Let me add a praise for this transmission. I bought an Nviolo a year ago. I put a TDZS 350watt motor on my bike, but I had 2 years of wear on the derailer which did not want to continue to operate on the 6 or 7 top gears. The chain would jump or even pop the chain link. With the Nviolo I do not have chain problems and I can always find a gear ratio for current performance needs. 6100 trouble free miles for the year.
I bought one of the ancient first generation NuVinci hubs, way back in around 2006ish. I spoked it myself, tensioning it by plucking the spokes till they all "sounded" and "felt" right. It was paired to a rusty old Huffy 314 with magenta mountain bike handles and an inverted set of speed handlebars... It was truly Frankenstein's bicycle... But I loved that bike. I rode it till I cracked the frame (broke the main crank bearing off the seat downtube, and started cracking the rear fork). I was gonna weld it, but then the bike got run over... I still have the mangled mess in a storage shed, NuVinci still intact, fortunately... My little hill guy cracked, but it still works. I'm a decade older now, and a little more creaky... Maybe I could fit that hub to something like a comfy recumbent someday...
One thing that I'd like to mention in regards to not just the Enviolo hub but other internally geared hubs is how the wheel is laced when compared to a conventional cassette setup. If you imagine looking at a bicycle from the rear, you'll notices that the spokes are offset on a bike featuring a conventional cassette and derailleur. Essentially, the relationship between the hub, spokes and rim forms an acute triangle. This results in a lot more stress being put on the spokes on the cassette side. This makes the wheel significantly weaker and more prone to buckling. On older, less well maintained bikes, spokes invariably break on the cassette side of the wheel. When viewed from the rear, you'll see that the relationship between the hub, spokes and rim on an internally geared bike form an isosceles triangle with the tensile stress evenly distributed across the left and right spokes. This makes the wheel much stronger. In my opinion, it's worth consideration if you are a heavier rider or if you plan on carrying a considerable amount of weight in your panniers.
I'm just relieved Nviolo is still around and better than ever after a shake-up at the company in the past couple years! What a vote of confidence being on bike share, needing no internal maintenance, and Chris vouching for their reliability over years with his customers! Integrating it into the motor is a great idea but I won't care unless that motor is QUIET like the Bafang one rather than the obnoxious Bosches. I wish there were a glut of Bafang, Nviolo, Gates belt, front suspension, fixed front rack, integrated lights bikes rather than it all being Bosch. I LOVE Bosch's system but that motor noise KILLS me. Your tech talk is the heart of your vids, Court, so no need to apologize! Fantastic overview comparing all the different specs' pros and cons, with likely applications and in-the-field insights from Chris based on his clientele's experiences.
I've been riding a Gekko FX trike with a Nuvinci for about 4 years now, and I absolutely love it! I'm 70, have fibromyalgia, asthma, and COPD - I'm a slowby all around. I chose the Nuvinci in order to choose my "speed" minutely, and it has absolutely met my expectations. I also have a super granny on the front (22 tooth) that I added to the regular 2 sprockets rather than down-gear all 3, and they work out very well. I went to Morro Bay this week, and while I had to pedal-rest-pedal-rest, I did make it up the nice, steep hill. (I live in the flat side of Bakersfield - not a lot of hills here.) I'm working on getting into better shape now that the air quality is better - had to stop riding with the Calif fires - covid has been a godsend to the asthma - I've been able to start riding again! Hooray! Anyway - thanks for a great product with the Nuvinci!
My wife has the Nuvinci 360 on her Workcycles Secret Service. After 5 years and 3,000 miles, the Nuvinci hub has never required any maintenance whatsoever. Even the shifter cables have never needed adjustment. Plus, like with any IGH, the chain, chainring and cog last way longer than a derailleur set up - since the chain can be wider (therefore the ring and cog are both thicker metal - and wear slower). The drawback to an IGH like the Nuvinci is the chain must have a mechanism to adjust chain tension, such as an elliptical bottom bracket or chain adjusters in the rear drop out. Both add some complexity to pulling the rear wheel to fix a flat. That said, I have found the Nuvinci hub itself is not hard to disconnect from the shifter cables to pull the rear wheel.
I just got into biking like a month ago, riding upwards of 15-20 miles a day. I'm saving up for a Priority Continuum Onyx (Enviolo hub, belt drive, but not electric-I'm not into it). I've been riding a borrowed WalMart bike-something new breaks every week. Can't wait for my own sturdier, nicer bike.
Okay now i get it, internal hub shifting is like driving a manual clutch stick shift where you ease off the gas to clutch shift. Internal hub shift just ease off the pedaling and shift at the top/bottom of the pedal stroke! 👍
@@MrPillowFoot thank you. Have Alfine8 on Kalkhoff Integrale, its so much better to ride now with timing my shift without false shifting. Almost like mx5
I like the detail that EBR goes into for the overview It must be nice for professional riders. But for beginners like me it's very hard to tell how this bike stacks up vs it's competition. I wish you would compare it with other bikes in it's price class and let me know how it stacks up. Unless I am very technical on bikes after watching an EBR I don't know whether or not this bike is a good value. This is very important we are talking about a very big purchase.
I'm 77 retired and love the quality of your bikes. Here in the beautiful Napa Valley they are developing trails for jogging or walking and now I see e bikes more every day. I will by a E bike but the selection you have are peddle only that won't work for me. Come on guys I want one of your great bikes but not untill a throttle model. Give us old guys with bad knees. Have a great day.
On this system, you can create an automatic transmission. It will be just an explosion in the bicycle industry. It is only necessary to install a sensor that measures the angles of inclination and speed, a controller that will control the servo drive that tensions the cables and changes speeds in auto mode.
You don't have to back off when shifting. The hub will shift fine during the dead spots in your pedal stroke. Acceleration is one of the things I love about having a CVT.
I built 2 ebikes with banfang fun 8 crankdrive motors and N360 hubs with harmony electric shifting. Mine is mated to the BBS2 750w motor and has always worked well My wife's bike is a BBS1 350w hers regularly loses the autoshifting function resulting in rapid peddling stuck in low gear, she has to stop and do a reset to get it working again, something I have not been able to solve. Having first ridden my bike with manual shifting which feels stiff under load I think the harmony system works better, if I use manual mode the twist shift is very light to use and would suit people with weak hand grip.I never need to lift off the peddling pressure the shifting is buttery smooth, when I had the BBS1 set up with derailuer gear system shifting could be quite harsh and jerky I felt the derailuer and chain wouldn't have lasted very long. It's fun to ride my 750w in manual mode using the throttle gently to avoid front wheel lifting and get moving to a fast walking pace then rolling on the shifter it actually feels like a throttle giving smooth rapid acceleration up to 28 mph, also running between half and full power on the thumb throttle you can speed up and slow down using the gear shift in manual mode it's good fun off road.
