@alftjin8477 it's not about how smart it is =). Every battery has a power output limit, and if you exide it voltage would drop significantly, and so it power output as well as a rule it recover after some time but you just can't get as much power as you like as long as it still have a charge
This was a super interesting watch, thanks for taking the time to explain everything in such detail to clearly outline the pros and cons of each system! 🙌
Bosch CX gen4: After a year of using this drive, I am very happy with it. I had no technical problems with it. The mobile app allows you to easily adjust the assistance programs to your needs. You can set overdose assistance if you like, but also such a very discreet one that when you exceed 25 km/h you almost don't feel the engine turning off. I am only so-so with the navigation built into the Kiox 300. Theoretically, it does what it is supposed to do, but it is far from smooth use. It needs refinement. The additional alarm/wireless "key" built into the Kiox 300/GPS tracking from Bosch is a very good additional option in my opinion, which requires the purchase of the Flow+ service in the subscription. I was only surprised that some of the statistics related to training are only available after purchasing the Flow+ service. I thought Flow+ was about security.
As a bosch gen4 owner, I am mainly interested in how all products perform over a 5yr+ lifespan, and how chain and gear wear handles more torq. Dont care about dragraces. My gen 4 almost always runs in ECO and almost never in turbo. less noise is always nice.
What's also important when buying an e-bike is the motor-battery pack warranty service because nobody wants to wait 6 months to get their bike back from the service.
im using my bosch only in turbo. every time i come back with 1-15 percent battery. my first was broken on 7k km. second was broken on the screw by frame switch 10k km.my third motor still live 9.8k km. 630wh batterys are great
just change bike evry 2 year, you absically spend less in keeping everything in place XD at least for me that i do more "downhill" style ride, rather than trail/cx/enduro jopkes aside, u def have a good point
Hello Rob. I've owned a high torque/performance bike before (Flyon 5.0). Verry heavy bike with lots of torque but still didn't get up all hills like with the PWX3 motor I own now. Too much torque weare out your equipment much faster, chains break... I've tested Pinion (Simplon bike) @ Garda and must say I was very pleased with its outcome. In '26 I definitely will get a Nicolay with Pinion...🎉 Good vids you bring out ❤. Rolando.
The concept of the Pinion MGU is the future. Combining the gearbox and motor into one unit has so many advantages. This is the first version, I'm sure it'll only improve over time.
Except this concept has been around forever (even by them) and it is JUST now becoming somewhat viable and has a LONG ways to go... and that was before the DJI came out. Any hopes they had of matching the DJI power and range with their current designs are out of the question now. They basically need to nearly start over. Going to be a tough for them, imo.
Pinion works on gearbox from over ten years... and before of that they they were into the automotive sector (Porsche) so... they perfectly know what they're doing.
How much power is enough power? I think we’re reaching the limit of what anyone needs. Personally I’d value robustness and reliability of a motor system waaaaaaaay ahead of power. Time will tell with the newcomers!!
Been thinking about this a lot recently, with all of the Amflow vids plastered over YT. Don't get me wrong it looks great fun, but I own an ebike to get further afield (and maybe tackle some fun techy sections), not bast on turbo non-stop. I rarely ever hit turbo, because its not the same sport imo. Innovation is great, but lets see it impact the prices pls.
Dji drones are incredibly reliable and have very high build quality. I would not worry about their build quality…. I would worry about their support system which would probably be not great.
@@mlee6136the demand on an MTB is far greater than the demand from a light weight drone. DJI durability is completely unknown as it relates to e-bikes.
Good review of those different units. I like the power and instant engagement of the DJI unit. I like the established reputation of the Bosch unit, it is also very quiet!. I also like the different integrated gearbox idea of the Pinion unit.
Rob, I think I’ve commented this like at least 20 times on your videos, but your channel is so good! Really appreciate the hard work you put into these
@@polska905 I use rohloff, sturmey archer, Alfine since 2005. Far better solution than any cassete based solution. For ebikes the benefits are bigger Future for ebikes is gearbox. Hub motors were mainstream and after some good mid drives motors, this is the new top level standards. Gearbox will be the same. ZF soon will show their own mgu too.
@@polska905it's a trade off. Personally the slight extra drag on my alfine 11 is easily compensated for by it's reliability and absolute silence of the belt drive.
Yes, and comparing a motor with double the power is quite weird. In the car world this would be like comparing a rally car that can not drive on roads legally, and need repairs after races because it eats parts, to a every day use road car. I would buy the bosch as i hate noise because i am old and cranky. He did a good job explaining the change they made tho. I am going to save money for it and buy one next year when this new model becomes last years model on sale:)
As an engineer and former cycle mechanic I have to say that the smaller these units get the more wear the gears will have to endure, add that to the fact that only the Pinion has a wet sump for lubrication means that the new powerful motor/drive gear units will not last - especially if they are 1000W! I'll take longevity and reliability over ultimate performance, I mean a modern skinny chain ring/cassette/chain wears fast enough without that much power trying to destroy them 🙄. Also the quiet factor of bombing a rough downhill on a silent belt drive vs some gearbox noise uphill is worth it in my books.
As a none engineer, we all know technology improves, materials improve. An F1 gearbox handles 1000 bhp. Materials 20 years ago may have reliable issues but not today.
@@kl9518 sure there is some progress in materials but not as much as people think or hope. However your formula 1 example is a bit strange as the cars in 1988 F1 had about 1500bhp and the current ones only have 1000bhp. So when materials where already good enough for 1.5 times more abuse then they get now that proves nothing at all. The reason for reduction in power in F1 is due to stricter rules. As F1 became too dangerous and had more incidents that did not end well in those days.
@@chinesepopsongs00 Ermm, material science has actually come much much further than you would imagine with far more exotic materials available for consumer goods than ever. And gearboxes in F1 cars now are more compact and engineered to much higher precision than those in the 80s ever could be, and could easily be engineered to handle 1500 bhp if they were required to.
The DJI looks great. It’s a fantastic motor. Objectively more powerful. Unfortunately there’s not many service centres in my country. Only a couple stores are authorised centres. There’s not many in the US even. I love to see the competition, but until you can walk into any bike shop and buy the DJI and have it serviced there, it’s merely a very cool novelty. That’s the massive issue that nobody is talking about. Regardless though, I really love to see this competition. It’s fantastic.
I ride a Trek Rail with an 85nm Bosch, and a Haibike XDuro Yamaha before. I just wanted a little help, not a lot, up the hill now that I'm older & fatter with problem knees but that DJI 120nm is very tempting.
Incredible performance from DJI but as you said Rob it’s part of the story still lot of unanswered questions such as reliability, water ingress etc plus how the bike rides some people won’t want all that power and I still think people will plump for the Bosch due to the options of bikes out there using the motor but credit where credit is due DJI have knocked it out of the park with the whole package, just make sure you have a back stock of chains and cassettes as you will burn through them in no time 😂 great review though Rob 👏
The DJI and Pinion MGU setup together would be the go for power and durability. Chains and cassettes are expensive and will surely offset the extra cost of a gearbox over time.
