (Pre Enviolo) installed on my Rivendell Atlantis. It worked OK but shifting required some effort to twist. On mine, it would drift out of position (gear) at highest setting. If it would stay in gear I would have kept it longer. I sold it in 2016 as I was not riding it much. The pros and cons depicted on this video are consistent with my opinion. I would have loved electronic shifting.
I have experience with the rolhoff, enviolo and nexus 5spd e hub. All on urban arrow cargo bikes. I actually prefer the nexus over the enviolo but the rolhoff is crazy good! If I had to pick I'd be going nexus. They just work. The indexed twist shift isn't bad, feels similar to rolhoff for get up and go whereas the enviolo feels somewhat sluggish. Plus the cost of the nexus is hard to argue with!
Well, I can certainly appreciate the evolution of internal gear hubs. Now, my bike, an Apollo from 1962, is working on a three gear internal hub. It has done so since the day it left the factory. It hasn´t needed any oil change. It has always worked. It does not make any sound when I change gears or while driving. I can change gears while stopped (not recommended, as the third gear is quite strong to pull). I have the feeling that this is just another overengineering case, an illness our society is strongly suffering from. Again, I appreciate the idea and advantages, but normal people will never exceed the need for a lower first gear of mine, nor will they find third gear not enough for speeding. Combining bycicles with mobile phones on the other hand seems to me like getting crazy. We have now around 240 million cases of serious neck problems and that is only the tip of the iceberg. Mobile phones are the worst idea ever and people should start to STOP using them. As flexible I am with innovation, on that point I completely go the opposite and condemn them. I am now the only person in my city without a mobile phone, but some years from now, I will have been a pioneer instead of being laughed at. And yes, I am as old as my bycicle. In fact, we were "born" nearly the same day. This may explain some of my stupid texting, I hope. Kindest regards and the very best to you and your beloved. Miguel
I’d be interested in a comparison video between Rohloff and Pinion, as their ranges are more suited to my style of riding as I frequently ride up 17% inclines and my lowest gear on my Brompton is 28” from a 44T chainring and sometimes feel a lower gear would be preferable. Similarly, my MTB needs a wider range than Enviolo can offer.
On a 4.8 fatbike tire with some day bikepacking gear, I will ride up 18% grades fairly frequently. As a senior I find myself looking for even lower gearing and I do not like walking, lol! Who cares about the top gear, as I know how to still spin and tuck as I do not really care about lots of speed any more. :)
i watched one of your other videos and i left a comment.. i tested some enviola hubs and i liked them.. i also tested a shimano alfine and i didn't like how it shifted and how it clunked.. i would like to test a rohloff but i still think that i will like an enviola the most.. especially on an ebike..
Ease of maintainability is a big deal. The cost difference in servicing an Alfine 8 vs an Alfine 11 makes the Alfine 11 much cheaper in the long run even though the initial purchase cost is higher.
@@huhummmmmmm Did you perform the recommended yearly maintenance? Have you sent it to a bike shop to be looked at? It may need some tweaks to the barrel adjuster. Or it could be something else entirely.
I got it @ ebay for 180 american rubles 10 years ago with a warranty of 6000kms / 3 years and it's been 10 years ~20000kms and i feel like only the force required for rotating the actuator got increased, but still works fine. Maybe I'll have to change the wires but I want to upgrade to n380 with a belt. Absolutely recommend it. It's best thing that happened to my bike, as I wasn't feeling like to ride that long and were feeling tired due to shift ratio changes. Added note, automatic shift is not for hilltowns as the optimum rpm changes as the elevation climb rate changes. Better if they did it lighter instead of stronger. I mean, the design is strongest anyway, just a bit heavier than 1400$ rohloff.
After riding the auto shifting Enviolo (with Specialized interface) i did not want to go back to manual shifting of any kind. You can still adjust cadence on the fly.
My wife and own 4bikes with enviolo and we love the ease of shifting to keep the pressure off of your 70 year old knees 3 priority bikes and 1 Himiway electric bike
The beauty of bikes is you can have a 40 year old frame, just switch out a few worn parts and off you go. I actually like shifting. My car is manual shift also 😊
Thank you for explaining the Enviolo hub. Looks like a viable alternative for some riders. For your next tutorial on bicycle geared hubs, please consider doing one on the Kindernay.....Pros, cons and who might benefit from it's use. A similar formatting as this video would work well. One of the cons (in my mind) to the Kindernay is the hydraulic shifting. If they offered mechanical shifting as an option, I might give it more consideration. What is your take? Thanks for another in depth explanation of bicycle systems..........Be well.
Can't wait to get one of these on my gravel bike! I don't care about a little more "free resistance" or weight. I still want a loud freewheel so people hear me coming on bike paths though. ;)
Great insight, thanks. I was wondering how it worked. Can it work with a torque sensor? I think a 'continuum range' would be a better descriptive than 'infinite'. I've been wondering if a strain wave (or garmonious) gearing would work on a bike?
yes it does many brands (i use a Reise and Muller bike) use a combo of bosch midmotor (cx mostly) combined with the enviolo automatic. The enviolo can work by itself but some brands (bosch for example) have integrated it into their controllers so you can control the enviolo (see 'gear' and set peddle speed) on the kiox display and buttons near the grip. Not 100% sure what the integration does but to me the combined software (or under control of the bosch maybe) feels smoother than if the inviolo doesn't know anything and does it all by itself. Hope this makes sense the bosch system so the bike uses torque sensors, peddle speed and wheel rotation speed even if the enviolo doesn't directly use the torque sensor the whole bike does so create the best ride. I did 16000km on mine sofar.
@@scb2scb2 Man, I'm looking forward to be able to put some serious miles on the clock like that when I get an e-bike. I'm supposed to be choosing one, but actually just nerding out on the variations. I live in a very hilly city (Bristol), so that's probably gonna be the deciding factor in the end.
I love the feeling of riding Enviolo/ NuVinci Hubs but i'd prefer a broader gear range. I've never tried HarmoniQ or AutomatiQ but I'm stoked to do so. Thank you for the most detailed Tech Explanations on the best Bicycle Technologies
I hate to put a downer in internally geared hubs, but I spoke to a few bike shops in the past 18 months, and they all love them. They are apparently very smooth and easy to use. That said, they all commented that when they go wrong they are a complete pain to sort. I can only assume that here in the UK they are quite rare, and assuming rarer faults, means that mechanics really aren't familiar enough to be efficient are repairing them.
Why do we have to pedal at the same cadence all the time? Would it not be healthier to vary the cadence, pedal fast sometimes, pedal slow sometimes, pedal hard sometimes, pedal easy sometimes? My single-speed or three-speed is perfect for this. The belt drive is perfect. Why is it so difficult to find a bike with belt drive?
I have been using a SRAM AXS electronic shift system for two years. Last year on the North Cspe 4000 I a managed to get about 1m of water between the. Ottoman of the tyres and my backside in a flooded underpass I though had 1cm of water in it. And this year I did the European Divide Trail Adriatic to Baltic Off Road route (3000km) mud was in my teeth, hair, all my bags and I had to clean the bike off every 200m on one section of 4km. My point being the electronic shift has been a joy. There has been zero mechanicals caused by it. I suspect electronic shift will come to all gear change systems for all riders on all bike gear systems ( E bike or not ) in the next couple of years. Maybe in under 10 yrs it will be the default option on the just above lowest price and middling to high end bikes.
Love my Enviolo hub! Would definitely recommend for a daily ride/commuter! Toying with building a gravel bike with a Shimano hub and Di2 shifting one day though!
This is EXACTLY the type of video I was looking for. I've been contemplating the Priority Continuum Onyx with a CVT for a while now, but couldn't find any good direct comparisons between other hub shifters. It seems clear that CVTs are the way to go for low maintenance city riding. I saw at least a couple people mention that enviolo hubs have a break in period where the transmission feels sluggish brand new. Did you experience this yourself?
I have been riding a Priority Continuum Onyx with 380% Enviolo hub almost daily for over two years of city commuting in all sort of weather including rain and snow. The hub has been flawless. I did have to replace one shift cable recently. The cable problem was caused by one of the wires in one cable breaking at the rear wheel part. That broken wire then unwrapped itself from the rest of the cable, eventually propagating all the way up the cable to the shifter and then bunching up inside the shifter. I think the design of the little part the cable attaches to at the rear wheel is the problem. You're driving a screw down directly onto the cable to clamp it. Apply a little too much twist on the screwdriver and the screw can chew through the wires. It should have a clamp that is pushed down on the cable instead of directly smashing the cable with the screw.
Nice piece. Thank you. I find my NuVinci 380 a bit syrupy, especially when pedalling hard. If you're climbing a steep hill a fairly high cadence (75+) and low input torque seems better than vice versa. After all, you are squeezing a non-Newtonian fluid between two surfaces under very high contact pressure (at least that's how I assume it works). On the other hand, it does seem that on the flat, at least, the faster you pedal the more 'lossy' it is - which stands to reason I suppose. When the time comes I intend to do a bottom bracket ebike conversion. I think it will really come into its own then, even if it's not an auto.