As every hubgear the Enviolo is safe from damage and low on maintenance. Right. But the argument that it allows being on the right gearing all the time is not that real. After a couple of weeks using an e-cargo bike with that system I started hating it because in practice I was NEVER on the right gearing but rather always fiddling with the twister shifter to try and find it. So to me it has definitely no advantage above stepped systems, derailers or standard hubgears even more so adding its premium price.
How much does the derailleur setup weigh? I’m tired of this weight argument. I weigh 75kg. Someone who weighs 90kg could ride the derailleur version. And when the bike is 30kg, it makes no appreciable difference at all. Especially considering the massive benefits it provides.
Thanks Court and Chris for great discussion. It really clarified my understanding, thus helping my decision to go ahead and purchase a manual shifting NuVinci rather than automatic. Really found all the technical info valuable....Court, no apologies necessary! Very helpful throughout.
Ratio span of 10-38 is equivalent to 11-42. That makes it easier to compare to tradional sprockets. A rear gear cluster of 11-42 has the same ratio span as the Enviolo.
Thanks for the conversion there Mark! I was saying 10-38 but your 11-42 is an actual gear range (or much more common). I'll try to use that in the future :)
I have mixed feelings about the CVT hubs. I don't do electric so my experience is purely from normal riding. I owned a N360 while it was still just fallbrook tech (likely around 2012 or so). The hub felt like it was filled with tar. Pedaling had a feeling of drag in the hub. Hills I used to climb daily with my shimano 3 speed and 8 speed now required me to walk up the hill. It was not a gearing issue, but one of efficiency. The lowest "gear" on the nuvinchi was far lower than the two IGH hubs I had. So it should have been easier. The hub also after about a year developed a leak. After about a year of leaking it stopped. Then a few months or so after that it developed the dreaded death rattle. So needless to say I am hesitate to buy another. What was nice about the hub was shifting was smooth and you could quickly dial in the best ratio for the condition. Though you could not fully adjust your gearing at a red light as a regular IGH can. The fact I also did not have to worry about gears slipping or getting stripped was a massive bonus and one of the main reasons I did not replace the hub sooner. So on the one had the hub has some rather big pluses on it#s side. But it also has a lot of negatives. Especially as fallbrook will not release efficiency data and simply claims third parts tests of under 80% are wrong. Perhaps if they would be more honest and also fix some of the hubs issues I would buy one again. But I can not recommend them as is.
Well, the way it works is that there are two discs inside and a bunch of balls on individual axles that act as the planetary gears. The speed changes as a result of the angle of the axles of the balls changing, which changes the contact point on the discs and thus the gear ratio. The issue with this is that it relies on the "friction" of the fluid inside the housing to keep these balls from slipping, while still allowing them to "roll" on the contact surfaces. So your assessment that it felt like it was filled with tar is not as far off as you think... Also the difference in gear ratio is not as evenly spaced, because the diameter of the planetary "radius" changes a bit more drastically even if seamlessly.
I have a bike with the NuVinci N360 hub. I'm interested in converting the bike to electric drive. The bike also has Gates belt drive. The Bafung dealer tells me this mid-bike motors do not work with Gates belt drive. (They wouldn't tell me why not). Is there an add-on electric motor that works with the NuVinci hub and Gates belt?
I love the idea of the cvt and most aspects of it, but I’m turned off by the lower efficiency. If someone made one that was closer to 90% than 80% efficient, I’d get one. I did recently read that efficiency was greatest in the middle gears, but I don’t know how great. I’m wondering if I might get a larger chain ring so I can mostly use the middle “gears” and still be going 20 mph, which is my usual speed. Any details about cvt would be great!
Great review again. You really should check out the new Pace Series by Koga. They offer exactly this system on their sporty commuter bike, aswell as the really great functioning Steps e8000 DI2 system. Not to mention the Koga E- world traveller with the Rohloff e-14. I'd be happy to bring you in contact with these guys.
In my experience with a 12-36 rear cassette and mid motor a 10-38 ratio would be plenty for the steepest hills on pavement and almost everything off pavement. I have been really tempted to get the N380 but can't quite justify the money, yet. This one you've reviewed looks hard to beat for a near perfect cruiser with the addition of a seat suspension of course.
Why don't they pair this with a planetary geared bottom bracket? You could run a thinner belt/chain and a lighter geared hub by turning the low speed & high torque of your cranks into high speed & low torque that only gets converted back to low speed & high torque by a final drive planetary set in the hub. Lighter hub and chain means less unsprung mass and less chain slap for mountain bikes.
Thanks for this review. You gave good insight into this CVT and clarified the SE functionality. I just changed my Wish List of parts for my new, home-built e-bike. I will order the SE version. Given manufacturers tend to design their bikes to meet European standards (250-350 watts), DIYers like myself are building much more powerful bikes with Bafang and Tong Sheng motors, for example. I wanted to use NuVinci N380 technology but was initially concerned it would not be able to handle the added torque. Your review helped alleviate that concern by highlighting the torque rating for the N380 SE @ 100 + NM. Another 'read' from today discussed how to reprogram the Bafang controllers to reduce the motor torque lightening the load on the CVT. I think my rebuild goals are firming up...with NuVinci still in the mix.
The Rohloff you can actually buy and install yourself, but it's very expensive. The Enviolo you can't, I've tried to contact them via email and get one, and they said they only sell to OEMs. I wonder if I tracked them down and threw suitcases of money at them ("take my moneeeeeeeey!") if it'd be more likely that they'd (1) actually sell it to me or (2) got a restraining order? :)
Garen Parham the Enviolo is also available as an aftermarket product. There aren’t many out there yet, but you can find plenty of Nuvinci hubs available as aftermarket parts.
used a 360 on my eb for about 11 months before it failed, I have a cyclone setup, would have been fine for a standard 750 watt it would have held up fine. Now using an old 171 3 years now without fail.
and NuVinci is not selling traction fluid so you can refill/replace your hub. Due to that you can not repair it. And leaking hubs from them is not something new...