Dji has a great reputation for quality and reliability for their drones. I'm sure it will be the same this bike. China makes some of the best products in the world today.
Very nice test, but what I'm really interested in is how the downhill performance of the DJI compares to the Orbea? A powerful motor isn't everything if the rest isn't right. A comparison would be really cool.
Great balanced review Rob! DJI definetely takes the win here, with the power it provides the rattling noise seems like a minor issue..plus a really good build! would love to get my hands on it one day!
Far from balanced, take a step back and you’ll notice the test was perfectly setup for the DJI to shine, do you think it was coincidence that the test was 30 seconds when the boost on the dji was also 30 seconds.
Have you had the chance to ride the ZF system? I waited, and am super interested in the DJI system when I saw it announced earlier this year. great job again.
The dji has a 2 year warranty, like any other quality brand out there. They have selected only a few quality retailers to supply and support their product. This is already a hugely significant manufacturer of quality and reliable products, used throughout this format and many others. Obviously they have done their due diligence with research, development and marketing, with regarding their project. They have built a bike from scratch to showcase their abilities. This alone is incredible. A new bike and motor that simply blows everything existing away. I'm sure they will support this and grow what they have done. A trail bike again makes far more commercial sense than a full fat Enduro. More people ride trail bikes than anything else in this sector. I've ordered one and can't wait. I have no concerns over both reliability or support 👍😊
@@fofopads4450 not sure about ordering from the Amflow site? I've ordered mine and paid the deposit from a local approved stockist, with allocation due between Oct and Dec 👍
11:59 Regarding the “fully integrated battery” on the Bosch. This isn’t a “Bosch thing”. It’s specific to that bike model. Most Bosch bikes have a removable Powertube. The manufacturer can use either one. It’s up to you to choose a bike with the battery that you need.
I remember when it took skill to ride around on a penny farthing. Then along came these contraptions with pedals/brakes/gears/shocks and no one needed any strength or skill...😂
I really hope the other brands now start thinking of developing their USP. Standardized motor fixation over generations, repairable units, flex battery options.
Would suggest you read about the difference between torque (Pinion top) and power (DJI top) - it completely explains your observation about the Pinion being great at slowly climbing up steep and technical hills vs the DJI being the king of climbing quickly. Pinion system is tuned for high torque and DJI for power. Torque is what you feel in the seat of your pants in acceleration, power gives a high speed!
Thank you. This was a great comparison. As a rider who only ever uses the lowest eco-power mode on my old 2017 Turbo Levo, I'm not looking for the fastest uphill in Turbo Boost. I'm leaning towards the Pinion MGU. I'd like to see you review the downhill and technical trail riding of a range of different bikes powered by the Pinon MGU / Gates Belt-drive system.
I have never ridden a bike with belt, but having both light motor and heavy duty ebikes, I would have gone with the belt on the high torque ebike. When torque is high, the chain system is crunching and I have to constantly dial down the power to shift. Maybe SRAM's new RD that shift better under load is a better choice? But belt bring a peace of mind in general I reckon.
If DJI offers a spare motor parts type website, with exploded diagrams for ordering and servicing the motor. They will be crowned king. For now. Don't forget, ZF hasn't had their chance yet, and unlike DJI, ZF will be available in North America. Interesting. Obviously, the DJI takes the win here. But personally, if price and possible serviceability were matched, I'd take the Saturn home. Some benefits are obvious. The not so obvious, I'd bet it's a better tech climber. Also, it's likely better on the downhill. Lastly, back country or just general big mile traversing, Saturn. Not to mention, the Saturn is unapologetic, industrial, and just awesome to look at.
As nice as the DJE is, I’ll sti😊ll take the Pinion hands down. No maintenance, shift while stopped, auto shift, etc. Now it’s time for the competition to come out with their own versions.
Having the gears midships seams such an obvious game changer. As an ebike rider with hub gears that take years of maintenance-free abuse, I've always scratched my head at the prevalence of chain/derailer setups. Where's the advantage?
@@Slimboid For road cycling, with a clean drivetrain, there are a couple of watts of efficiency gain. I think for other disciplines you are probably right. Maybe the simple construction can be seen as a benefit when something breaks. But the risk of it breaking is, as I guess You indicate, like eight times higher.
The shifting gearbox is typical german thinking. While the chinese says don’t care let‘s go to 2000W and 200NM in single speed ;) Gearbox are complex, expensive and heavier.
@@MinskUK Yeah. I've got the same issue. Not sure I can wait 5-10 years! I love the MGU+belt concept too, but that whine sounds pretty annoying too. Guess I'll have to try it.
I’ve been running the p18 as an early adopter, on an etrike, lots of dirt as it is full suspension and I have lived for a decade near Farragut park. It has always worked so flawlessly. Wow.
DJI is simply using the limits of their system (motor + controller + battery). Put more Phaseamps in, get more torque till the magnetic saturation limit of our electrical sheets in the motor is reached, or temperature derating starts. But this way they also need more Wh/km, if you are faster uphill... The energy still needs to come from somewhere. (physics!) I think it's cool, but for me riding an 2016 Specialized Levo with only setting 70% of e-support on max. levels, it's still just a great eMTB ride feeling. I tested the new Pinion ride, awesome belt drive and for me really too much power what I personally don't need on am eMTB. And now the DJI system even opens more power... if you really need this amount of power, consider removing the pedals and buy an electric motorbike. ;)
Not sure how I feel about more power than 80-90NM. Should eMTBs be closer to a mountain bike or closer to an emoto? 🤔 trail access is already a hard subject for eMTBs. If eMTBs become too powerful we could all loose access to some areas.
Exactly. Also, even with my old gen 2 Bosch, I don't like the "turbo" mode because so much assistance spoils the natural feeling of pedaling. It's only good if I am commuting to work and want zero sweat.
I think You ask the right question. With coming to par with electrical trail motorbikes where will eMTBs be regulated? In Europe, +250W requires a license. But it's hard for an officer telling models apart. Will it be regulated by mandatory wireless transponders as with air traffic? As with the scooters running circles around pedestrians in the cities I believe our nature experience will suffer if too many vehicles invade. If they also put out more energy than a human possibly can they will erode trails which in turn become less attractive for trekking humans, or animals for that matter. It's a great benefit they are silent though.
800 wh option in the dji will help as does the 4-5kg less the bike system weighs , also if you dont use full power it comes down to motor efficiency instead and i suspect its very good , all that said it would make a fantastic video for sure.