I have been riding a four speed hub gear bike from time to time since 1970, the hub has a notably dreadful reputation but the steps are very nice plus for town use you never distracted with gear change because you can change gear when you like. I think I'd miss the steps, but on the otherhand, I also had an automatic CVT on my moped that was nice it went up ratios speeds with light loads and higher speeds and used a governor with ball bearing as the rotating weights.
As someone that tried the old auto-shift derailleurs bikes. It’s really not ideal especially if want to put any kind of power or going up a short steep climb. Maybe with electric assist and use of modern bike computers you can make it better or offer more control.
@@Cyclingabout I'm yet to find any other automatic shifting that is as good as mine. I use power data to adjust my cadence automatically rather than maintain a fixed cadence like other automatic shift systems.
I soured on enviolo after it failed on our Urban Arrow after only 3800 miles. They replaced it under warranty but it took quite a while to turn around.
i just got a qwic atlas vario, with the heavy enviolo and belt drive... biked 80k with the motor off, almost all the way, it was a pleasure even if its only 83 percent...
I tried it once - and I _hated_ it. I wanted to like it, really liking that the bike had a belt drive, liking the idea of a maintenance free drivetrain. And at the start of the ride, I liked it. Especially the possibility to change the gear ratio while standing was great! And for the first few minutes with several stops at the traffic lights, I enjoyed the ride. But then... It was an electric bike, and as soon as I was above the support threshold it was like pedaling through syrup. Especially going downhill was terrible, I never had to pedal _against_ a resistance downhill to keep my speed. I immediately returned it and chose another (conventional) drive.
My first experience of one of these was on an ebike, under the Nuvinci branding. With the 250w mid drive it was incredibly sluggish. My following experiences have also been with ebikes and again were incredibly sluggish. Nuvinci, or Enviolo refuse to publish the efficiency of their hubs, and they make a very large effort to convince people that third party testing shouldn't be trusted. They know these hubs aren't efficient but won't admit that, and they'll only get worse with age, not better. The twin cables also make puncture repairs very annoying. I absolutely hate these hubs, I hate the company, they're unbelievably heavy, and aftermarket support is very lacking in many parts of the world. I contacted them once about some bearing play from the shop I worked at, and the response was less than helpful, implying that replacing the hub at full price was the most convenient thing for them.
which hub do you recommend if you ride a bike a lot and need less maintenance? I currently have an Envilio 380 and I am thinking whether to change it to an Envilio automatic or a Rohloff automatic
Few points on Rohloff. Many owners say that gears 1-6 are basically never used. There are reports of oil leaks. Lastly, there are complaints about the noise in certain gears.
Depends on what you are using your bike for. On a city bike the 520% range is likely overkill. On an MTB it is not (I certainly use the lowest gears a lot). I never had any trouble with oil leaks but I can only speak for myself. And yeah, every gear has its own sound. Not a big deal IMHO.
The reports of oil leaks are largely exaggerated. It's pretty much the same few repeated again and again year after year, out of the many thousands of Rohloff hubs in use. I wouldn't worry about it (and I don't - my Rohloff doesn't leak). I use gears lower than 6th all the time, and I ride in a city. It's just a hilly city. Also, using lower gears up hills gets me longer battery range on my e-bike - rather than using max assist in a mid-gear, I can bump the assist down and use one of the lower gears. 3rd comes in to play regularly, and I've used 2nd on one particularly nasty hill. 1st is just fun every once in a while lol. But I use 4th often. And as for the noise, it ticks when coasting just like any derailleur-equipped bike. The nature of the ticking is different between the 1st-7th range and the 8th-14th range because of the reduction gear. But it is true that it is not silent like a Shimano 5-speed e-bike hub (I think it's called the Inter-5?) that I also have experience with, or an Enviolo, but I don't know why anyone would complain about normal bicycle gear sounds. The wind drowns it all out above 10 or 12 mph anyway. I'd recommend trying every gearing option before buying an expensive bike tho. Sounds that don't bother me may drive somebody else nuts, who knows, and be sure to go up a hill to be sure the lowest is low enough. I tried an Enviolo-equipped version of my bike before buying, and I really liked it. Very smooth, totally silent, decent range. I'd totally get one if I lived somewhere flatter. But the hills around here, many above 8%, some up to 15%, plus the relatively placid cadence of around 78rpm at max assist speed of 28mph/45kph in 14th, made me bite the bullet and shell out the wince-inducing extra chunk of money for the Rohloff. It hurt, I ain't gonna lie. But this was a long-term purchase and I'm glad I did. It's been brilliant.
If gears 1-6 are "never used," then the bike is obviously undergeared! Rohloff is the benchmark for IGH, and not by accident. Speedhub 500/14 has the most user friendly gear range, efficient power transfer, enviable reliability and after sales back up. I considered a Nu Vinci some years ago when they were available cheaply on eBay, but lack of gear range and sub 90% efficiency were deal breakers. I spent much more on a Rohloff and have never regretted it. Annual oil changes and one set of replacement cables is all it's needed over several years. Tough to beat on all counts.
I feel that the lack of low-end gears are the biggest issue for me with the Enviolo. There are plenty of urban areas with steep climbs (DC, San Fransisco, etc.) that just wouldn't be great to ride in with this hub, at least without electric assist. With a Rholoff, you can just downshift to the lowest gear and can climb it without even sweating.
Can’t you modify this by changing the bikes gear ratios? Of course, this would take some off of the top end. The 14% efficiency loss is my biggest concern. How could you stay with the group in a group ride unless your 14% stronger and in better shape than everyone else?
@danparish1344 It's not for group rides. It's for city travel. The ability to rapidly shift gears is great for cities since it's stop and go. As for switching gear ratios, it's the torque limits that make it an issue.
@@TheSJCieply I used the bikeshare in SF for many years and never had too much of a problem climbing. They get plenty low. I'm relatively fit though. But the CVT plus an ebike means anything in SF is climbable.
@@AJHillis Most of bikeshare bikes are climbable, but you'll get really sweaty going up the hills. If you have a well designed hub, you can just downshift to a low gear and ride up the hill at a gentle pace. There's a big difference between being able to climb a hill and being able to climb a hill comfortably while carrying a load of groceries, tired after a long day of work. For that you need a quality bottom end gearing.
i ride my non-electric bike with an enviolo on my 11+ mile DC commute every day. there may be places in the world where the climbing gear isn't low enough, but DC isn't one of them. i extremely rarely even use the lowest ratio.
I have been looking at ebikes and I think I want something like an enviola hub, electronic shifting, and chain drive. I would just be using it to ride around in Germany. It seems to be a good option.
15.32 Yikes! That looks a really dangerous place! I have had an N360 Nuvinci hub for years and concur with everything said here. Never had trouble with cables though. Great video 🙂
Eight months ago I got a Specialized Vado 5.0 IGH with the Enviolo AutomatiQ gear hub to replace a 2020 Specialized Como 4.0 with a derailleur. Both are e bikes, and I live in the mountains with a normal morning ride of 20 miles and 2,400 feet of elevation gain. The loss of efficiency on steep terrain with the Enviolo is dramatic and extremely disappointing. I went from a 500:watt battery to a 710 watt battery, looking forward to an increased range, and yet because of the decreased efficiency it has roughly the same range as the smaller battery. In order to climb the steep hills in my area, I need to increase my assistance level 1-2 levels (with only 3 levels available). The old Como feels like a race bike compared to the sluggish Vado. The Vado with the Gates carbon belt is much noisier than the Como with a chain (have no clue why?). My wife and I joined another couple on their new Specialized Como derailleur bikes for a 240 mile ride on the Katy Trail, averaging 40 miles per day. I am a much stronger rider than the others, but stayed in the back per wife orders. We all used the lowest level of assistance for the entire trip, and at the end of each day I would compare the stated range left on my Vado to the other couple’s Comos. They also had the same size battery as I did. They typically had 20-30 more miles of expected battery life than I had. According to the Specialized website, expected battery range was predicted to be identical between the IGH vs derailleur equipped bikes! Liars!!! And to think I paid $500 more to get a less efficient bike with less range and noisier to boot! What a sucker I was . . .
The main loss in these types of CVT or Variator as they are called in industry, is in the ball bearings that apply the load to one or other of the input or output. It would be wrong to think that the 'no contact' is unique to this drive, all rolling element Variators rely on this phenomenon as do ordinary ball and roller bearings, where in normal use the balls are not in contact with the races. It would also be wrong to believe that 'no contact'= no wear. All rolling element bearings suffer from extremely high near point contact forces leading inevitably to fatigue of the ball and the surfaces they run on. The well known Kopp Variator is very similar, just inside out with the idler being an external ring, this is not a new idea.
I would really like you to do a video on the best bikes (and ebikes), and gear hubs options for the steep hilly areas. I live in San Francisco and some of the hills in the city are 20-24% grade. I test rode the Enviolo and compared it to the 9-speed traditional derailleur did not really like the Enviolo. It has too much resistance and not very efficient. Perhaps the gear range is too short. The Rohloff is better but the bikes are too expensive.
Interesting! My car has an automatic CVT gearbox, I initially found it weird because the engine drones at the same pitch irrespective of the speed of the car. I guess that's because it's the ideal, most efficient RPM for the engine. I didn't know CVTs were available on bikes but it should offer the same advantage of a consistent cadence at any speed.