I think the eMountain bikes will eventually go to this, I want you review that Rholoff eMTB at interbike, I'm interested to see how well that works especially with the belt drive system. Keep up the great work that you do Court
I really appreciate all the data you have supplied me in my search for a new ebike. I’m sold on the maintenance side of the cvt/belt drive but a little worried about the not shifting while pedaling aspect. My question is can I decrease my input but not stop pedaling change gears and then pedal hard again? I think I need to go test ride a cvt because I’m just so used to gears.
We have many of our customers operating this in snow and cold weather with no issues. Most of the bikes we sell with this drivetrain have a belt as well which is ideal for the snow since you don't have the same rust or corrosion issues as with a chain and derailleur.
Nice explanation and technical details of Vario versus Cassette. For me, seems the Vario would be best for a mostly flat city commute application and a cassette would offer more enjoyment with precise shifting, especially on hilly terrain. A very helpful review as I’m considering purchasing the R&M Culture which is available with either the Vario or Cassette, in USA $590 more for Vario on the Culture. Thank you Cort, always excellent reviews!
Though my recollection of derailleur shifting is that I often chose a suboptimal gear because of the many gears that overlapped or were unequally spaced. The Rohloff or Enviolo would prevent that of course. What I have found with Enviolo’s turning shifter is that it takes several movements of the wrist to go from top to bottom ratios and therefore it is far from instantaneous. This was most apparent when coming off a fast and steep decline followed immediately by a steep incline.
@@johne6081 indeed, I’ve just paid £450 to change an Enviolo sprocket to lower my ratios. Something that might have cost me £50 with a derailleur system.
@@petergilbert72 I build up my own cassettes and freewheels and choose my own chainrings to provide either half-step, 1.5-step, or crossover gearing, with a 5 to 7 percent progression between ratios. I use conventional linear-action shifters, either barcons, downtube levers, or, on the mountain bike, "thumbies," always in so-called friction (nonindexed) mode, and I can always find a suitable gear quickly and effortlessly.
I am looking for an aftermarket internally geared rear wheel hub for my 1000 W belt driven bicycle. As the Internally geared hub that came with it from China is garbage. Can you recommend an easy to install quality product thank you.
The efficiency of the NuVinci is the biggest problem and is the issue with all spherical ball drive transmissions. They HAVE to pump fluid away from where the balls make contact. Think how your tires have to displace water away from your tires. The only way to increase the efficiency is to decrease the speed. The only way to do that would be the make the unit much larger because the ball contact friction is limiting the torque. All in all it's not worth it unless you have a serious aversion to indexed shifters. Personally, I have a problem imagining the galling of the spheres and races that would happen if the fluid or forces were just a LITTLE bit off. Give me a straight tooth geared transmission and some form of active noise cancelling or a better designed transmission ;)
The advantage for me was in the ability to change gear ratios during a standing stop by simply dialing it in. If I'd known the 380 was only rated for 250 watts I would have given some thought about opting for a 9 gear cassette in the rear. I originally ordered a Catrike recumbent trike with the Nuvinci 380 hub/derailleur and a BBS02 750 watt motor pedelec assist/ and switched manual no assist for use on the flats. It has worked well (3 yrs) until now; this Covid plandemic has kept me grounded for the past four months. The dealer left out the part where the 3x max wattage rating voided the warranty, though I can't put the blame on him. It's doubtful I would have changed a thing. Now after sitting, the trike's acting like the hub's filled with gravel. Just a SWAG (scientific wild-assed guess) but I'm betting there's no fluid left inside the hub and no way to fix or replace the fluid? I'll have to call Utah Trikes in the morning.
Hi Court and thanks for this. And now you got me thinking. I'm a fan of and have owned and used IGH systems quite a bit. I know Shimano has had an automatic option with the steps system that integrates with Di2 Alfine kit for some time now. I saw at Interbike 2018 Bosch mentioned they would support that too staring in 2018. Have you seen or tried any of these? I have a bike with a steps drive that supports it and was thinking of building up a wheel with Alfine 11 Di2. I'm also getting a Benno with a new Bosch CX drive that should support it and am thinking I might want to do the same there. On steps (at least on mine) one can relatively easily switch between manual and automatic shifting. I haven't got to play with a Bosch CX yet so I don't know what the automatic shifting options are, if they come with it "out of the box" like steps or if this would require a firmware update. Do you have any experience on this? Thanks!
"- Sometimes, the Enviolo NuVinci system can feel sluggish or soft when pedaling and I've been told that there is a break-in period of ~500 miles where it may not be operating at optimal efficiency..." What's the efficiency rating i.e. power loss after break-in period?
I've read the power losses are about 12 to 15% at the extremes (full low or full high) but this decreases to 4 to 5 percent at the 1:1 center position. I have the NuVinci 380 on my 2017 R&M Delite GT, and yes, there is a break-in period. I at first tried shifting under load, but quickly learned to ease up on the pedal force while shifting. It soon becomes second nature.
You cannot expect exact efficiency data of the NuVinci system as compared to the Rohloff steel-on-steel gear cluster. We are dealing with fluid dynamics with the NuVinci, and it is much more influenced by environmental conditions; was the bike parked in extreme heat or cold? I always park my bike in my conditioned garage, so I cannot offer any data as to this.
State the ratings at some constant conditions, temp, humidity, etc ... or better yet provide a graph of ratio vs. efficienct with multiple lines each at different ambient temps ... that's common practice.
@@zoomev3023 They will never provide exact efficiency numbers. I used to work there, I know exactly what they are, and I can't tell you either or they'll sue me. I can tell you this much which is based on my personal experience and not my inside knowledge; I have one on an electric assist bike and it's great. On my 'regular' bikes I've tried it and decided it wasn't for me.
Yes, our mechanic in Helsinki reports that these aren’t the best in very low temperatures. Apparently still works but harder to shift and possibly some extra rolling resistance, but could be wrong about that.
Thanks for the review, I'm researching what to buy as bikes are expensive. Does it feel sharp from the start? I have driven CVT cars and hate them, feels like a soggy elastic band from the lights. I do love the concept of no maintenance. My traditional mountain bike is clunky and I sometimes forget to change down quick enough before I come to a stop.
CVTs don’t need to be soggy. They are designed this way to allow engine to come up to speed before the “gearing” increases. This maximises efficiency. Some CVT boxes have paddle shifts which makes it act like a normal gearbox, just at the cost of efficiency.