I was at Coed Y Brenin in Wales when The Don from GMBN was on the Amflow we both did the same trail which is around 20km and both used 40% battery, my bikes got the Bosch CX gen 4 with a 750 battery and my bike weighs around 27kg, I’m also a heavier rider than Neil, not sure which mode he used but I was in auto the whole way, pretty sure he did it a lot faster than me as well. I can just go and change a battery but he put the Amflow on charge using the fast charger and it was back to full in around 30/40 mins, enough time to have lunch!👍🏻
In a German review (ride better bikes) he did a range test on the amflow and came to the conclusion that he got similar far in the amflow than with a Shimano or Bosch, but also in turbo (850w), meaning that it is actually more efficient and if you ride trail, which is Shimano boost bosch turbo you'd get more range out of it
Game over!! I'm pretty sure DJi will be capable of making a reliable motor, like most brands I'm more interested in how it copes with the UK's weather, this is the real test. I've never had a problem with my current brose or Bosch in my rail and Shimano in my Merida, but I maintain after every ride. If I were in the market for a new ride the Amflow would be it.
I think it doesn't matter what is the power. Gearbox is the future especially for ebikes. Once the big manufacturers pickup on this, the tech will move forward fast and hopefully we will ditch mechs for good. Hate mechs on ebikes. Don't align it perfectly and the power of ebike will chew your whole drivetrain really fast.
Have been waiting for so long for such a powerful motor. Hope that Amflow come up with a longer travel version of the bike, which is what I would definitely buy. However, I heard Troydon from Crestline saying on a podcast, that the new Bosch motor will get a software update in the coming months, boosting torque to 100-105Nm, that would be interesting
Probably unintentional but this is massive advertising for DJI - and I do not mind at all! It looks like really, really good product. I very much expect the long term review.
DJI was impressive, no doubt. But I'm infatuated with the concept of an MGU and belt drive. Like many others, I feel that is the future of carefree riding. Especially for people who like to, or have to (commute), ride all year around including in cold, wet and snowy conditions. Needless the say, the MGU might need another two revisions or so, before reaching its full potential, but I'd take a Nicolai Saturn 16 anytime.
Maximum power: Comparing the power of motors in reviews also seems a bit strange to me. On longer trips, the battery does not allow for continuous riding in maximum support mode, so maximum power can be used occasionally, so it does not matter so much in the overall use. At the beginning of the eMTB adventure, playing with full engine power is very nice, but after longer use I personally try to use less support to have a good balance between fun and training. On full support (even limited to 25 km/h) the bike turns into an electric scooter, because the muscle input is marginal. However, I want a reasonable mix of engine work and my legs.
Great combination 12-13speed MTB with tiny front sprocket and super torquey mid mount motor, really maximizes the chain force and tooth pressure and minimizes longevity of the drivetrain
Motors are important, but number one thing for me is downhill performance. My levo has a cascade link to make it 160mm. The fork is a zeb ultimate with 170mm. My decoy has coil and 180mm up front. Would love to see not only how they go up, but how do they compare going down.
Brilliant video Rob! really one that we wanted to see. For me, the perfect e-bike would be: - DJI's wireless controllers, screen and battery - Bosch's silence and power (DJI's seems really overkill) - Pinion's gearbox and belt. I will NOT buy an e-bike with a derailleur and cassette ever Guess I'll have to wait a year or two still
I already rode the Nicolai at Bikepark Bischofsmais. (Ok not this one with alle the Intend) It just works sooo extremely nice on the downhills. It is long and stable on the rough stuff (typical Nicolai). But with enough speed it was so much fun on the flowcountry trail as well. aand I even had the huge 960wh battery! This low and central center of gravity and low unsprung mass on the rear is just the best on the downhills! I could not believe I was riding such a heavy bike - especally after the flowtrail jumps. On handling tight stuff on the uphills you feel the heavy bike, of course. Gearbox is okay - but I am used to the sound of the Rohloff hub on my bikepacking bike. It is just more reliable - and brings all the mass where you want it on the downhills.
Lately, everyone on YT is trying to sell the Amflow and its DJI motor but no one makes a test range. I really see people getting excited with DJI’s turbo mode, then they ride around the block twice and return home to recharge the battery :)))) I'll leave the reliability tests to the early adopters who are the ones who always pay the biggest bill. There is something that I am already beginning to foresee with some concern. Soon we will no longer be able to take our bikes to the trails we love so much because they will be considered electric motorcycles. And still no one has remembered to mention the dangers of fire during the summer when we ride electric bicycles through the woods. I'm about to buy an Orbea Rise or Wild, I haven't decided yet - maybe the Wild because of the Bosch engine - but unfortunately I'm starting to think that I'm going to do this at a time when the law will start chasing us. Lots of regulation, conditioned access to trails and expensive insurance to name but a few. Exactly the same as what happened with drones. I hope I'm wrong.
As for range... i did a 31km ride in mostly turbo mode on a full 600wh battery on my Amflow the other day (weigh 70kg) Not loads of elevation, but a few steep climbs in the 30 sec boost mode etc... Finished the ride at about 3% battery. Once you get to 5% battery the assistance really drops off... The most fun bike ride i've had in a very long time!
@@willgreenfield My bike rides are usually between 45 and 50 km. The ascende varies according to the mood of the day :) I always try to do more than 500m. Now that I want to buy an e-bike, I don't want to do less. Rather the opposite. So I have to choose wiselly. Thank you very much for your testimony.
@@PGNogueira no problem! I think you should definitely be able to do that length of ride with the bigger 800wh battery and using the eco/trail/auto modes
@@PGNogueira I'm 100kgs I ride a 120mm fully (with suspens lock) 14kgs muscular bike in 2024 I did 87km 1252km other than that I do the same as you for example 40-50km 0-500d+ I rented a bosch gen4 26kgs alu mullet 29-27.5 ebike and did 37.62km 1772d+ in 5h04 on which you can remove 15min of hiking because there was already snow at the summit and did the last bit on foot 750wh battery and I had 25% left ascent on road/gravel till 10% slope I did mostly on eco (above drained the battery too fast) 10-20% slope i did on tour 20% or more I used emtb but there weren't many of those (pedestrian hiking ascents not meant for bikes) I never used turbo don't see the point as I was falling backwards from the bike because of how steep some parts where and on emtb the tire already started slipping despite the massive motocross like 2.6t tires, except trying to do a backflip it would have been useless to have more power P.S. I was somewhat tired after that but nowhere near the strain and time it would have taken me without an engine, most of my fatigue came from the gigantic handlebar felt like riding a boat I cut all mine shorter
A lot of folks seem upset about the power. Seem to think riders will be flying along like dirt bikes. But Amflow has the same limits as any other ebike, can be run on lower settings to increase range, and has that incredible power on tap if needed. Hard to see a real issue. Unless you just went and dropped $20k AUD on a boutique brand that is now looking a bit off the pace?😉😁 Would love to see DJI work on a gearbox now. Then I'd be looking at entering the ebike market👍👍
What is the difference in Cadence rpm the motors support? Is there field weakening taking place to support higher rpm? Could be that some motors deliver more power when panddeling slower in a higher gear.