I guess it could be a regional thing then, here in Europe/just the Netherlands? After some digging it seems they’ve been pretty much phased out for a while now, although they never were rare quite to the level of just being in DAF cars.. thanks for the heads up, I now have some weird need to try a CVT equipped car some time.
@@FjodorvS I once owned a gen 5 Impreza and enjoyed the CVT very much. It was nice to cruise on a long flat highway and achieve 38mph, 2 over what the car was rated for. From 0-20mph it droned about 1200rpm then from 20-70 it gradually increases to 2000rpm. No shift lurches. You can really feel the efficiency over a regular automatic. And of course there's the ability to use the paddle shifters, drop down a few preprogrammed ratios, floor it at 6000rpm and feel like you're in a race car.
Love that "number nine" just like from Beatles' White Album Fun fact: this cvt is technically a planetary gearbox with gear teeth being surface roughness of discs and rollers. Not so fun correction for 21:55 - it changes the position of the contact patch, not size. But yeah, if you do the full rotation of the roller "sphere", you can say the ring area of all contacts is bigger or smaller.
Shimano 1x11 is simply the right combination, be it a hub or cassette. I don't ride much and continiously one type or another, always keeping all sorts of transmissions - always come back to XT 8000 or 700 Alfine.
@@feedbackzaloop I have a tandem, so I am stuck to the frame. Which means, in particular, that I have to stay with a gear that is "O.L.D. 135 mm" compatible. This excludes all new MTB/Gravel/Road groups. The CUES remains the only choice other than an IGH.
@@PrzemyslawSliwinski Pretty much all gears fit 135 spacing. Actually, it is up to the hub design, not cassette interface. And most used road/gravel 142mm standard is simply 135 with different endcaps. You can swap them and continue enjoying the simplisity of open dropouts. It is only the very new hangerless SRAM that requires a custom adapter.
Hi! Any reason to not have made a comparison with the Pinion drivetrain? It's known to be heavier and have a slight deficit of efficiency over the Rohloff...

@Cyclingabout pin this to the top so it doesn't get lost in the flood of comments on the video.
I'm glad you pointed out the efficiency loss, well researched video, that was really hard to find when I was doing research on these hubs too & probably not a frequently asked question. :)
Que bueno.seria traducir al español grcias
What should be the cost of 625% meshed IVT crank gearbox? In process of filing patents.
I have a ebike with enviolo automatiq. I absolutely love it. No hassle of even thinking gears forget about changing them. Gates belt drive is no maintenance. Only cons are bit heavy, little drag but no issue for ebikes.
They also work amazingly well on tandems since you dont have to agree with the passenger on a time to shift. Just twist the grip and the change is felt no problem. Huge uprade to tandem riding!
"dont have to agree with the passenger on a time to shift"
Ah, yes. The classical hostile-tandem-passanger situation 😅
We appreciated that too (although for big shifts still had to back off the power).........but found that when using low gears to go up hills, with two people, we were often over the level of torque that it seemed to be comfortable with......I would describe it as feeling 'squishy' when pedalling very hard
@@matmaxgedsyes that’s probably the loss of efficiency you’re feeling, they definitely don’t feel as solid as a regular cassette
The Automatiq would be even better on a tandem
Ok, that seems to be one of the only valid arguments for me. I feel that.
As someone who used a NuVinci N360(Enviolo before 2017) for Mountain biking for 2 years, I can tell you outright that the efficiency loss of bike CVTs absolutely destroys you on steep climbs. I ended up going from the N360 to the Rohloff speedhub and the speed difference was insane. My best time in ideal conditions on specific 10 mile MTB trail was 1 hour and 20 minutes with the N360, I was able to do the same trail in 58 minutes on the rohloff my very first time out in sub-optimal wet/muddy conditions.
The Efficiency makes an Insane difference over time and distance especially if you have any steep climbs with bumps like roots or rocks on them. Granted if you're using the CVT on an E-Bike with pedal assist on, then the difference probably wont matter to you, but otherwise; you're gonna have a bad time over distance especially if there are any steep uphill sections.
Premium Efficiency example (Higher cost equals better performance & efficiency)
Superlative air-source mini-split heat pumps with COP of 7.1 cost 3X more than cheaper units with a COP of 3.4
Long range BEV's cost 2X more than ICE with similar range per fueling
LED bulbs with the same spectral performance (color matched, wide color gamut and high CRI) about 10x more costly
Homes with superior German Passivhaus super insulated and high efficiency heating & cooling are 2.5X more costly
Aircraft with better fuel economy can cost 40% more in capital cost upfront
I.E. You can't get something for nothing in engineering, or there is no free lunch in physics
Ultra low energy consumption homes with full function cost 5-8X more than cheaper less efficient simple homes- this is called the dark side of going green because making all that super efficient all copper or silver heat exchangers, gold wires, and titanium foam + MLI insulation, gap sealing, thermal bridge mitigation, low-E triple glazed windows, high R-factor fireproof security doors, AI control of systems and smart home devices, more wires, more networking, specialized expensive heat pumps fridges, clothing driers, water heaters, and heat pumps for HVAC.
Premium capital cost for super efficient systems and devices has a better ROI when they are used in economies where energy for those systems more costly. Like in Tokyo where electricity cost $1/ kWh an LED bulb has a much faster ROI than in Grant County, Washington State where electricity only $0.03/kWh or 33X less expensive, where an LED bulb almost does not pay for itself before flickering failure or burning out. Also given the complex manufacturing of LED chips on legacy node IC manufacturing equipment, there are hidden toxic environmental effects from the emissions of said processes, that were never an issue with incandescent, low and high pressure sodium, halogen and fluorescent bulbs which also saw a 50x reduction in mercury content per bulb, important cause Hg now more expensive that Ag or liquid metal mercury costs more than silver now.
I have changed my 3 1990 steel Moser road bikes from 3 x 8 derailleur to Shimano Alfine 11 with DI2 changers. I am delighted with the results and would not go back. The lowest gear was a problem but from your previous videos chanced a 1.0 to 1.6 sprocket to chain-ring ration, based in my weight, giving a bottom gear of approx 21" and after 6 months there have been no problems. Found your information videos very helpfull.
I was overwhelmed but in a concise manner, I now can scrutinize my new purchases with your channel’s informing videos, outstanding you now have a new subscriber..
About the stiff shifter:
There is two shifting available: single turn, and double turn. The first one is stiff but you can go thru the whole range in one turn. On the other hand, the dual turn is much softer but you have to turn it more.
I have a 380 (for 3 years) & I didn't know that.
I think what is more important when comparing efficiencies of gear hubs vs derailleur shifting is the FEEL when pedalling under load. Obviously when simply commuting it is not going to bother anyone that much, but the longer your ride is the more frustrating it gets in my opinion. I couldn't care less about the extra 2 minutes on a 100km ride, but that feeling of each pedal stroke dissipating somewhere in the system finally got me. I know I'm exaggerating, but it felt like jogging on a beach vs jogging on asphalt, especially in lower 'gears' climbing uphill. I was nevertheless happy after I finished a Maratona d'les Dolomites (160km, 4000hm) on my modified BMC alpenchallenge with nuvinci 380 and gates belt drive 😅
Fine-tuning the gear ratio to find the best cadence for every specific moment is something magical and it is such a huge difference even compared to derailleur gear jumps. And I'm not even talking about rohloff with its 14% chasms between each gear. For everyone to understand - I'm mostly bikepacking on a road bike, so for me the optimal cadence/speed is important. And I do not mean always staying in 90rpm zone - depending on terrain/fatigue you would prefer doing 60rpm or 110rpm instead of the 'optimal' 90.
I also had a bike with pinion 1.18 for some time. Much better feel in terms of efficiency... And oh that amazingly light rear end 😊. But i was literally appalled by not being able to shift under load at all. I know all gear hubs have this problem, and even derailleur shifters can give up in certain situations, but pinion was the worst I've ever experienced when trying to shift to a lighter gear on a 15% climb.
So after a couple of years of experimenting I'm back to derailleurs and chains 😐
Thanks for taking time to write that. Ill be sticking with my derailleurs.
Thanks for all the advice, and for confirming what I’d suspected- that the local bike shop everyone else raves about has been trying to sell me very expensive stuff which won’t fulfill my needs! Mind you the dead giveaway was that whenever I asked some sensible questions and pointed out why something would be an issue for me they snapped at me, and made outrageous claims like “whenever there’s a fault it’s because the customer did something stupid” (for landing in a river,) and “our wheels don’t break” (neither did mine until I was hit by a car- that’ll break anything.)
you are forgetting the part where only a new and properly lubricated chain setup running the chain straight is more efficient than a belt.
once you ride in a gear where the chain can not be straight anymore you are losing power, chain slightly stretched ? loosing power again, chain not completely clean and well lubricated ? loosing power again.
the belt on the other hand doesnt have these problems.