Another informative review, thank you. You choose such nice locations for your reviews would it be possible to describe where you are and maybe some information on your location? For example is that a designated bike path, or do you share it with pedestrians? Thanks
If you want an ebike and don't plan to do much work - basically just pedaling because it's mandatory (in Germany) - what would be the easiest solution? Electric cars and motorbikes do fine without gears, so does a fixie with a motor make sense here?
I think you mean single speed instead of Fixie.. Problem is cadance. Since this system needs force on the pedals, because of the torque sensor, you would not be able to put enough force on the pedals to keep the motor running at high cadance. What your looking for is a bike with just a cadance sensor, but this not offered on bikes with a high end drive system like Bosch CX.
Good post Court. I bought an R & M Nevo from Sam in Fullerton 7 months ago. I have only one concern, and you almost hit on it. Fallbrook Technologies filed Bankruptcy (The Mfg's of NuVinci Technology CVT Bike Transmission) Court can you comment further on the stability on where this company stands today (other than just re-naming the NuVinci Trans?) I love everything about my bike, and I want to buy a 2nd R & M For my wife (NuVinci Equipped) But the Fallbrook bankruptcy has me concerned. Keep up the good work my friend.
Fallbrook has transitioned through Chapter 11 and is now in a stable position with plenty of financial support. The financial trouble was related to licensing deals which take a ton of resources but can often take a long time to pay out. They're working with several sizable companies, including Continental. They have divided out that section of the company so their bike sector which is very strong can grow on its own without the financial pressure of their licensed technology projects. I hope this helps.
HI Man, not sure if you get Merida bikes in the USA, but I just got a Espresso E800, it runs a DI2 on a Alfine 8 speed, this bike cost me 3200 in Australia and its a great bike to ride, could you ride one? they are great for the price point
I'd like to get a bike for commuting 10-15 miles each way total 30 miles max without recharging. Suburban commute. I'd like it to travel at least 20 mph. I'm 6 foot and weigh 215 lbs. it would be parked in a covered exterior train station. Would like to spend under $1500.00. Also a batter that's built in would help it from being robbed. Any advice from anyone would be appreciated.
Under $1500 is tough... If you can save up to $2000-2500, you can get an entry level Bosch/Yamaha system, which will almost certainly last you longer than the cheaper systems and will be generally more enjoyable. Also, for theft, you're much better off getting one you can bring with you; without the battery, your ebike is just an absurdly heavy bike. Plus with that distance you're going to need to charge it before each leg unless you ride at the minimum assist (harder to meet your 20 mph+).
The Nuvinci system is great....... but make sure your battery is loaded. When you battery is empty it feels like riding uphill all the time. Nuvinci is not available on non electric bikes and that's for this reason. Without power your pedalling feels like driving through syrup.
I'd say that is an exaggeration. I have been riding an n360 on a (non-E) bike for 5 years with no problems. There is a loss of efficiency toward the low end of the gear range, apart from that it is much like any other hub gear.
Do you mean that the Enviolo responds differently to motor power setting zero from the battery literally being dead? I have a new R&M Tinker and I turn the battery power to zero to get exercise and extend range. On an experimental ride I ran the battery until it ceased to provide motor assistance but it still powered the lights and the walk mode. I didn’t notice any ‘syrupy’ feel and found the bike quite easy to pedal with leg power alone on gentle hills/flat asphalt.
Finished my solarized walk assist device. Watch on utube, Solarized walk assist device - camper build Also, Solarized walk assist device. Solarized walk assist device gets 200km/day. Haven't tested the camper for distance, hoping to get 200km/day. I can boil water, charge cordless tools, haul materials or just ride for fun. The camper's lining is pressure fit, so it can be collapsed onto the deck to decrease drag. Also watch on utube, Solarized walk assist device - morning coffee. Check it out.
I feel ya Edwin... many of the competing step-thru products on the market suffer from frame flex. R&M overbuild their bikes with these strong boxy tubes and simplified paint jobs. Maybe it's an acquired taste ¯\_(ツ)_/¯
How much does the derailleur setup weigh? I’m tired of this weight argument. I weigh 75kg. Someone who weighs 90kg could ride the derailleur version. And when the bike is 30kg, it makes no appreciable difference at all. Especially considering the massive benefits it provides.
Hi Chris, you've made an excellent point. Relative to the weight of the bike and rider + gear, the additional weight of a CVP or internally geared hub doesn't make a material difference. It does contribute to unsprung weight, like on the R&M Delite, Culture, and Homage, but it's still not too bad. We're talking about a derailleur + cassette at 0.68kg vs. Enviolo NuVinci at 2.49kg hope that helps
Yeah very true, i have had a nuvinci hub for 3 years, it never broke, and works perfect under load with a cargo bike, no other hub can do that, no matter the weight.
@@ElectricBikeReview I was wondering if maybe you could help me out by chance? I've got a Nuvinci N171 hub on the way, and it's threaded for a freewheel, but I'd like to get a fixed 22 tooth sprocket/cog/gear for it that screws directly to the freewheel threads (Or however that works, I'm new to this and not sure). The problem is that I'm not sure of the terminology to use in searching for one, so I thought I'd ask someone experienced so I don't accidentally order the wrong thing. Whether you decide to respond or not, thanks either way.
Let me add a praise for this transmission. I bought an Nviolo a year ago. I put a TDZS 350watt motor on my bike, but I had 2 years of wear on the derailer which did not want to continue to operate on the 6 or 7 top gears. The chain would jump or even pop the chain link. With the Nviolo I do not have chain problems and I can always find a gear ratio for current performance needs. 6100 trouble free miles for the year.
I bought one of the ancient first generation NuVinci hubs, way back in around 2006ish. I spoked it myself, tensioning it by plucking the spokes till they all "sounded" and "felt" right. It was paired to a rusty old Huffy 314 with magenta mountain bike handles and an inverted set of speed handlebars... It was truly Frankenstein's bicycle... But I loved that bike. I rode it till I cracked the frame (broke the main crank bearing off the seat downtube, and started cracking the rear fork). I was gonna weld it, but then the bike got run over... I still have the mangled mess in a storage shed, NuVinci still intact, fortunately... My little hill guy cracked, but it still works.
I'm a decade older now, and a little more creaky... Maybe I could fit that hub to something like a comfy recumbent someday...
will you send me that hub?
One thing that I'd like to mention in regards to not just the Enviolo hub but other internally geared hubs is how the wheel is laced when compared to a conventional cassette setup.