Why do we even need a gearbox? I mean if a Tesla has no gearbox why do we need it on a bike? Is there a system where I just pedal and the motor adjusts the power along with what is needed? Sorry for perhaps a silly question.
I would like to see the DJI timed up the hill without the 30 second boost enabled. That would have been a more fair comparison since most climbs are way more than 30 seconds.
@@RobRidesEMTB, this test is misleading as my climbs are at least 30 minutes and sometimes several hours when climbing bigger mountains. I can't press the boost button every 30 seconds as that detracts from the biking experience and even more so if I'm in the middle of a technical section when I would need the assistance the most. I would appreciate a more realistic comparison.
@@dansadventures5514I live in the mountains. Verry steep mountains and also difficult slopes. You don‘t have always to push the boost mode button. The Boost Mode brings only 15 Nm more Power. Standard power from DJI avinox is 105 Nm, that is definitly enough for big mountains. So this test is pratical an realistic.
@@makro8218if the boost mode isn't needed or expected to be used then the comparison should be done in a way that represents the real world otherwise it's misleading
@@dansadventures5514come on…. The boost push it up only 15 Nm. That is a little bit more power, but not the double ore something else. If is your question why was used the boost mode I ask why the other companies doesn‘t have it also? Thats not the trouble from DJI when other are „to stupid“ for it. And another thing, now I have a specialized, I didn‘t use all the time on every ride the full power…. Power is good to have, but it is unrealistic to use it always.
Kudos to DJI for setting up the bar here for others to follow on their next gens. Just thinking with all that power comes with great wearability and tearability so lets see more consumer reviews in the next year and see how it goes.
As always another great quality video Rob cheers,DJI motor package deffo on a nother level do you know anything about serviceability and after sale service for the UK and what happens when the warranty runs out will replacement motors be available wish they would be more transparent about all the things a lot of us would love to know before investing,do you have any insight cheers Rob.Always look forward to seeing new content keep them coming, thanks for all your hard work 😊💯
I noticed on the bosch that pedalling backwards actually reversed the drive train 👌 that's got to be a first ? 🤔 It's definitely true how quickly the dji will eat, not just chains but also the complete drive train. A huge and expensive problem
As a DJI commercial drone pilot, DJI is dominating the global market with their technology, if this bike is going to be as advanced and dependable as their drones, it's already a win-win with that much smaller lighter motor that is more powerful and a bigger battery. DJI is taking over the world!!! Nothing competes with them.
Nice video only thing that the Dji have much more watt than the other 2 so hard to compare. I'm driving a Cube with a Bosch cw gen 4 for several years now and mostly the eco drive. Due to legal reasons just 250 watt but it never let me down.
I never had the feeling that a Bosch or Pinion motor didn't have enough power. As a rule, I ride with 75 - 80% support, for example in E-MTB mode and not in turbo. So what do you actually need this power for, which, as the test shows, is impossible to get on the ground. And probably also stresses the entire drive train. Maybe for a cargo bike🤔
Nominal power (regulated to 250w) ≠ peak power. Nominal power is the power your motor can deliver anytime and permanently without risk of damaging the motor. Peak power on the other hand is the power your motor can do when it's needed, for example accelerating or rising uphill, but this cannot be done permanently (limited by overheating and shutting down power after a time). Just like a human who can ride flat at 20kmh no wind no problem, but accelerating or going uphill makes us sweat and we can't do that permanently. Tldr: nominal power is limited to 250w (regulated by the government), the motor has to be designed to basically overheat when putting out more power. Peak power on the other hand is not regulated and can be how much the manufacturer wants, he decides the absolute limit of the mechanical and electronic parts to be reliable without breaking or catching fire. That's why Shimano can just put out a software update for the ep801 to deliver more power, because the peak power is theoretically unlimited, but limited by software and sensors from the manufacturer. practically for shorter durations, if you try to draw 2000 watts out of a Bosch CX the wires will start to burn after 3 seconds since they are not thick enough for the massive amounts of amps going through there (or battery) or the gear teeth will just break
DJI has been in the high tech motor for long time with their consumer and commercial drones. I am fairly confident they are going be very reliable in the long run.
Perfectly optimized test setup for DJI's 30s boost mode.
From what I've seen online that 30s isent actually 30s and you can keep pushing it again and again and it will keep giving you boost.
you can nearly push it unlimited
@@derzerstoerer1 Does battery know that?

just change bike evry 2 year, you absically spend less in keeping everything in place XD
at least for me that i do more "downhill" style ride, rather than trail/cx/enduro
jopkes aside, u def have a good point
They haven't invented time travel yet but if you figure it out please let us know how those test results turned out.
You should buy bosch gen2, its for you!
The Pinion with DJI power in an affordable 180mm travel alu frame and its christmas :)
Stunning bike that DJI , looks the part as well
Cant' wait to see a good bike brand with DJI. I will buy it for sure!
Me, too. Druid or Dreadnought?
Hello Rob.
I've owned a high torque/performance bike before (Flyon 5.0). Verry heavy bike with lots of torque but still didn't get up all hills like with the PWX3 motor I own now. Too much torque weare out your equipment much faster, chains break... I've tested Pinion (Simplon bike) @ Garda and must say I was very pleased with its outcome. In '26 I definitely will get a Nicolay with Pinion...🎉
Good vids you bring out ❤.
Rolando.
The concept of the Pinion MGU is the future. Combining the gearbox and motor into one unit has so many advantages. This is the first version, I'm sure it'll only improve over time.
They are not the first to do that
Looking at the price. And current Shimano linkglide drivetrains It’s not. It’s just way too complicated and expensive.
Except this concept has been around forever (even by them) and it is JUST now becoming somewhat viable and has a LONG ways to go... and that was before the DJI came out. Any hopes they had of matching the DJI power and range with their current designs are out of the question now. They basically need to nearly start over. Going to be a tough for them, imo.
No it’s just the only good way to shift with a belt drive.
Pinion works on gearbox from over ten years... and before of that they they were into the automotive sector (Porsche) so... they perfectly know what they're doing.
How much power is enough power? I think we’re reaching the limit of what anyone needs. Personally I’d value robustness and reliability of a motor system waaaaaaaay ahead of power. Time will tell with the newcomers!!
I want uncontrollable wheelies!
Been thinking about this a lot recently, with all of the Amflow vids plastered over YT. Don't get me wrong it looks great fun, but I own an ebike to get further afield (and maybe tackle some fun techy sections), not bast on turbo non-stop. I rarely ever hit turbo, because its not the same sport imo. Innovation is great, but lets see it impact the prices pls.