@@Pixelplanet5 well then I guess I'm always riding properly lubricated new chains in the right gear :D ok jokes aside, I am not talking about efficiency numbers in relation to an absolute efficiency. I'm talking about the feel. Grinding up a hill out of the saddle with nuvinci felt like treading on something soft when compared to doing it on a granny gear with an imperfect chain line. You'll know what I mean if you ride around on nuvinci like I did for some time. Again not saying that the hub has no place in the cycling world - it does. Just not for me for the reasons stated above
@@Pixelplanet5 oh now I see that you only talk about belt vs chain. Ok then I can't disagree. My problem is not the belt though but the gear hub. I did not say that a belt drive is less efficient than a chain
As a road cyclist who occasionally uses these hubs when using bike shares, my biggest annoyance is the massive range in the highest ratios (which i basically always am in with these because they are geared so low for the average cyclist) this is definitely due to wear somewhere in the system, because when they add new bikes to the fleet they always have good ratios at first. Perhaps it is due to the cables or misuse/lack of maintenance, but with a bike fleet that is something you need to design for.
Came here to say this.
Where i live (switzerland) there are a lot of hills, so theres a lot of shifting under heavy load going on.
I very rarely see an enviolo over 10000km which still provides the full range.
As far as i know the problem is the disc which angles the balls in the hub, it wears out and is no longer able to maintain the balls at the maximum angle
I think this is cable related and probably not too hard to fix, using the electronic shifting might resolve this.
20,000 km is already not very long for a bike transmission to last, especially not for the price. And it sounds like it doesn't even really last half that. It's a shame, because it otherwise seems like a good idea.
Get over it...Buy a Rholoff and move on !!!or if you want extend your fleet...go for the Pinion....and you will sell your fleet and keep that one.
Yeah I think at max gear and higher power on a public bike you're also more likely to run into problems. My local ones skip to hell and back if you try and push high torque through them with lower cadence (I'm an extremely casual cyclist, might be missing something)
Recently got a nexus 8 bike after a long stint of single speed. I love the low maintenance of IGH and it's great to see another video on a lesser known one. Keep up the great content, we love it.
I thrashed two Nexus 8 sport over a year of usage and maybe 6k kilometers. After switching to an Alfine 8, the known weather seal weakness of the Nexus has finally stopped harassing me
@@PhilosoFox When was that please? I think Nexus and Alfine had issues, that were resolved around 2017 or so. Asking because I have a new bike with Nexus 8, am planning a lot of sporty riding with it
@@userdjee834 @philosofox I would also love to know if the nexus 8 has had revisions since your trashings.
@@userdjee834 Yeah, that was before 2017, since I'm driving my Alfine 8 longer than that now.
@@PhilosoFoxWell thanks for completing the informational big picture.
No one does equipment deep-dives like you, they themselves send you on a ride for 20+ minutes not including the rewatch value :P Also you encouraged me to go on my first bikepacking tour, so huge thanks for your contribution to the community :)
That being said, I traveled through Germany and France (parts on the European Divide Trail) on my Cube Travel Pro with a Shimano Nexus 8 Gear hub. While I had the time of my life and am hooked, I will never again bikepack on a hub with 308% gear range and 28" gear inches. Any hill with more than 3% gradiant was a major pain and required brutal pedaling (best I managed to climb was 9%). But most importantly the high gear jumps broke me. Not being able to find the right cadence turned out to be way more of an issue than I could have imagined. So even on flats I was constantly deciding between putting more effort into my strokes or fall back in speed considerably (losing momentum as well which only worsened my pace more).
The Enviolo seems really promising, if only they offered ~530% gear range, I'd be sold. Now I'm banking on either getting a used Rohloff (insane value on 2nd hand market in Germany, usually 400€-800€) or getting a MTB with a 2x11 drivetrain (maybe you can guess where I got the idea from)
I have been bike packing with a derailleur system, got an Alfine 8 and own a Rohloff now. By far the best shifting system I've ever had! It's so smooth, and with the range I can easily pedal 12% gradients. I was lucky finding a second hand Rohloff first, then built a bike around it :). Highly recommended!
We have 3 bikes with enviolo at my house. One of them is automatic and that is just the best. Wife preferred enviolo to rholloff so we got a tern gsd with it. She just didn't like pushing the shifter all the time as well as the noise. So far several thousand miles in on the 3 bikes and still living the enviolo. It's just so easy to use since I never have to remember to maintain it and get in the proper gear. Though I really did like the rholloff hub.
The noise bothers her? Get used to it, understand that it is not equal to drag, and after some thousands of kilometres of use, and 2-3 oil changes, the noise diminishes greatly. My Rohloff has done almost 70,000km and I barely notice any noise when riding.
@@petesig93It seems like she's happy with the enviolo, so why would she want to "get used to it"? I'm sure it's a minor complaint, but it makes the ride a little less pleasant and not everyone needs a high performance drivetrain. Especially when there are no oil changed to be performed for the life of the hub.
I worked in a company designing and building bikes for food delivery businesses and we used Enviolo hubs in them. They work pretty well under those conditions and if the survive non stop rough treatment by under payed delivery drivers well enough they should do well for commuting and so on as well. We also paired them with 70 Nm mid motors and even that did not harm them long term (for granted, I left after about six months, but in those six months they done about 200 km daily every day between three shifts, so I would say that is a long enough span to judge on given the sample size of about 80 bikes)
Super helpful video Alee! This has really helped me to assess the merits of thes different hubs! Currently really enjoying a Nexus 8 with gates but I have always been intrigued by the CVT hubs. It might have been cool to mention that Leonardo Da Vinci invented the first one in wooden mock up form! Your information on the gear ranges was particularly helpful!! I did not realize how limited the Enviolo hub could be compared to a Rohloff! Super information with amazing clarity. Thank you.
I love your videos. I'm a road cyclist, and I've never done any bikepacking or bike trekking
However I'm also a big technical guy so your videos are so satisfying to me
I personally have the pinion , rohloff , kindernay and Alfine 8. Love how robust the pinion and rohloff are. But my Alfine lasted me 6 months. Water seem to sip through and caused a lot of rust within the hub and the bearing race were so badly rusted the entire hub ceased. While the kindernay often have shifting issues and requires bleeding so very often.
Sturmey Archer and Shimano planetary hubs have very poor sealing against water invasion. If you look at a 3 speed Shimano or Sturmey hub you can actually see one of the 3 bearing sets, they are not even covered, much less sealed.
Which leads to the second issue, they are packed with grease at the factory, so you can't lubricate them, without disassembling the hub, and repacking, which is beyond the abilities of even experienced home mechanics.
@@PRH123 i have disassembled my alfine 8 and its do-able . but requires the TL7001 shimano tool to align everything back in place when assembling back . but still , using sealed bearings would be so much better. on a side note the alfine 11 / di2 are using oil bath instead of grease. they work alot better and also lesser resistance than the alfine 8 .
@@IvanLiew1404 yes oil bath is much better…. the very old SA 3 speed hubs were oil lubricated, with a fitting on the hub for adding oil…. They need to bring that back….
or transition to cartridge bearings, as they have on their other hubs…
Living off a bicycle for years now, I can not say enough good things about Rohloff: no more cassette to clean or buy, less chains to buy, no more derailleur frozen in position, can shift whenever as much as I need. Love this product. Got a Schlumpf drive on the front, love it too.
There is just 2 bad things with Rohloff.
Some sample variations. They do have some monday morning hubs with issues.(Rare)
The actual list price.
If you own a good one though. Your set for a lot of miles of near hassle free riding.
They do have the best product.
@@1barnet1 I was grinding through more than 120 dollars (low side) per month (rear cassette, chains, front cassette). Not to mention days, where I couldn't shift. Imagine that. You are riding about 80 miles today and your gear shall be frozen in place 3 days ago.
At this point tye Rohloff hub has been a great financial choice. The question is simple. How many miles are you going to ride. I live off my bicycle. Love their product. Change th oil twice a year. Replaced a paper gasket once. The oil is biodegradable. What's not to love about the price? Keep riding.
Hope your having a great week. Know your/you're love
Which Schlumpf have you got?
What were you doing to your bikes? I haven't changed a single part on my Mtb, and it's a 2012. Sure I've replaced chains when they are due, but never cassettes and such.
@@buckroger6456 living off of it, more days than not were 75-100 miles. So I was riding the hell out of it. Tried to take 1 day off every 14.
It is always a lovely day when Alee uploads a video. :)
Great comparison. I own derailleur, enviolo and Rohhloff bikes. The derailleur bike is a folder and the only one I would like to drive should the battery die. The enviolo bike is the best to use in the city, mostly because the shifting is much less of a trouble at traffic lights or when conditions change quickly. For long distance biking I absolutely love my Rohhloff although I do not particularly like its electronic shifter.
I've been riding a Turi from Priority Bicycles that I bought 3 years ago and it has a 300% ratio Enviolo rear hub and uses a Gates Belt drive as well.
I put 7000 miles on it before I replaced the front Cog because it was creaking: The belt had worn small cups on the torque side of its teeth. So I bought a new cog and while waiting for it to arrive I dusted the belt with CORN STARCH and the creaking went away! When the new cog arrived I replaced it and saw the old belt looked no different than the brand-new belt that I had been using as a spare and was in my road kit for 3 years. I put on the new cog and used the brand-new spare and kept the old belt for use as a spare, since 7000 miles hadn't harmed it. Seriously, it looked like it was new. My guess is these belts will last for 50,000 miles just like their big brothers that are inside many 4 cylinder car engines driving the camshaft.