If you imagine looking at a bicycle from the rear, you'll notices that the spokes are offset on a bike featuring a conventional cassette and derailleur. Essentially, the relationship between the hub, spokes and rim forms an acute triangle. This results in a lot more stress being put on the spokes on the cassette side. This makes the wheel significantly weaker and more prone to buckling. On older, less well maintained bikes, spokes invariably break on the cassette side of the wheel.
When viewed from the rear, you'll see that the relationship between the hub, spokes and rim on an internally geared bike form an isosceles triangle with the tensile stress evenly distributed across the left and right spokes. This makes the wheel much stronger.
In my opinion, it's worth consideration if you are a heavier rider or if you plan on carrying a considerable amount of weight in your panniers.
Interesting...good info.
currently researching for a long term bike. I am big and tall so this is very helpful. very well explained as well. thank you :)
I'm just relieved Nviolo is still around and better than ever after a shake-up at the company in the past couple years! What a vote of confidence being on bike share, needing no internal maintenance, and Chris vouching for their reliability over years with his customers!
Integrating it into the motor is a great idea but I won't care unless that motor is QUIET like the Bafang one rather than the obnoxious Bosches. I wish there were a glut of Bafang, Nviolo, Gates belt, front suspension, fixed front rack, integrated lights bikes rather than it all being Bosch. I LOVE Bosch's system but that motor noise KILLS me.
Your tech talk is the heart of your vids, Court, so no need to apologize! Fantastic overview comparing all the different specs' pros and cons, with likely applications and in-the-field insights from Chris based on his clientele's experiences.
I've been riding a Gekko FX trike with a Nuvinci for about 4 years now, and I absolutely love it! I'm 70, have fibromyalgia, asthma, and COPD - I'm a slowby all around. I chose the Nuvinci in order to choose my "speed" minutely, and it has absolutely met my expectations. I also have a super granny on the front (22 tooth) that I added to the regular 2 sprockets rather than down-gear all 3, and they work out very well. I went to Morro Bay this week, and while I had to pedal-rest-pedal-rest, I did make it up the nice, steep hill. (I live in the flat side of Bakersfield - not a lot of hills here.) I'm working on getting into better shape now that the air quality is better - had to stop riding with the Calif fires - covid has been a godsend to the asthma - I've been able to start riding again! Hooray! Anyway - thanks for a great product with the Nuvinci!
I was also thinking about getting the enviolo for my ebike paired to a befang motor. I also live in Bakersfield.
My wife has the Nuvinci 360 on her Workcycles Secret Service. After 5 years and 3,000 miles, the Nuvinci hub has never required any maintenance whatsoever. Even the shifter cables have never needed adjustment.
Plus, like with any IGH, the chain, chainring and cog last way longer than a derailleur set up - since the chain can be wider (therefore the ring and cog are both thicker metal - and wear slower).
The drawback to an IGH like the Nuvinci is the chain must have a mechanism to adjust chain tension, such as an elliptical bottom bracket or chain adjusters in the rear drop out. Both add some complexity to pulling the rear wheel to fix a flat. That said, I have found the Nuvinci hub itself is not hard to disconnect from the shifter cables to pull the rear wheel.
I just got into biking like a month ago, riding upwards of 15-20 miles a day. I'm saving up for a Priority Continuum Onyx (Enviolo hub, belt drive, but not electric-I'm not into it). I've been riding a borrowed WalMart bike-something new breaks every week. Can't wait for my own sturdier, nicer bike.
Great choice on your part. That a great value. 👍👍👍
@@stoutdog56 Thanks. Of course, now I’ve had it for a while and love it to death.
I have been using the NuVinci harmony on my electric bike for a year now, love it fully automatic and no hassle
Okay now i get it, internal hub shifting is like driving a manual clutch stick shift where you ease off the gas to clutch shift.
Internal hub shift just ease off the pedaling and shift at the top/bottom of the pedal stroke! 👍
Brilliantly explained
@@MrPillowFoot thank you. Have Alfine8 on Kalkhoff Integrale, its so much better to ride now with timing my shift without false shifting. Almost like mx5
I like the detail that EBR goes into for the overview It must be nice for professional riders. But for beginners like me it's very hard to tell how this bike stacks up vs it's competition. I wish you would compare it with other bikes in it's price class and let me know how it stacks up. Unless I am very technical on bikes after watching an EBR I don't know whether or not this bike is a good value. This is very important we are talking about a very big purchase.
I'm 77 retired and love the quality of your bikes. Here in the beautiful Napa Valley they are developing trails for jogging or walking and now I see e bikes more every day. I will by a E bike but the selection you have are peddle only that won't work for me. Come on guys I want one of your great bikes but not untill a throttle model. Give us old guys with bad knees. Have a great day.
As Chris pointed out in the video, it seems Cort hasn't been shifting correctly & that's why he says it's hard to shift.
On this system, you can create an automatic transmission. It will be just an explosion in the bicycle industry. It is only necessary to install a sensor that measures the angles of inclination and speed, a controller that will control the servo drive that tensions the cables and changes speeds in auto mode.
It's already here.
You don't have to back off when shifting. The hub will shift fine during the dead spots in your pedal stroke. Acceleration is one of the things I love about having a CVT.
Maybe that's because it's an E bike, it looks like the motor torque is too much and interferes with the shifting
@@ahmeeeeeeeeeeeed I'd not considered that but obviously motors generate continuous torque so don't give the hub a chance to shift.
I built 2 ebikes with banfang fun 8 crankdrive motors and N360 hubs with harmony electric shifting.
Mine is mated to the BBS2 750w motor and has always worked well
My wife's bike is a BBS1 350w hers regularly loses the autoshifting function resulting in rapid peddling stuck in low gear, she has to stop and do a reset to get it working again, something I have not been able to solve.
Having first ridden my bike with manual shifting which feels stiff under load I think the harmony system works better, if I use manual mode the twist shift is very light to use and would suit people with weak hand grip.I never need to lift off the peddling pressure the shifting is buttery smooth, when I had the BBS1 set up with derailuer gear system shifting could be quite harsh and jerky I felt the derailuer and chain wouldn't have lasted very long.
It's fun to ride my 750w in manual mode using the throttle gently to avoid front wheel lifting and get moving to a fast walking pace then rolling on the shifter it actually feels like a throttle giving smooth rapid acceleration up to 28 mph, also running between half and full power on the thumb throttle you can speed up and slow down using the gear shift in manual mode it's good fun off road.