Bro, you forgot about traditional transmission guys) who need some help from e-friends to be towed uphill))
Dji drones are incredibly reliable and have very high build quality. I would not worry about their build quality…. I would worry about their support system which would probably be not great.
@@mlee6136the demand on an MTB is far greater than the demand from a light weight drone. DJI durability is completely unknown as it relates to e-bikes.
i was waiting for this❤️
Good review of those different units. I like the power and instant engagement of the DJI unit. I like the established reputation of the Bosch unit, it is also very quiet!. I also like the different integrated gearbox idea of the Pinion unit.
Loved the video and how you covered it. Can't wait to see the next ones. Not too sure about the background music.
Rob, I think I’ve commented this like at least 20 times on your videos, but your channel is so good! Really appreciate the hard work you put into these
Gearbox is the future!
Waiting for bosch creates their own gearbox
Maybe for botique brands but not for main stream big brands
They have it paired with Rohloff Speedhub and Gates Carbon Drive
They realy are not, way to inefficient, you realy do feel the drag on it, take one for a rip and you will notice it right away...
@@polska905 I use rohloff, sturmey archer, Alfine since 2005.
Far better solution than any cassete based solution. For ebikes the benefits are bigger
Future for ebikes is gearbox.
Hub motors were mainstream and after some good mid drives motors, this is the new top level standards. Gearbox will be the same.
ZF soon will show their own mgu too.
@@polska905it's a trade off. Personally the slight extra drag on my alfine 11 is easily compensated for by it's reliability and absolute silence of the belt drive.
dji will be "illegal "in many countries, because there is a 600 W limit, if stronger engine is used, a special permit is required
Yes, and comparing a motor with double the power is quite weird. In the car world this would be like comparing a rally car that can not drive on roads legally, and need repairs after races because it eats parts, to a every day use road car. I would buy the bosch as i hate noise because i am old and cranky. He did a good job explaining the change they made tho. I am going to save money for it and buy one next year when this new model becomes last years model on sale:)
Any of these models are amazing!!
As an engineer and former cycle mechanic I have to say that the smaller these units get the more wear the gears will have to endure, add that to the fact that only the Pinion has a wet sump for lubrication means that the new powerful motor/drive gear units will not last - especially if they are 1000W! I'll take longevity and reliability over ultimate performance, I mean a modern skinny chain ring/cassette/chain wears fast enough without that much power trying to destroy them 🙄. Also the quiet factor of bombing a rough downhill on a silent belt drive vs some gearbox noise uphill is worth it in my books.
As a none engineer, we all know technology improves, materials improve. An F1 gearbox handles 1000 bhp. Materials 20 years ago may have reliable issues but not today.
Agree, belt drive is the way for powerful mid drive ebikes. These chains and cassettes are not made for so much torque.
they arent worried as they expect you to replace the bike within 5years 😉
@@kl9518 sure there is some progress in materials but not as much as people think or hope. However your formula 1 example is a bit strange as the cars in 1988 F1 had about 1500bhp and the current ones only have 1000bhp. So when materials where already good enough for 1.5 times more abuse then they get now that proves nothing at all. The reason for reduction in power in F1 is due to stricter rules. As F1 became too dangerous and had more incidents that did not end well in those days.
@@chinesepopsongs00 Ermm, material science has actually come much much further than you would imagine with far more exotic materials available for consumer goods than ever. And gearboxes in F1 cars now are more compact and engineered to much higher precision than those in the 80s ever could be, and could easily be engineered to handle 1500 bhp if they were required to.
The DJI looks great. It’s a fantastic motor. Objectively more powerful. Unfortunately there’s not many service centres in my country. Only a couple stores are authorised centres. There’s not many in the US even. I love to see the competition, but until you can walk into any bike shop and buy the DJI and have it serviced there, it’s merely a very cool novelty. That’s the massive issue that nobody is talking about. Regardless though, I really love to see this competition. It’s fantastic.
I ride a Trek Rail with an 85nm Bosch, and a Haibike XDuro Yamaha before. I just wanted a little help, not a lot, up the hill now that I'm older & fatter with problem knees but that DJI 120nm is very tempting.
Incredible performance from DJI but as you said Rob it’s part of the story still lot of unanswered questions such as reliability, water ingress etc plus how the bike rides some people won’t want all that power and I still think people will plump for the Bosch due to the options of bikes out there using the motor but credit where credit is due DJI have knocked it out of the park with the whole package, just make sure you have a back stock of chains and cassettes as you will burn through them in no time 😂 great review though Rob 👏
that is for sure, it will eat up chains and cassettes much faster than any other bike
The DJI and Pinion MGU setup together would be the go for power and durability. Chains and cassettes are expensive and will surely offset the extra cost of a gearbox over time.
Dji has a great reputation for quality and reliability for their drones. I'm sure it will be the same this bike.
China makes some of the best products in the world today.
The video everyone has been waiting for 😮❤
looking forward for the standalone review of the amflow
Very nice test, but what I'm really interested in is how the downhill performance of the DJI compares to the Orbea? A powerful motor isn't everything if the rest isn't right. A comparison would be really cool.
Great balanced review Rob! DJI definetely takes the win here, with the power it provides the rattling noise seems like a minor issue..plus a really good build! would love to get my hands on it one day!
Far from balanced, take a step back and you’ll notice the test was perfectly setup for the DJI to shine, do you think it was coincidence that the test was 30 seconds when the boost on the dji was also 30 seconds.
Have you had the chance to ride the ZF system? I waited, and am super interested in the DJI system when I saw it announced earlier this year. great job again.
My dentist is going to love this
The dji has a 2 year warranty, like any other quality brand out there.
They have selected only a few quality retailers to supply and support their product. This is already a hugely significant manufacturer of quality and reliable products, used throughout this format and many others.
Obviously they have done their due diligence with research, development and marketing, with regarding their project.
They have built a bike from scratch to showcase their abilities. This alone is incredible. A new bike and motor that simply blows everything existing away.
I'm sure they will support this and grow what they have done.
A trail bike again makes far more commercial sense than a full fat Enduro. More people ride trail bikes than anything else in this sector.
I've ordered one and can't wait. I have no concerns over both reliability or support 👍😊
They don't take orders yet from the site
@@fofopads4450 not sure about ordering from the Amflow site? I've ordered mine and paid the deposit from a local approved stockist, with allocation due between Oct and Dec 👍
@@fofopads4450 Depends on where you live, I think.
Yamaha has 5 years
This is like a Carwow video for E-bikes 😂
11:59 Regarding the “fully integrated battery” on the Bosch. This isn’t a “Bosch thing”. It’s specific to that bike model. Most Bosch bikes have a removable Powertube. The manufacturer can use either one. It’s up to you to choose a bike with the battery that you need.