Enviolo makes one with a higher ratio but the 300% unit works fine for the city. Priority sold me a smaller rear cog that worked with the original belt because I wanted a "longer leg".
I'm a huge fan of the Enviolo. I got a 600 recently for gravel and off-road use since the Turi is designed for sidewalks and paved roads. The 600 has a Pinon 12 speed crankset gearbox and is a great all around bike, but I still ride my Turi from time-to-time.
I have nothing to say about efficiency as I'm sure it's not as efficient as a derailleur. But as far as joyriding and commuting, I wouldn't have a derailleur or anything with a chain anymore. I feel like an emancipated slave: I'm NEVER going back to those chains.
As always, exceptional explanation on the hub engineering!
As someone who has been eyeballing a Dost bike with the Enviolo for the last year I really appreciate this video. Thank you!
Laced in one on my 33 year old MTB. Love it. Would never go back to a derailleur. Have the manual shifter and have had no problems with it. I was glad to see that you saw/know that they can not shift between high and low without the wheel turning. Not a real problem; even when I come to a stop; as I've already downshifted. Love how if I want just a "bit" more/less peddle, I can give the knob a slight twist and I'm good. I started out with a 34/17 combo on the gears, but had no real low end, so I went to 24/17 and can pull hills with the best of them. I don't have a very high end, but I never go over 15 mph anyway. The 34 is still on the front so I can pull the derailleur arm forward and change rings if I'm on flat ground and want to go fast. I wanted to have just a plain chain, but I couldn't get the right spacing with the vertical dropouts. So I modified the old broken derailleur arm and I'm good to go.
Always a joy to see a new video arrive. Great review. Thanks.
I use the enviolo in a bike share more than daily. Everything you say is very true, when wet it's almost impossible to turn the manual gearchange (although if you grip differently can help), and even being constantly abused, it feels more like a cable issue than a gearbox issue. But they still get very beat up
But being able to change gears while stationary is huge on cities with lots of red lights, worth the efficiency loss for me
In my personal view the only way to use a enviolo is with the automatiq only then the real advantages of the system become clear. The loss means its mostly useful for ebikes and yes the 10% extra loss (maybe as explained) is true but that just means you are one gen behind in battery tech. The jump from 500wh to 625wh or now 625wh to 750wh and 4 or 6 amps charging will take care of that. I ride about 60km a day on a reise and muller with enviolo automatiq changed my whole view on how comfy and fun riding can be that combined with our good and getting better bicycle paths in the netherlands.
Maybe spraying the rear mechanism with Corrosion-X would solve the problem
@@scb2scb2 Yo, still loving the automatique? Which R & M bike do u have?
@@ghagen888 Yes i now have 16000+ km on it. I have a nevo3 gt automatic with some changed parts. The only thing i didn't like where the breaks i upgraded them to the mdp models when it was time for some updates. Now the enviolo had to be replaced at 14000km not because it broke but during maintenance the shop made a mistake and broke it so they replaced the whole back wheel with a new one+enviolo+controller part. So i can't 100% say how long it would have lasted but it was fine as far as i can tell before they broke it :)
@@scb2scb2 nice. I got a cheap e bike as first my first. Next one i know i gotta put some money into it. I want that auto
I use a alfine on my koga bike but a enviolo automatiq on my riese and muller doing about 10k on it over a year. I know you touched a little on this but for me the concept of bringing the whole drive train under software control is key. The cvt can always be kept in correct mode (less stress on parts) and combined with a (ebike) good motor and controller you can always 'shift' and change how the bicycle reacts. This makes for a whole different riding experience i don't shift at all anymore and the new bosch system also has a auto mode that adapts to you so even that doesn't need a change anymore. The end result is i just peddle and go always at my speed (turns out 68rpm) we are already seeing special modes where like in a car you can set it in different modes to create different riding curves and more sensors are coming in to control things like abs, wet riding, tilt sensors to it detects hills up and down. The fact that the whole motor and gear system is stepless and my 'peddling' can be stable but the drive train can be flexible is perfect. Its perfect for the dutch roads i use it on. The only downside if i move back to a normal bike (in this case my koga) i forget to shift all the time. I think anyone should ride a enviolo automatiq for say 100km just to see how it feels best on a comfy bike like a riese and muller its just so relaxing and fun.
Great video, you do a fantastic job of hitting all the good points and also the bad points of the enviolo hub. Some videos I’d seen prior to buying a bike with an enviolo hub gave me the impression that there are no disadvantages to this hub but that just isn’t the complete picture.
One thing about difficult shifting and cable wear, I suspect the setup is poorly done, my bike had issues with difficult shifting and it took ages for me to diagnose it. If the cable lengths aren’t correct and the cable tensions are also wrong it’s very easy for the cable to run off its guide within the shifter. This can damage the cable as shown in your video or even damage the shifter itself (this happened to me…).
There’s also a significant lack of literature on forums, UA-cam etc. The enviolo support videos are less than 5mins in length and do not show you where you can go wrong (again maintenance is not a perfect world except on cleanly edited UA-cam videos…).
These hubs do have a place in biking but it’s not perfect by any means.
which hub do you recommend if you ride a bike a lot and need less maintenance? I currently have an Envilio 380 and I am thinking whether to change it to an Envilio automatic or a Rohloff automatic
@@mr.denoli7749 not having an electronic shifting enviolo or Rohloff it’s hard to say. Alfine di2 has complaints online as well. If you understand the setup for enviolo it should last (mine after heaps of stuffing about finally works fine and I understand what’s important when the tutorials tell you cable tension is important but without the explanation why and how much tension is required).
I’ll keep using enviolo 360ct but I think if I could spend big rohloff would be in my sights. If I get off my ass I’ll make a video about all the issues I’ve had with enviolo 360
I bought a low-maintenance bike from a company called Priority, in New York. I love my Enviolo hub. The bike also has a belt drive, and the frame is made of aluminum to avoid rust.
Priority is how I first heard about these hubs. How do you like yours? I was looking at the Continuum Onyx as a possible do-it-all bike
Great videos. I really enjoy cycling with hubs for transport. I'd love to try something with a belt too!
I am leaning towards the pinion gearbox for my next bike. They have the motor hub assembly for ebikes that is also attractive.
But there is a fairly large weight penalty over the Rohloff.
@petesig93 yes, but that weight is down low and in the center of the bike. That translates to a better handling bike.
@@buckroger6456 What someone needs to do is "fixed" gear cvt. Like in my polaris 1000c ATV. The speed spins the belt to higher gear. You can only do this with fixed gear as freewheel would drop you to smallest gear while coasting
Thanks for these explainer videos, i feel much better equipped to discuss bike models and features when looking at a new purchase.
You missed one thing about the weight difference.
For normal cargo/components you are correct. But for rotational unsprung mass, these weight differences become much more impactful.
If you're interested, there are a number of online calculators for that, and even if mostly aimed for cars, these can easily be used for bikes as well.
I decided not to place emphasis on unsprung mass as I don't think that full suspension bikes (and rough terrain) are the primary application of Enviolo hubs.
Fair enough, but doesn’t the fact that it’s rotating mass matter in any case?
@@AndreSomersNot much because the mass is near the centre of rotation. It's the moment of inertia of the wheel that matters, not its mass, when it comes to the effect it has on the ride. Moment of inertia is proportional to mass but also to radius squared, so heavy rims or tyres make a massively bigger difference than heavy hubs.
Our customers like the Enviolo.
But that depends heavily on the area of application.
Here in Germany, the enviolo is finding more and more followers.
I use the Rohloff.
It's the ideal solution for those who don't know where to go.
And I have to say I like the gears.
I have the feeling that I never hit the right gear with the Enviolo.
And as a touring cyclist, the Rohloff is of course better.
But both have their pros and cons.
As always a very good video.
I like to show it to our customers if they can't decide. 😅
The negatives outweigh the positives for me on this one... The lack of climbing gear, fiddly wheel removal, unreliable shift cable.... This thing is not for long-distance tourers.
Exactly. Restricted pretty much to those who don’t ride much. Cool concept though. Maybe a ring to ball to ring to ball to ring design would add enough range? But that would reduce efficiency even further. And add weight and probably limit the torque even more. Oh well.
which hub do you recommend if you ride a bike a lot and need less maintenance? I currently have an Envilio 380 and I am thinking whether to change it to an Envilio automatic or a Rohloff automatic
@@EricPeelMusic For my e-bike with about 50 miles of real range it seems like a fine system. Even with the Rohloff I'm still limited to battery life.
Amazing video. The engineering on these hubs is top notch. My next ebike will have one:)
The comparision is fair and done with a really comprehensive overview!
In my =opinion= the Enviolo is only an option, when we are talking about E-Bikes. In this Application the lack of efficiency is less important, because you get the "dissipating power" from your electric motor. But it still "feels" a little "soft" while pedaling.
But yes, the advantages are justifying the power that is lost in the hub: It is a good hub for everyday use, especially in combination with a belt drive and an automatic shifting, because you do not need to think about ist. It just works.