This is absolutely wild, automatic CVT on a bike!
As every hubgear the Enviolo is safe from damage and low on maintenance. Right. But the argument that it allows being on the right gearing all the time is not that real. After a couple of weeks using an e-cargo bike with that system I started hating it because in practice I was NEVER on the right gearing but rather always fiddling with the twister shifter to try and find it. So to me it has definitely no advantage above stepped systems, derailers or standard hubgears even more so adding its premium price.
How much does the derailleur setup weigh? I’m tired of this weight argument. I weigh 75kg. Someone who weighs 90kg could ride the derailleur version. And when the bike is 30kg, it makes no appreciable difference at all. Especially considering the massive benefits it provides.
Not many concepts get to this stage. Congratz!
Thanks Court and Chris for great discussion. It really clarified my understanding, thus helping my decision to go ahead and purchase a manual shifting NuVinci rather than automatic. Really found all the technical info valuable....Court, no apologies necessary! Very helpful throughout.
Why do they call the gear ratio spann in degrees? Should it not be percent?
Great review. Seeing two experts play off each other’s knowledge Maybe you and Chris do more together.
You do a great job I thank you for this! Please keep it up! You need a TV series about utilitarian cycling….do it!
Ratio span of 10-38 is equivalent to 11-42. That makes it easier to compare to tradional sprockets. A rear gear cluster of 11-42 has the same ratio span as the Enviolo.
Thanks for the conversion there Mark! I was saying 10-38 but your 11-42 is an actual gear range (or much more common). I'll try to use that in the future :)
I have mixed feelings about the CVT hubs. I don't do electric so my experience is purely from normal riding. I owned a N360 while it was still just fallbrook tech (likely around 2012 or so). The hub felt like it was filled with tar. Pedaling had a feeling of drag in the hub. Hills I used to climb daily with my shimano 3 speed and 8 speed now required me to walk up the hill. It was not a gearing issue, but one of efficiency. The lowest "gear" on the nuvinchi was far lower than the two IGH hubs I had. So it should have been easier. The hub also after about a year developed a leak. After about a year of leaking it stopped. Then a few months or so after that it developed the dreaded death rattle. So needless to say I am hesitate to buy another.
What was nice about the hub was shifting was smooth and you could quickly dial in the best ratio for the condition. Though you could not fully adjust your gearing at a red light as a regular IGH can. The fact I also did not have to worry about gears slipping or getting stripped was a massive bonus and one of the main reasons I did not replace the hub sooner.
So on the one had the hub has some rather big pluses on it#s side. But it also has a lot of negatives. Especially as fallbrook will not release efficiency data and simply claims third parts tests of under 80% are wrong. Perhaps if they would be more honest and also fix some of the hubs issues I would buy one again. But I can not recommend them as is.
Well, the way it works is that there are two discs inside and a bunch of balls on individual axles that act as the planetary gears. The speed changes as a result of the angle of the axles of the balls changing, which changes the contact point on the discs and thus the gear ratio. The issue with this is that it relies on the "friction" of the fluid inside the housing to keep these balls from slipping, while still allowing them to "roll" on the contact surfaces. So your assessment that it felt like it was filled with tar is not as far off as you think...
Also the difference in gear ratio is not as evenly spaced, because the diameter of the planetary "radius" changes a bit more drastically even if seamlessly.
Very informative! Thank you Court and Chris from Propelbikes.
I have a bike with the NuVinci N360 hub. I'm interested in converting the bike to electric drive. The bike also has Gates belt drive. The Bafung dealer tells me this mid-bike motors do not work with Gates belt drive. (They wouldn't tell me why not). Is there an add-on electric motor that works with the NuVinci hub and Gates belt?
I love the idea of the cvt and most aspects of it, but I’m turned off by the lower efficiency. If someone made one that was closer to 90% than 80% efficient, I’d get one. I did recently read that efficiency was greatest in the middle gears, but I don’t know how great. I’m wondering if I might get a larger chain ring so I can mostly use the middle “gears” and still be going 20 mph, which is my usual speed. Any details about cvt would be great!
CVT strikes me as a [non]solution to a non-problem.
Great review again. You really should check out the new Pace Series by Koga. They offer exactly this system on their sporty commuter bike, aswell as the really great functioning Steps e8000 DI2 system. Not to mention the Koga E- world traveller with the Rohloff e-14. I'd be happy to bring you in contact with these guys.
In my experience with a 12-36 rear cassette and mid motor a 10-38 ratio would be plenty for the steepest hills on pavement and almost everything off pavement. I have been really tempted to get the N380 but can't quite justify the money, yet. This one you've reviewed looks hard to beat for a near perfect cruiser with the addition of a seat suspension of course.
Did you ever take the plunge on the N380?
The N380 had a limited range of shifting when stopped. Wondering if this Enviolo has corrected that limitation? Anybody know?
Why don't they pair this with a planetary geared bottom bracket? You could run a thinner belt/chain and a lighter geared hub by turning the low speed & high torque of your cranks into high speed & low torque that only gets converted back to low speed & high torque by a final drive planetary set in the hub. Lighter hub and chain means less unsprung mass and less chain slap for mountain bikes.
Do u have to have a ebike with that rear hub curious on that plan to watch the video latter this evening
Yeah, it’s chuckles from Propel Biles! Such a happy soul.
Thanks for this review. You gave good insight into this CVT and clarified the SE functionality. I just changed my Wish List of parts for my new, home-built e-bike. I will order the SE version. Given manufacturers tend to design their bikes to meet European standards (250-350 watts), DIYers like myself are building much more powerful bikes with Bafang and Tong Sheng motors, for example. I wanted to use NuVinci N380 technology but was initially concerned it would not be able to handle the added torque. Your review helped alleviate that concern by highlighting the torque rating for the N380 SE @ 100 + NM. Another 'read' from today discussed how to reprogram the Bafang controllers to reduce the motor torque lightening the load on the CVT. I think my rebuild goals are firming up...with NuVinci still in the mix.
The Rohloff you can actually buy and install yourself, but it's very expensive. The Enviolo you can't, I've tried to contact them via email and get one, and they said they only sell to OEMs. I wonder if I tracked them down and threw suitcases of money at them ("take my moneeeeeeeey!") if it'd be more likely that they'd (1) actually sell it to me or (2) got a restraining order? :)
Garen Parham the Enviolo is also available as an aftermarket product. There aren’t many out there yet, but you can find plenty of Nuvinci hubs available as aftermarket parts.