I remember when mountain biking was about mountain biking now it’s all about “my motors better than yours “ 😂
Best comment here😁
Every day I hate electric bikes more and more. Unless people are sick or some kind of age
Because before ebikes never an MTB owner had been seen saying "my is better than yours"
@@fundidoarrojo269 no they proved it by working hard with their muscles achieving something
I remember when it took skill to ride around on a penny farthing. Then along came these contraptions with pedals/brakes/gears/shocks and no one needed any strength or skill...😂
Great video, great content, great style, thank you rob!
I’d really like to see the time in the top (non 30s boost) mode to see the comparison over a 5+ minute climb in a mode you can actually stay in.
I like the orbea look 🔥🔥🔥
I really hope the other brands now start thinking of developing their USP. Standardized motor fixation over generations, repairable units, flex battery options.
That’s Yamaha
ZF announced a really neat new ebike motor. It uses strain wave gearing to make it VERY compact.
Would suggest you read about the difference between torque (Pinion top) and power (DJI top) - it completely explains your observation about the Pinion being great at slowly climbing up steep and technical hills vs the DJI being the king of climbing quickly. Pinion system is tuned for high torque and DJI for power. Torque is what you feel in the seat of your pants in acceleration, power gives a high speed!
Rob, excellent review as always, appreciate the honesty and can't wait for more!
Thank you. This was a great comparison. As a rider who only ever uses the lowest eco-power mode on my old 2017 Turbo Levo, I'm not looking for the fastest uphill in Turbo Boost. I'm leaning towards the Pinion MGU. I'd like to see you review the downhill and technical trail riding of a range of different bikes powered by the Pinon MGU / Gates Belt-drive system.
I wish some one would run this same test against the Luna cycle x2 with ludicrous
This is a good ad for the DJI motor.. hope they payed well for this
Climb time from dji without boost mode?
Makes little sense of course super-eco us slowest
Nice to see something new. Maybe it gets Bosch to speed up their improvement cycle.
Just for ease of maintenance I’m saving up for a belt drive system. I hate derailers and chains.
I have never ridden a bike with belt, but having both light motor and heavy duty ebikes, I would have gone with the belt on the high torque ebike. When torque is high, the chain system is crunching and I have to constantly dial down the power to shift. Maybe SRAM's new RD that shift better under load is a better choice? But belt bring a peace of mind in general I reckon.
Thanks fr the review!
If DJI offers a spare motor parts type website, with exploded diagrams for ordering and servicing the motor. They will be crowned king. For now. Don't forget, ZF hasn't had their chance yet, and unlike DJI, ZF will be available in North America. Interesting.
Obviously, the DJI takes the win here. But personally, if price and possible serviceability were matched, I'd take the Saturn home. Some benefits are obvious. The not so obvious, I'd bet it's a better tech climber. Also, it's likely better on the downhill. Lastly, back country or just general big mile traversing, Saturn. Not to mention, the Saturn is unapologetic, industrial, and just awesome to look at.
As nice as the DJE is, I’ll sti😊ll take the Pinion hands down. No maintenance, shift while stopped, auto shift, etc. Now it’s time for the competition to come out with their own versions.
I never saw any prices but I guess the Pinion is far more expensive?
Having the gears midships seams such an obvious game changer. As an ebike rider with hub gears that take years of maintenance-free abuse, I've always scratched my head at the prevalence of chain/derailer setups. Where's the advantage?
@@Slimboid For road cycling, with a clean drivetrain, there are a couple of watts of efficiency gain. I think for other disciplines you are probably right. Maybe the simple construction can be seen as a benefit when something breaks. But the risk of it breaking is, as I guess You indicate, like eight times higher.
@@Slimboidprice
The shifting gearbox is typical german thinking. While the chinese says don’t care let‘s go to 2000W and 200NM in single speed ;)
Gearbox are complex, expensive and heavier.
I'm most excited about the Pinion MGU, but not this one, the one 5-10 years from now when they get it fully ironed out.
Doh! I’ll be 66 or 71, I’m not sure my knees can wait 😂
@@MinskUK Yeah. I've got the same issue. Not sure I can wait 5-10 years! I love the MGU+belt concept too, but that whine sounds pretty annoying too. Guess I'll have to try it.
I think they've made a mistake in using spur gears instead of helical ones. They are a bit more expensive, but way more silent.
I’ve been running the p18 as an early adopter, on an etrike, lots of dirt as it is full suspension and I have lived for a decade near Farragut park. It has always worked so flawlessly. Wow.
I would love to replace my system with this and ditch the weight of my hub motor
I use my bike for commuting and transport. Holding 25kph+ uphill is important for me. Reliability and range is also important.
The Sprague clutch in the Dji is really nice!
DJI is simply using the limits of their system (motor + controller + battery).
Put more Phaseamps in, get more torque till the magnetic saturation limit of our electrical sheets in the motor is reached, or temperature derating starts.
But this way they also need more Wh/km, if you are faster uphill... The energy still needs to come from somewhere. (physics!)
I think it's cool, but for me riding an 2016 Specialized Levo with only setting 70% of e-support on max. levels, it's still just a great eMTB ride feeling.
I tested the new Pinion ride, awesome belt drive and for me really too much power what I personally don't need on am eMTB.
And now the DJI system even opens more power... if you really need this amount of power, consider removing the pedals and buy an electric motorbike. ;)
Not sure how I feel about more power than 80-90NM. Should eMTBs be closer to a mountain bike or closer to an emoto? 🤔 trail access is already a hard subject for eMTBs. If eMTBs become too powerful we could all loose access to some areas.
Exactly. Also, even with my old gen 2 Bosch, I don't like the "turbo" mode because so much assistance spoils the natural feeling of pedaling. It's only good if I am commuting to work and want zero sweat.
I think You ask the right question. With coming to par with electrical trail motorbikes where will eMTBs be regulated? In Europe, +250W requires a license. But it's hard for an officer telling models apart. Will it be regulated by mandatory wireless transponders as with air traffic? As with the scooters running circles around pedestrians in the cities I believe our nature experience will suffer if too many vehicles invade. If they also put out more energy than a human possibly can they will erode trails which in turn become less attractive for trekking humans, or animals for that matter. It's a great benefit they are silent though.
Stand up for yourselves, don't simply accept trail closures.
A range test comparison would be interesting - how many metres of vertical in boost - I imagine the DJI will run out of juice fairly quickly
800 wh option in the dji will help as does the 4-5kg less the bike system weighs , also if you dont use full power it comes down to motor efficiency instead and i suspect its very good , all that said it would make a fantastic video for sure.