On the other hand I have one Enviolo in my household that failed within less than a year (a "Heavy Duty" in a R&M Multicharger). The guarantee-handling was/is poor and so are the repair-options because there are simply none: You can just exchange the complete hub, that's it. The wear of the (inner) cables is also legendary, the 90° change of direction within the shifter is just poorly made. Another crazy thing is the "reset-problem" of the hub interface mentioned at 14:40. Why is it designed that way?
But again: Even though I personally would prefer a Shimano over an Enviolo*, I recommend an Enviolo hub for Riders of E(!)-Bikes that don't want to think about shifting, maintenance and all the other things.
*but I am riding only Rohloff 🙂
Great video and comparison. I chose the Enviolo for my first trike. Having a derailleur bent for an unknown reason on my main ride I decided to make the change on my future rigs. Rohloff was a choice but given the price and having electric assist, it would have been superfluous.
I'm amazed by the double standard.
CVT is perfect because optimal pedalling efficiency is always achievable as long as you don't care about the overall efficiency.
Derailleur is bad because you can never have optimal pedalling efficiency.
Breaking news: if you don't care about everything else (your main argument for accepting the huge power loss of the CVT) you can also have constant perfect pedalling efficiency with a derailleur. If you feel like you are between 2 gears you can simply chill a bit and select the easier one. This sacrifices a tiny bit of speed (most often less than the 14% power you constantly sacrifice with a CVT). Instead of wasting those 14% energy from your last meal, you can use it to go further with a calm pace and without a sweat.
Amazing video: super-interesting, to-the-point, well-structured, complete! Thank you, I have learnt a lot!
Thanks for posting this, it was really interesting and will be very useful knowledge for looking after mine.
Very interested for use on my high wheel….probably have to build a new wheel for it..36” may be fit a front wheel , all depends on the axil I guess..dun-no?
Thanks for this detailed video. I'm very interested in CVTs. I first noticed them on your touring bike with the belt drive. I'm going to look into getting this kind of setup here in Japan.
5:10 that hit hard. my friend who has a lame right hand aked me to help build a geared bike that can be controlled by the left hand. i was stumped. lets not forget about left handers. honestly we need to ask for left and right hand gearing regardless of the system.
but the button press gearing for be really god for someone like my friend. good point
From memory, Rohloff makes both left and right handgrip gear shifters.
The speed change happens because of the distance of the contact patch from the centerline of the axle in the ball. When the output contact is closer to the axle, the diameter of the contact path is smaller, so it's like having a smaller sprocket. When it is further from the ball axle, the diameter of the contact path is larger, like having a larger sprocket
I have one of these on my Tern GSD10. It's a pedelec, which means I can't really comment on efficiency. But it also isn't an issue. I really enjoy that I have full control over the gear I choose, and to be able to adjust at any time. I probably wouldn't choose this for a non-pedelec bike. For an ebike, it's perfect. Also, the Tern is ridiculously expensive (my wife pulled the trigger on that one), but I find normal bikes suboptimal by far now. It has excellent balance, excellent suspension, adequate pedelec support, and I can transport two relatively large kids and their school bags without even thinking about it.
Fantastic video brother, incredible 👏 👏 you are a hero!
Very interesting video. I have a Van Nicholas touring with an 18 speed Pinion gear box, and a Schindelhauer Heinrich with Bosch motor and Enviolo Automatiq. Where I live in western Massachusetts, it is pretty hilly and for day rides I get out on a good amount of gravel. The Van Nicholas is great for touring, but I find for daily use (errands around town or out for an afternoon ride) I turn increasingly to the Schindelhauer/Enviolo. In "Touring" mode I go up the 7%-8% grades around here, and it is so quiet and trouble-free. I thought I would miss the wider gear ratio of the Pinion but even with a bit of off-road the e-bike more than handles it. Service seems to be widely available and a local shop will handle the Bosch+Enviolo hub, a combo which has a reasonably wide distribution in the US. Love your Buyer's Guides, BTW.
In March 2011, I had a NuVinci N360 (Pre Enviolo) installed on my Rivendell Atlantis. It worked OK but shifting required some effort to twist. On mine, it would drift out of position (gear) at highest setting. If it would stay in gear I would have kept it longer. I sold it in 2016 as I was not riding it much. The pros and cons depicted on this video are consistent with my opinion. I would have loved electronic shifting.
I have experience with the rolhoff, enviolo and nexus 5spd e hub. All on urban arrow cargo bikes. I actually prefer the nexus over the enviolo but the rolhoff is crazy good!
If I had to pick I'd be going nexus. They just work. The indexed twist shift isn't bad, feels similar to rolhoff for get up and go whereas the enviolo feels somewhat sluggish. Plus the cost of the nexus is hard to argue with!
Well, I can certainly appreciate the evolution of internal gear hubs. Now, my bike, an Apollo from 1962, is working on a three gear internal hub. It has done so since the day it left the factory. It hasn´t needed any oil change. It has always worked. It does not make any sound when I change gears or while driving. I can change gears while stopped (not recommended, as the third gear is quite strong to pull).
I have the feeling that this is just another overengineering case, an illness our society is strongly suffering from. Again, I appreciate the idea and advantages, but normal people will never exceed the need for a lower first gear of mine, nor will they find third gear not enough for speeding.
Combining bycicles with mobile phones on the other hand seems to me like getting crazy. We have now around 240 million cases of serious neck problems and that is only the tip of the iceberg. Mobile phones are the worst idea ever and people should start to STOP using them. As flexible I am with innovation, on that point I completely go the opposite and condemn them. I am now the only person in my city without a mobile phone, but some years from now, I will have been a pioneer instead of being laughed at.
And yes, I am as old as my bycicle. In fact, we were "born" nearly the same day. This may explain some of my stupid texting, I hope.
Kindest regards and the very best to you and your beloved.
Miguel
I have one , it works very well, dont notice any heavier paddling
I’d be interested in a comparison video between Rohloff and Pinion, as their ranges are more suited to my style of riding as I frequently ride up 17% inclines and my lowest gear on my Brompton is 28” from a 44T chainring and sometimes feel a lower gear would be preferable. Similarly, my MTB needs a wider range than Enviolo can offer.
On a 4.8 fatbike tire with some day bikepacking gear, I will ride up 18% grades fairly frequently. As a senior I find myself looking for even lower gearing and I do not like walking, lol! Who cares about the top gear, as I know how to still spin and tuck as I do not really care about lots of speed any more. :)
i watched one of your other videos and i left a comment.. i tested some enviola hubs and i liked them.. i also tested a shimano alfine and i didn't like how it shifted and how it clunked.. i would like to test a rohloff but i still think that i will like an enviola the most.. especially on an ebike..
Ease of maintainability is a big deal. The cost difference in servicing an Alfine 8 vs an Alfine 11 makes the Alfine 11 much cheaper in the long run even though the initial purchase cost is higher.
Except it sucks. I have it, it's by now a whole parade of gears are not usable, start skipping under load.
@@huhummmmmmm Did you perform the recommended yearly maintenance? Have you sent it to a bike shop to be looked at? It may need some tweaks to the barrel adjuster. Or it could be something else entirely.
Excellent video and presentation. Thank you.
I got it @ ebay for 180 american rubles 10 years ago with a warranty of 6000kms / 3 years and it's been 10 years ~20000kms and i feel like only the force required for rotating the actuator got increased, but still works fine. Maybe I'll have to change the wires but I want to upgrade to n380 with a belt. Absolutely recommend it. It's best thing that happened to my bike, as I wasn't feeling like to ride that long and were feeling tired due to shift ratio changes.
Added note, automatic shift is not for hilltowns as the optimum rpm changes as the elevation climb rate changes.
Better if they did it lighter instead of stronger. I mean, the design is strongest anyway, just a bit heavier than 1400$ rohloff.
After riding the auto shifting Enviolo (with Specialized interface) i did not want to go back to manual shifting of any kind. You can still adjust cadence on the fly.
I agree, the auto shifting is really nice to use!
My wife and own 4bikes with enviolo and we love the ease of shifting to keep the pressure off of your 70 year old knees
3 priority bikes and 1 Himiway electric bike
The beauty of bikes is you can have a 40 year old frame, just switch out a few worn parts and off you go. I actually like shifting. My car is manual shift also 😊
Thank you for explaining the Enviolo hub. Looks like a viable alternative for some riders. For your next tutorial on bicycle geared hubs, please consider doing one on the Kindernay.....Pros, cons and who might benefit from it's use. A similar formatting as this video would work well. One of the cons (in my mind) to the Kindernay is the hydraulic shifting. If they offered mechanical shifting as an option, I might give it more consideration. What is your take? Thanks for another in depth explanation of bicycle systems..........Be well.
Can't wait to get one of these on my gravel bike! I don't care about a little more "free resistance" or weight. I still want a loud freewheel so people hear me coming on bike paths though. ;)
Great insight, thanks. I was wondering how it worked. Can it work with a torque sensor?
I think a 'continuum range' would be a better descriptive than 'infinite'.