@@newschoolnerd Where? Have looked quite intently, and never could find anything. Manufacturer couldn't help me either, so finally just gave up.
For instance in Belgium since January, local sell and repair shops have access to the supply.
Thank you sir. I’ll go with rohloff
used a 360 on my eb for about 11 months before it failed, I have a cyclone setup, would have been fine for a standard 750 watt it would have held up fine. Now using an old 171 3 years now without fail.
and NuVinci is not selling traction fluid so you can refill/replace your hub. Due to that you can not repair it. And leaking hubs from them is not something new...
awesome video thanks!
You’re welcome! Glad you enjoyed it!
I think the eMountain bikes will eventually go to this, I want you review that Rholoff eMTB at interbike, I'm interested to see how well that works especially with the belt drive system. Keep up the great work that you do Court
Thanks for your useful information!!
Wholesome, solid video.
Good stuff🤙 future is bright
gotta ware shades
I really appreciate all the data you have supplied me in my search for a new ebike. I’m sold on the maintenance side of the cvt/belt drive but a little worried about the not shifting while pedaling aspect. My question is can I decrease my input but not stop pedaling change gears and then pedal hard again? I think I need to go test ride a cvt because I’m just so used to gears.
I am not willing to give up control over my gear ratios as I ride.
what powers the gear chang? What decides when to change?
how does it work in snow and cold weather?
We have many of our customers operating this in snow and cold weather with no issues. Most of the bikes we sell with this drivetrain have a belt as well which is ideal for the snow since you don't have the same rust or corrosion issues as with a chain and derailleur.
Fuck yeah!!! Another great review
Nice explanation and technical details of Vario versus Cassette. For me, seems the Vario would be best for a mostly flat city commute application and a cassette would offer more enjoyment with precise shifting, especially on hilly terrain. A very helpful review as I’m considering purchasing the R&M Culture which is available with either the Vario or Cassette, in USA $590 more for Vario on the Culture. Thank you Cort, always excellent reviews!
Though my recollection of derailleur shifting is that I often chose a suboptimal gear because of the many gears that overlapped or were unequally spaced. The Rohloff or Enviolo would prevent that of course. What I have found with Enviolo’s turning shifter is that it takes several movements of the wrist to go from top to bottom ratios and therefore it is far from instantaneous. This was most apparent when coming off a fast and steep decline followed immediately by a steep incline.
@@petergilbert72 I have no motivation whatsoever to abandon my conventional sprocket-and-chain transmission.
@@johne6081 indeed, I’ve just paid £450 to change an Enviolo sprocket to lower my ratios. Something that might have cost me £50 with a derailleur system.
@@petergilbert72 I build up my own cassettes and freewheels and choose my own chainrings to provide either half-step, 1.5-step, or crossover gearing, with a 5 to 7 percent progression between ratios. I use conventional linear-action shifters, either barcons, downtube levers, or, on the mountain bike, "thumbies," always in so-called friction (nonindexed) mode, and I can always find a suitable gear quickly and effortlessly.
I am looking for an aftermarket internally geared rear wheel hub for my 1000 W belt driven bicycle.
As the Internally geared hub that came with it from China is garbage.
Can you recommend an easy to install quality product thank you.
The efficiency of the NuVinci is the biggest problem and is the issue with all spherical ball drive transmissions. They HAVE to pump fluid away from where the balls make contact. Think how your tires have to displace water away from your tires. The only way to increase the efficiency is to decrease the speed. The only way to do that would be the make the unit much larger because the ball contact friction is limiting the torque. All in all it's not worth it unless you have a serious aversion to indexed shifters. Personally, I have a problem imagining the galling of the spheres and races that would happen if the fluid or forces were just a LITTLE bit off. Give me a straight tooth geared transmission and some form of active noise cancelling or a better designed transmission ;)
The advantage for me was in the ability to change gear ratios during a standing stop by simply dialing it in. If I'd known the 380 was only rated for 250 watts I would have given some thought about opting for a 9 gear cassette in the rear. I originally ordered a Catrike recumbent trike with the Nuvinci 380 hub/derailleur and a BBS02 750 watt motor pedelec assist/ and switched manual no assist for use on the flats. It has worked well (3 yrs) until now; this Covid plandemic has kept me grounded for the past four months. The dealer left out the part where the 3x max wattage rating voided the warranty, though I can't put the blame on him. It's doubtful I would have changed a thing. Now after sitting, the trike's acting like the hub's filled with gravel. Just a SWAG (scientific wild-assed guess) but I'm betting there's no fluid left inside the hub and no way to fix or replace the fluid? I'll have to call Utah Trikes in the morning.
Hi Court and thanks for this. And now you got me thinking. I'm a fan of and have owned and used IGH systems quite a bit. I know Shimano has had an automatic option with the steps system that integrates with Di2 Alfine kit for some time now. I saw at Interbike 2018 Bosch mentioned they would support that too staring in 2018. Have you seen or tried any of these?
I have a bike with a steps drive that supports it and was thinking of building up a wheel with Alfine 11 Di2. I'm also getting a Benno with a new Bosch CX drive that should support it and am thinking I might want to do the same there. On steps (at least on mine) one can relatively easily switch between manual and automatic shifting. I haven't got to play with a Bosch CX yet so I don't know what the automatic shifting options are, if they come with it "out of the box" like steps or if this would require a firmware update. Do you have any experience on this? Thanks!
Can you review the Yamaha urban rush soon? I am asking for a friend that wants to buy one.
"- Sometimes, the Enviolo NuVinci system can feel sluggish or soft when pedaling and I've been told that there is a break-in period of ~500 miles where it may not be operating at optimal efficiency..."
What's the efficiency rating i.e. power loss after break-in period?
I've read the power losses are about 12 to 15% at the extremes (full low or full high) but this decreases to 4 to 5 percent at the 1:1 center position. I have the NuVinci 380 on my 2017 R&M Delite GT, and yes, there is a break-in period. I at first tried shifting under load, but quickly learned to ease up on the pedal force while shifting. It soon becomes second nature.
You cannot expect exact efficiency data of the NuVinci system as compared to the Rohloff steel-on-steel gear cluster. We are dealing with fluid dynamics with the NuVinci, and it is much more influenced by environmental conditions; was the bike parked in extreme heat or cold? I always park my bike in my conditioned garage, so I cannot offer any data as to this.