I was at Coed Y Brenin in Wales when The Don from GMBN was on the Amflow we both did the same trail which is around 20km and both used 40% battery, my bikes got the Bosch CX gen 4 with a 750 battery and my bike weighs around 27kg, I’m also a heavier rider than Neil, not sure which mode he used but I was in auto the whole way, pretty sure he did it a lot faster than me as well. I can just go and change a battery but he put the Amflow on charge using the fast charger and it was back to full in around 30/40 mins, enough time to have lunch!👍🏻
In a German review (ride better bikes) he did a range test on the amflow and came to the conclusion that he got similar far in the amflow than with a Shimano or Bosch, but also in turbo (850w), meaning that it is actually more efficient and if you ride trail, which is Shimano boost bosch turbo you'd get more range out of it
@@eaze7324 Yes the data I have seen so far suggests the DJI wins on every level. It's a big wake up call for every manufacturer out there
Game over!! I'm pretty sure DJi will be capable of making a reliable motor, like most brands I'm more interested in how it copes with the UK's weather, this is the real test. I've never had a problem with my current brose or Bosch in my rail and Shimano in my Merida, but I maintain after every ride. If I were in the market for a new ride the Amflow would be it.
I think it doesn't matter what is the power. Gearbox is the future especially for ebikes. Once the big manufacturers pickup on this, the tech will move forward fast and hopefully we will ditch mechs for good. Hate mechs on ebikes. Don't align it perfectly and the power of ebike will chew your whole drivetrain really fast.
At what point is that just a motorbike?
@@jimporter when you don't have to pedal imho
Great reviews. Thanks for the details.
Have been waiting for so long for such a powerful motor. Hope that Amflow come up with a longer travel version of the bike, which is what I would definitely buy. However, I heard Troydon from Crestline saying on a podcast, that the new Bosch motor will get a software update in the coming months, boosting torque to 100-105Nm, that would be interesting
will certainly watch the Amflow prices and the reliability comments in the future .
Getting tiered of the lack in Cx 4 Waterproofing .
Did you have issues with the Bosch CX g4 being not waterproof?
Probably unintentional but this is massive advertising for DJI - and I do not mind at all! It looks like really, really good product. I very much expect the long term review.
But no one talk about the avinox frame….stiff….flex….
DJI was impressive, no doubt. But I'm infatuated with the concept of an MGU and belt drive. Like many others, I feel that is the future of carefree riding. Especially for people who like to, or have to (commute), ride all year around including in cold, wet and snowy conditions.
Needless the say, the MGU might need another two revisions or so, before reaching its full potential, but I'd take a Nicolai Saturn 16 anytime.
The DJI bike is going to shake up the eMTB market for sure
Maximum power: Comparing the power of motors in reviews also seems a bit strange to me. On longer trips, the battery does not allow for continuous riding in maximum support mode, so maximum power can be used occasionally, so it does not matter so much in the overall use. At the beginning of the eMTB adventure, playing with full engine power is very nice, but after longer use I personally try to use less support to have a good balance between fun and training. On full support (even limited to 25 km/h) the bike turns into an electric scooter, because the muscle input is marginal. However, I want a reasonable mix of engine work and my legs.
No removable battery is just no go for me... I ride on gen4 Bosch in this moment, and it is absolutely no reason to change.
Great combination 12-13speed MTB with tiny front sprocket and super torquey mid mount motor, really maximizes the chain force and tooth pressure and minimizes longevity of the drivetrain
Motors are important, but number one thing for me is downhill performance. My levo has a cascade link to make it 160mm. The fork is a zeb ultimate with 170mm. My decoy has coil and 180mm up front. Would love to see not only how they go up, but how do they compare going down.
Brilliant video Rob! really one that we wanted to see.
For me, the perfect e-bike would be:
- DJI's wireless controllers, screen and battery
- Bosch's silence and power (DJI's seems really overkill)
- Pinion's gearbox and belt. I will NOT buy an e-bike with a derailleur and cassette ever
Guess I'll have to wait a year or two still
Rob, love that you are including the weight / kWh metrics. Great video!
Pinion for me. No question. Just bring it already
Would love an ultra steep section test with all bikes in gear one...
The setup on the Nicolai is pretty unique, WT, intend, certainly not generic.
The Orbea looks so nice
Very interesting Video thanks !
Great review. Thx
Would be also fun to watch analog bike time to climb comparison with those ebikes
This was awesome! Would be interesting so see the time for the Amflow in high setting, not the 30-second boost of demon mode it has.
I already rode the Nicolai at Bikepark Bischofsmais. (Ok not this one with alle the Intend) It just works sooo extremely nice on the downhills. It is long and stable on the rough stuff (typical Nicolai). But with enough speed it was so much fun on the flowcountry trail as well. aand I even had the huge 960wh battery!
This low and central center of gravity and low unsprung mass on the rear is just the best on the downhills!
I could not believe I was riding such a heavy bike - especally after the flowtrail jumps.
On handling tight stuff on the uphills you feel the heavy bike, of course.
Gearbox is okay - but I am used to the sound of the Rohloff hub on my bikepacking bike.
It is just more reliable - and brings all the mass where you want it on the downhills.
Lately, everyone on YT is trying to sell the Amflow and its DJI motor but no one makes a test range.
I really see people getting excited with DJI’s turbo mode, then they ride around the block twice and return home to recharge the battery :)))) I'll leave the reliability tests to the early adopters who are the ones who always pay the biggest bill. There is something that I am already beginning to foresee with some concern. Soon we will no longer be able to take our bikes to the trails we love so much because they will be considered electric motorcycles. And still no one has remembered to mention the dangers of fire during the summer when we ride electric bicycles through the woods. I'm about to buy an Orbea Rise or Wild, I haven't decided yet - maybe the Wild because of the Bosch engine - but unfortunately I'm starting to think that I'm going to do this at a time when the law will start chasing us. Lots of regulation, conditioned access to trails and expensive insurance to name but a few. Exactly the same as what happened with drones. I hope I'm wrong.
As for range... i did a 31km ride in mostly turbo mode on a full 600wh battery on my Amflow the other day (weigh 70kg) Not loads of elevation, but a few steep climbs in the 30 sec boost mode etc... Finished the ride at about 3% battery. Once you get to 5% battery the assistance really drops off... The most fun bike ride i've had in a very long time!
@@willgreenfield My bike rides are usually between 45 and 50 km. The ascende varies according to the mood of the day :) I always try to do more than 500m. Now that I want to buy an e-bike, I don't want to do less. Rather the opposite. So I have to choose wiselly. Thank you very much for your testimony.
@@PGNogueira no problem! I think you should definitely be able to do that length of ride with the bigger 800wh battery and using the eco/trail/auto modes
@@willgreenfield Thank you once again.