I've been wondering if a strain wave (or garmonious) gearing would work on a bike?
yes it does many brands (i use a Reise and Muller bike) use a combo of bosch midmotor (cx mostly) combined with the enviolo automatic. The enviolo can work by itself but some brands (bosch for example) have integrated it into their controllers so you can control the enviolo (see 'gear' and set peddle speed) on the kiox display and buttons near the grip. Not 100% sure what the integration does but to me the combined software (or under control of the bosch maybe) feels smoother than if the inviolo doesn't know anything and does it all by itself. Hope this makes sense the bosch system so the bike uses torque sensors, peddle speed and wheel rotation speed even if the enviolo doesn't directly use the torque sensor the whole bike does so create the best ride. I did 16000km on mine sofar.
@@scb2scb2 Man, I'm looking forward to be able to put some serious miles on the clock like that when I get an e-bike.
I'm supposed to be choosing one, but actually just nerding out on the variations.
I live in a very hilly city (Bristol), so that's probably gonna be the deciding factor in the end.
I love the feeling of riding Enviolo/ NuVinci Hubs but i'd prefer a broader gear range. I've never tried HarmoniQ or AutomatiQ but I'm stoked to do so. Thank you for the most detailed Tech Explanations on the best Bicycle Technologies
Use a 3 gear crankset....
I love that even after 120 years regular people aren't switching to internal gearing that doesn't get all mucky, and get get stuck in the wrong place.
I hate to put a downer in internally geared hubs, but I spoke to a few bike shops in the past 18 months, and they all love them. They are apparently very smooth and easy to use.
That said, they all commented that when they go wrong they are a complete pain to sort.
I can only assume that here in the UK they are quite rare, and assuming rarer faults, means that mechanics really aren't familiar enough to be efficient are repairing them.
Great insight 👍 If the primary application is off road mountain biking non EV.... go Rohloff ?
You got it. 👍🏻
YUP, only Rohloff!
Why do we have to pedal at the same cadence all the time? Would it not be healthier to vary the cadence, pedal fast sometimes, pedal slow sometimes, pedal hard sometimes, pedal easy sometimes? My single-speed or three-speed is perfect for this.
The belt drive is perfect. Why is it so difficult to find a bike with belt drive?
Might depend on country more and more bikes here (netherlands) use belt-drives my normal bike koga also uses a belt drive and internal geared hub.
I have been using a SRAM AXS electronic shift system for two years. Last year on the North Cspe 4000 I a managed to get about 1m of water between the. Ottoman of the tyres and my backside in a flooded underpass I though had 1cm of water in it. And this year I did the European Divide Trail Adriatic to Baltic Off Road route (3000km) mud was in my teeth, hair, all my bags and I had to clean the bike off every 200m on one section of 4km. My point being the electronic shift has been a joy. There has been zero mechanicals caused by it. I suspect electronic shift will come to all gear change systems for all riders on all bike gear systems ( E bike or not ) in the next couple of years. Maybe in under 10 yrs it will be the default option on the just above lowest price and middling to high end bikes.
Love my Enviolo hub! Would definitely recommend for a daily ride/commuter! Toying with building a gravel bike with a Shimano hub and Di2 shifting one day though!
This is EXACTLY the type of video I was looking for. I've been contemplating the Priority Continuum Onyx with a CVT for a while now, but couldn't find any good direct comparisons between other hub shifters. It seems clear that CVTs are the way to go for low maintenance city riding.
I saw at least a couple people mention that enviolo hubs have a break in period where the transmission feels sluggish brand new. Did you experience this yourself?
Yes they get smoother after about 500km but personally for ebikes i would always go with the automatiq it just changes the whole riding experience ...
I have been riding a Priority Continuum Onyx with 380% Enviolo hub almost daily for over two years of city commuting in all sort of weather including rain and snow. The hub has been flawless. I did have to replace one shift cable recently. The cable problem was caused by one of the wires in one cable breaking at the rear wheel part. That broken wire then unwrapped itself from the rest of the cable, eventually propagating all the way up the cable to the shifter and then bunching up inside the shifter.
I think the design of the little part the cable attaches to at the rear wheel is the problem. You're driving a screw down directly onto the cable to clamp it. Apply a little too much twist on the screwdriver and the screw can chew through the wires. It should have a clamp that is pushed down on the cable instead of directly smashing the cable with the screw.
Nice piece. Thank you. I find my NuVinci 380 a bit syrupy, especially when pedalling hard. If you're climbing a steep hill a fairly high cadence (75+) and low input torque seems better than vice versa. After all, you are squeezing a non-Newtonian fluid between two surfaces under very high contact pressure (at least that's how I assume it works). On the other hand, it does seem that on the flat, at least, the faster you pedal the more 'lossy' it is - which stands to reason I suppose.
When the time comes I intend to do a bottom bracket ebike conversion. I think it will really come into its own then, even if it's not an auto.
I have been riding a four speed hub gear bike from time to time since 1970, the hub has a notably dreadful reputation but the steps are very nice plus for town use you never distracted with gear change because you can change gear when you like. I think I'd miss the steps, but on the otherhand, I also had an automatic CVT on my moped that was nice it went up ratios speeds with light loads and higher speeds and used a governor with ball bearing as the rotating weights.
I would like to try one and that feature of being able to maintain a set cadence in the automatic version is outstanding too.
It's a very cool feature. I've been able to test a few more automatic CVT drivetrains recently, and will hopefully shine some light on them too!
As someone that tried the old auto-shift derailleurs bikes. It’s really not ideal especially if want to put any kind of power or going up a short steep climb. Maybe with electric assist and use of modern bike computers you can make it better or offer more control.
@@Cyclingabout I'm yet to find any other automatic shifting that is as good as mine. I use power data to adjust my cadence automatically rather than maintain a fixed cadence like other automatic shift systems.
I soured on enviolo after it failed on our Urban Arrow after only 3800 miles. They replaced it under warranty but it took quite a while to turn around.
i just got a qwic atlas vario, with the heavy enviolo and belt drive... biked 80k with the motor off, almost all the way, it was a pleasure even if its only 83 percent...
I tried it once - and I _hated_ it.
I wanted to like it, really liking that the bike had a belt drive, liking the idea of a maintenance free drivetrain.
And at the start of the ride, I liked it. Especially the possibility to change the gear ratio while standing was great! And for the first few minutes with several stops at the traffic lights, I enjoyed the ride.
But then... It was an electric bike, and as soon as I was above the support threshold it was like pedaling through syrup. Especially going downhill was terrible, I never had to pedal _against_ a resistance downhill to keep my speed.
I immediately returned it and chose another (conventional) drive.
Outstanding video - great explanation and comparison
Glad you liked it!
My first experience of one of these was on an ebike, under the Nuvinci branding. With the 250w mid drive it was incredibly sluggish. My following experiences have also been with ebikes and again were incredibly sluggish. Nuvinci, or Enviolo refuse to publish the efficiency of their hubs, and they make a very large effort to convince people that third party testing shouldn't be trusted. They know these hubs aren't efficient but won't admit that, and they'll only get worse with age, not better. The twin cables also make puncture repairs very annoying. I absolutely hate these hubs, I hate the company, they're unbelievably heavy, and aftermarket support is very lacking in many parts of the world. I contacted them once about some bearing play from the shop I worked at, and the response was less than helpful, implying that replacing the hub at full price was the most convenient thing for them.
which hub do you recommend if you ride a bike a lot and need less maintenance? I currently have an Envilio 380 and I am thinking whether to change it to an Envilio automatic or a Rohloff automatic
I'm 71 EVELO Omega (electronic Enviolo). I LOVE IT !
I am looking for fat tire 4.8" bike same setup for winter riding ??
Suggestions ??
Great video but do you have a mechanical clock near your mic?
Please do a video for retrofit 'bottom bracket gears':

2) Kappstein Doppio gearbox
3) MagneticDays Binary Gears
Few points on Rohloff. Many owners say that gears 1-6 are basically never used. There are reports of oil leaks. Lastly, there are complaints about the noise in certain gears.
Depends on what you are using your bike for. On a city bike the 520% range is likely overkill. On an MTB it is not (I certainly use the lowest gears a lot).
I never had any trouble with oil leaks but I can only speak for myself.
And yeah, every gear has its own sound. Not a big deal IMHO.
The reports of oil leaks are largely exaggerated. It's pretty much the same few repeated again and again year after year, out of the many thousands of Rohloff hubs in use. I wouldn't worry about it (and I don't - my Rohloff doesn't leak). I use gears lower than 6th all the time, and I ride in a city. It's just a hilly city. Also, using lower gears up hills gets me longer battery range on my e-bike - rather than using max assist in a mid-gear, I can bump the assist down and use one of the lower gears. 3rd comes in to play regularly, and I've used 2nd on one particularly nasty hill. 1st is just fun every once in a while lol. But I use 4th often. And as for the noise, it ticks when coasting just like any derailleur-equipped bike. The nature of the ticking is different between the 1st-7th range and the 8th-14th range because of the reduction gear. But it is true that it is not silent like a Shimano 5-speed e-bike hub (I think it's called the Inter-5?) that I also have experience with, or an Enviolo, but I don't know why anyone would complain about normal bicycle gear sounds. The wind drowns it all out above 10 or 12 mph anyway.