State the ratings at some constant conditions, temp, humidity, etc ... or better yet provide a graph of ratio vs. efficienct with multiple lines each at different ambient temps ... that's common practice.
@@zoomev3023 They will never provide exact efficiency numbers. I used to work there, I know exactly what they are, and I can't tell you either or they'll sue me.
I can tell you this much which is based on my personal experience and not my inside knowledge;
I have one on an electric assist bike and it's great. On my 'regular' bikes I've tried it and decided it wasn't for me.
Regarding this breaking period, I have not experienced this myself with the 3 new replaced hub I have got over the 10 months period.
Great video, thank you! Do you know if cold weather (like minus 20 celcius) could create problems with these systems? Thanks!
Yes, our mechanic in Helsinki reports that these aren’t the best in very low temperatures. Apparently still works but harder to shift and possibly some extra rolling resistance, but could be wrong about that.
Great review! Highly informative.
Thanks for the review, I'm researching what to buy as bikes are expensive. Does it feel sharp from the start? I have driven CVT cars and hate them, feels like a soggy elastic band from the lights. I do love the concept of no maintenance. My traditional mountain bike is clunky and I sometimes forget to change down quick enough before I come to a stop.
CVTs don’t need to be soggy. They are designed this way to allow engine to come up to speed before the “gearing” increases. This maximises efficiency. Some CVT boxes have paddle shifts which makes it act like a normal gearbox, just at the cost of efficiency.
For me it skips gears when in high pressure. Would rather have the manual shifting for fast riding, or standing while riding
This or Specialized turbo como 3.0 igh ?
Another informative review, thank you. You choose such nice locations for your reviews would it be possible to describe where you are and maybe some information on your location? For example is that a designated bike path, or do you share it with pedestrians? Thanks
Would be nice to see a review on the Multicharger vario model (the utility grey one!) :-) Thank you!
If you want an ebike and don't plan to do much work - basically just pedaling because it's mandatory (in Germany) - what would be the easiest solution? Electric cars and motorbikes do fine without gears, so does a fixie with a motor make sense here?
I think you mean single speed instead of Fixie.. Problem is cadance. Since this system needs force on the pedals, because of the torque sensor, you would not be able to put enough force on the pedals to keep the motor running at high cadance. What your looking for is a bike with just a cadance sensor, but this not offered on bikes with a high end drive system like Bosch CX.
Good post Court. I bought an R & M Nevo from Sam in Fullerton 7 months ago. I have only one concern, and you almost hit on it. Fallbrook Technologies filed Bankruptcy (The Mfg's of NuVinci Technology CVT Bike Transmission) Court can you comment further on the stability on where this company stands today (other than just re-naming the NuVinci Trans?) I love everything about my bike, and I want to buy a 2nd R & M For my wife (NuVinci Equipped) But the Fallbrook bankruptcy has me concerned. Keep up the good work my friend.
Gregg M. Plahy it's strange that he didn't mention the chapter 11 issue, which is likely the true reason for the rebranding.
Fallbrook has transitioned through Chapter 11 and is now in a stable position with plenty of financial support. The financial trouble was related to licensing deals which take a ton of resources but can often take a long time to pay out. They're working with several sizable companies, including Continental. They have divided out that section of the company so their bike sector which is very strong can grow on its own without the financial pressure of their licensed technology projects. I hope this helps.
Can you Review the new BMC Alpenchallenge AMP Cross ?

HI Man, not sure if you get Merida bikes in the USA, but I just got a Espresso E800, it runs a DI2 on a Alfine 8 speed, this bike cost me 3200 in Australia and its a great bike to ride, could you ride one? they are great for the price point

Nice technology , now if they could only make it more affordable. Pretty hard to justify when it often costs more than the bike : )
Currently the Enviolo price is a little more than the Shimano Alfine 11, but the older Nuvinci is about the same as the Alfine 8.

Great interviewer!
I'd like to get a bike for commuting 10-15 miles each way total 30 miles max without recharging. Suburban commute. I'd like it to travel at least 20 mph. I'm 6 foot and weigh 215 lbs. it would be parked in a covered exterior train station. Would like to spend under $1500.00. Also a batter that's built in would help it from being robbed. Any advice from anyone would be appreciated.
Under $1500 is tough... If you can save up to $2000-2500, you can get an entry level Bosch/Yamaha system, which will almost certainly last you longer than the cheaper systems and will be generally more enjoyable.
Also, for theft, you're much better off getting one you can bring with you; without the battery, your ebike is just an absurdly heavy bike. Plus with that distance you're going to need to charge it before each leg unless you ride at the minimum assist (harder to meet your 20 mph+).
Bafang BBS 02 or HD on the bike of your choice. Should be doable. Just dont ride WFO

The Nuvinci system is great....... but make sure your battery is loaded. When you battery is empty it feels like riding uphill all the time. Nuvinci is not available on non electric bikes and that's for this reason. Without power your pedalling feels like driving through syrup.
Thanks for pointing that out.
I'd say that is an exaggeration. I have been riding an n360 on a (non-E) bike for 5 years with no problems. There is a loss of efficiency toward the low end of the gear range, apart from that it is much like any other hub gear.
Do you mean that the Enviolo responds differently to motor power setting zero from the battery literally being dead? I have a new R&M Tinker and I turn the battery power to zero to get exercise and extend range. On an experimental ride I ran the battery until it ceased to provide motor assistance but it still powered the lights and the walk mode. I didn’t notice any ‘syrupy’ feel and found the bike quite easy to pedal with leg power alone on gentle hills/flat asphalt.

Hi Chris, you've made an excellent point. Relative to the weight of the bike and rider + gear, the additional weight of a CVP or internally geared hub doesn't make a material difference. It does contribute to unsprung weight, like on the R&M Delite, Culture, and Homage, but it's still not too bad. We're talking about a derailleur + cassette at 0.68kg vs. Enviolo NuVinci at 2.49kg hope that helps
Yeah very true, i have had a nuvinci hub for 3 years, it never broke, and works perfect under load with a cargo bike, no other hub can do that, no matter the weight.
Malloot , is the a way to see your setup before I spend my money on the wrong stuff and get stuck ?
@@ElectricBikeReview What is the distinction of "unsprung weight"? How would it be more or less impactful than "sprung weight"?
@@ElectricBikeReview I was wondering if maybe you could help me out by chance?