@@PGNogueira I'm 100kgs I ride a 120mm fully (with suspens lock) 14kgs muscular bike in 2024 I did 87km 1252km other than that I do the same as you for example 40-50km 0-500d+ I rented a bosch gen4 26kgs alu mullet 29-27.5 ebike and did 37.62km 1772d+ in 5h04 on which you can remove 15min of hiking because there was already snow at the summit and did the last bit on foot 750wh battery and I had 25% left ascent on road/gravel till 10% slope I did mostly on eco (above drained the battery too fast) 10-20% slope i did on tour 20% or more I used emtb but there weren't many of those (pedestrian hiking ascents not meant for bikes) I never used turbo don't see the point as I was falling backwards from the bike because of how steep some parts where and on emtb the tire already started slipping despite the massive motocross like 2.6t tires, except trying to do a backflip it would have been useless to have more power P.S. I was somewhat tired after that but nowhere near the strain and time it would have taken me without an engine, most of my fatigue came from the gigantic handlebar felt like riding a boat I cut all mine shorter
A lot of folks seem upset about the power. Seem to think riders will be flying along like dirt bikes. But Amflow has the same limits as any other ebike, can be run on lower settings to increase range, and has that incredible power on tap if needed. Hard to see a real issue. Unless you just went and dropped $20k AUD on a boutique brand that is now looking a bit off the pace?😉😁 Would love to see DJI work on a gearbox now. Then I'd be looking at entering the ebike market👍👍
I love your Vids Rob and this one is very helpful. Almost 1 Million subs!!!! Finger crossed you hit it soon!
Only thing holding back the DJI is the fact that it’s on a trail bike. I’d love to see hard enduro spec
Me too!
@@sety409 It won't be long till another manufacturer has the DJI in a long travel Enduro chassis
What is the difference in Cadence rpm the motors support? Is there field weakening taking place to support higher rpm? Could be that some motors deliver more power when panddeling slower in a higher gear.
Why do we even need a gearbox? I mean if a Tesla has no gearbox why do we need it on a bike? Is there a system where I just pedal and the motor adjusts the power along with what is needed? Sorry for perhaps a silly question.
I would like to see the DJI timed up the hill without the 30 second boost enabled. That would have been a more fair comparison since most climbs are way more than 30 seconds.
You can just press it again for another 30 seconds. I haven’t managed to get it to not work despite several continuous activations
@@RobRidesEMTB, this test is misleading as my climbs are at least 30 minutes and sometimes several hours when climbing bigger mountains. I can't press the boost button every 30 seconds as that detracts from the biking experience and even more so if I'm in the middle of a technical section when I would need the assistance the most. I would appreciate a more realistic comparison.
@@dansadventures5514I live in the mountains. Verry steep mountains and also difficult slopes.
You don‘t have always to push the boost mode button. The Boost Mode brings only 15 Nm more Power. Standard power from DJI avinox is 105 Nm, that is definitly enough for big mountains. So this test is pratical an realistic.
@@makro8218if the boost mode isn't needed or expected to be used then the comparison should be done in a way that represents the real world otherwise it's misleading
@@dansadventures5514come on….
The boost push it up only 15 Nm. That is a little bit more power, but not the double ore something else.
If is your question why was used the boost mode I ask why the other companies doesn‘t have it also? Thats not the trouble from DJI when other are „to stupid“ for it.
And another thing, now I have a specialized, I didn‘t use all the time on every ride the full power….
Power is good to have, but it is unrealistic to use it always.
Kudos to DJI for setting up the bar here for others to follow on their next gens. Just thinking with all that power comes with great wearability and tearability so lets see more consumer reviews in the next year and see how it goes.
As always another great quality video Rob cheers,DJI
motor package deffo on a nother level do you know anything about serviceability and after sale service for the UK and what happens when the warranty runs out will replacement motors be available wish they would be more transparent about all the things a lot of us would love to know before investing,do you have any insight cheers Rob.Always look forward to seeing new content keep them coming, thanks for all your hard work 😊💯
The review everyone was looking for!
I noticed on the bosch that pedalling backwards actually reversed the drive train 👌 that's got to be a first ?
🤔 It's definitely true how quickly the dji will eat, not just chains but also the complete drive train. A huge and expensive problem
As a DJI commercial drone pilot, DJI is dominating the global market with their technology, if this bike is going to be as advanced and dependable as their drones, it's already a win-win with that much smaller lighter motor that is more powerful and a bigger battery. DJI is taking over the world!!!
Nothing competes with them.
If amflow comes out with some alloy versions count me in! Also a removal battery would awesome.
Would be great to do a descending race with these 3 bikes too
The Nicolai/pinion has some engagement free before pedalling, but you neglected to mention the rear engagement on the meched bikes.
Nice video only thing that the Dji have much more watt than the other 2 so hard to compare. I'm driving a Cube with a Bosch cw gen 4 for several years now and mostly the eco drive. Due to legal reasons just 250 watt but it never let me down.
Good video. When you do the noise tests again please give us a bit of your voice on the bike so we have a reference for how loud they are. Thanks.
good point!
Simply stunning, it will be pretty interesting see how this shows on real racing territory 💪🏽
I wear out tyres and components quick enough with 85nm.. dread to think what the DJI motor will eat through. 😂
dji is for dirty dan tires))
The news sram transmission was designed with e-bikes in mind. I actually prefer the previous gen sram with a standard bike
I never had the feeling that a Bosch or Pinion motor didn't have enough power. As a rule, I ride with 75 - 80% support, for example in E-MTB mode and not in turbo. So what do you actually need this power for, which, as the test shows, is impossible to get on the ground. And probably also stresses the entire drive train. Maybe for a cargo bike🤔
Was wanting to go all in on the pinion but that motor noise leads me to believe to wait til a Gen2 comes out.
Why not use some power pedals to subtract out rider watts to more accurately determine motor watts?
also a question why the uphill is just around 30 seconds, what is quite the same time as the boost mode in DJI
2 questions. Is DJI legal pulling so much power, way over 250w? 2nd question, can Bosch decouple completely when turned off?
Nominal power (regulated to 250w) ≠ peak power. Nominal power is the power your motor can deliver anytime and permanently without risk of damaging the motor. Peak power on the other hand is the power your motor can do when it's needed, for example accelerating or rising uphill, but this cannot be done permanently (limited by overheating and shutting down power after a time). Just like a human who can ride flat at 20kmh no wind no problem, but accelerating or going uphill makes us sweat and we can't do that permanently.
Tldr: nominal power is limited to 250w (regulated by the government), the motor has to be designed to basically overheat when putting out more power.
Peak power on the other hand is not regulated and can be how much the manufacturer wants, he decides the absolute limit of the mechanical and electronic parts to be reliable without breaking or catching fire.
That's why Shimano can just put out a software update for the ep801 to deliver more power, because the peak power is theoretically unlimited, but limited by software and sensors from the manufacturer. practically for shorter durations, if you try to draw 2000 watts out of a Bosch CX the wires will start to burn after 3 seconds since they are not thick enough for the massive amounts of amps going through there (or battery) or the gear teeth will just break
happy with my shimano ep8 power….but it’s an integrated pinion gearbox motor that i want….go the pinion