I'd recommend trying every gearing option before buying an expensive bike tho. Sounds that don't bother me may drive somebody else nuts, who knows, and be sure to go up a hill to be sure the lowest is low enough. I tried an Enviolo-equipped version of my bike before buying, and I really liked it. Very smooth, totally silent, decent range. I'd totally get one if I lived somewhere flatter. But the hills around here, many above 8%, some up to 15%, plus the relatively placid cadence of around 78rpm at max assist speed of 28mph/45kph in 14th, made me bite the bullet and shell out the wince-inducing extra chunk of money for the Rohloff. It hurt, I ain't gonna lie. But this was a long-term purchase and I'm glad I did. It's been brilliant.
If gears 1-6 are "never used," then the bike is obviously undergeared! Rohloff is the benchmark for IGH, and not by accident. Speedhub 500/14 has the most user friendly gear range, efficient power transfer, enviable reliability and after sales back up. I considered a Nu Vinci some years ago when they were available cheaply on eBay, but lack of gear range and sub 90% efficiency were deal breakers. I spent much more on a Rohloff and have never regretted it. Annual oil changes and one set of replacement cables is all it's needed over several years. Tough to beat on all counts.
In addition to my Enviolo NuVinci 380, I added an ENFEO GTRO (Internally Geared Front Chain Ring). So now I have 3 chain rings, no derailleurs.
I feel that the lack of low-end gears are the biggest issue for me with the Enviolo. There are plenty of urban areas with steep climbs (DC, San Fransisco, etc.) that just wouldn't be great to ride in with this hub, at least without electric assist. With a Rholoff, you can just downshift to the lowest gear and can climb it without even sweating.
Can’t you modify this by changing the bikes gear ratios? Of course, this would take some off of the top end. The 14% efficiency loss is my biggest concern. How could you stay with the group in a group ride unless your 14% stronger and in better shape than everyone else?
@danparish1344 It's not for group rides. It's for city travel. The ability to rapidly shift gears is great for cities since it's stop and go. As for switching gear ratios, it's the torque limits that make it an issue.
@@TheSJCieply I used the bikeshare in SF for many years and never had too much of a problem climbing. They get plenty low. I'm relatively fit though. But the CVT plus an ebike means anything in SF is climbable.
@@AJHillis Most of bikeshare bikes are climbable, but you'll get really sweaty going up the hills. If you have a well designed hub, you can just downshift to a low gear and ride up the hill at a gentle pace. There's a big difference between being able to climb a hill and being able to climb a hill comfortably while carrying a load of groceries, tired after a long day of work. For that you need a quality bottom end gearing.
i ride my non-electric bike with an enviolo on my 11+ mile DC commute every day. there may be places in the world where the climbing gear isn't low enough, but DC isn't one of them. i extremely rarely even use the lowest ratio.
Alfine 8 is quite smooth riding hub. No drag that annoyed me. I had it with di2. It was great! I'd take di2 any day!
I really like the Alfine Di2 hubs too! We're getting a bit spoiled for choice these days. 😎
Agree, my Alfine 11 with DI2 makes derailleurs feel primitive and love the silence.
I have been looking at ebikes and I think I want something like an enviola hub, electronic shifting, and chain drive. I would just be using it to ride around in Germany. It seems to be a good option.
15.32 Yikes! That looks a really dangerous place! I have had an N360 Nuvinci hub for years and concur with everything said here. Never had trouble with cables though. Great video 🙂
Thanks! The location is "Death Road" in Bolivia.
Eight months ago I got a Specialized Vado 5.0 IGH with the Enviolo AutomatiQ gear hub to replace a 2020 Specialized Como 4.0 with a derailleur. Both are e bikes, and I live in the mountains with a normal morning ride of 20 miles and 2,400 feet of elevation gain. The loss of efficiency on steep terrain with the Enviolo is dramatic and extremely disappointing. I went from a 500:watt battery to a 710 watt battery, looking forward to an increased range, and yet because of the decreased efficiency it has roughly the same range as the smaller battery. In order to climb the steep hills in my area, I need to increase my assistance level 1-2 levels (with only 3 levels available). The old Como feels like a race bike compared to the sluggish Vado. The Vado with the Gates carbon belt is much noisier than the Como with a chain (have no clue why?). My wife and I joined another couple on their new Specialized Como derailleur bikes for a 240 mile ride on the Katy Trail, averaging 40 miles per day. I am a much stronger rider than the others, but stayed in the back per wife orders. We all used the lowest level of assistance for the entire trip, and at the end of each day I would compare the stated range left on my Vado to the other couple’s Comos. They also had the same size battery as I did. They typically had 20-30 more miles of expected battery life than I had. According to the Specialized website, expected battery range was predicted to be identical between the IGH vs derailleur equipped bikes! Liars!!! And to think I paid $500 more to get a less efficient bike with less range and noisier to boot! What a sucker I was . . .
The main loss in these types of CVT or Variator as they are called in industry, is in the ball bearings that apply the load to one or other of the input or output.
It would be wrong to think that the 'no contact' is unique to this drive, all rolling element Variators rely on this phenomenon as do ordinary ball and roller bearings, where in normal use the balls are not in contact with the races.
It would also be wrong to believe that 'no contact'= no wear. All rolling element bearings suffer from extremely high near point contact forces leading inevitably to fatigue of the ball and the surfaces they run on.
The well known Kopp Variator is very similar, just inside out with the idler being an external ring, this is not a new idea.
Very well explained. Liked & subscribed!
Many thanks!
Very good and realistic comparison ... but I am addicted to the Rohloff 😀
If you like shifting the rohloff 14e is the best if you want to just peddle the enviolo automatiq is just so comfy.
I would really like you to do a video on the best bikes (and ebikes), and gear hubs options for the steep hilly areas. I live in San Francisco and some of the hills in the city are 20-24% grade. I test rode the Enviolo and compared it to the 9-speed traditional derailleur did not really like the Enviolo. It has too much resistance and not very efficient. Perhaps the gear range is too short. The Rohloff is better but the bikes are too expensive.
maybe at that grade its better to walk anyways. The endgame here would be to pave the world so that we can cycle up vertically? Walking wont kill you.
@@RV-jq5pb E-Bike baby!
Interesting! My car has an automatic CVT gearbox, I initially found it weird because the engine drones at the same pitch irrespective of the speed of the car. I guess that's because it's the ideal, most efficient RPM for the engine. I didn't know CVTs were available on bikes but it should offer the same advantage of a consistent cadence at any speed.
You're car has a CVT? That's pretty remarkable! Is it an old DAF by any chance?
Almost all Subarus and Nissan compact to midsize cars have had CVTs for a decade now. Not remarkable whatsoever.
I guess it could be a regional thing then, here in Europe/just the Netherlands? After some digging it seems they’ve been pretty much phased out for a while now, although they never were rare quite to the level of just being in DAF cars.. thanks for the heads up, I now have some weird need to try a CVT equipped car some time.
@@FjodorvS I once owned a gen 5 Impreza and enjoyed the CVT very much. It was nice to cruise on a long flat highway and achieve 38mph, 2 over what the car was rated for. From 0-20mph it droned about 1200rpm then from 20-70 it gradually increases to 2000rpm. No shift lurches. You can really feel the efficiency over a regular automatic. And of course there's the ability to use the paddle shifters, drop down a few preprogrammed ratios, floor it at 6000rpm and feel like you're in a race car.
@@EricPeelMusic That sounds pretty fun indeed!
Thank you so much for making this. I wish to buy an e-bike and this is exactly what I wanted to know!
Love that "number nine" just like from Beatles' White Album
Fun fact: this cvt is technically a planetary gearbox with gear teeth being surface roughness of discs and rollers.
Not so fun correction for 21:55 - it changes the position of the contact patch, not size. But yeah, if you do the full rotation of the roller "sphere", you can say the ring area of all contacts is bigger or smaller.
Is there a list of bike manufactures or models that have these. I googled and found zilch
same here. i'm trying to buy a bike with it today and can't find anything
This flows like an infomercial and not a comparison to rohloff. Losing 17% in efficiency, especially with a load is nothing to sneeze at.
Done about 30'000km with the Nexus 8 IGH. Now, after another 30'000km on a traditional 3x9 setup, I am again considering Alfine 11.
Shimano 1x11 is simply the right combination, be it a hub or cassette. I don't ride much and continiously one type or another, always keeping all sorts of transmissions - always come back to XT 8000 or 700 Alfine.
@@feedbackzaloop I have a tandem, so I am stuck to the frame. Which means, in particular, that I have to stay with a gear that is "O.L.D. 135 mm" compatible.
This excludes all new MTB/Gravel/Road groups. The CUES remains the only choice other than an IGH.
@@PrzemyslawSliwinski Pretty much all gears fit 135 spacing. Actually, it is up to the hub design, not cassette interface. And most used road/gravel 142mm standard is simply 135 with different endcaps. You can swap them and continue enjoying the simplisity of open dropouts.
It is only the very new hangerless SRAM that requires a custom adapter.
@@feedbackzaloop Whoa! Does it mean I can use any Shimano MTB 12sp freehub - just need the TA to QR adapters?
@@PrzemyslawSliwinski Absolutely! Or a Micro Spline QR hub from the start
Hi! Any reason to not have made a comparison with the Pinion drivetrain? It's known to be heavier and have a slight deficit of efficiency over the Rohloff...
