Rob, i just got my new nox xc trail with the Sachs rs motor with 112 Nm at low cadence . i have a cube with a bosch cx and was convinced it was the king of climbers until ,,,,, . i took the sachs up the same steep hills i usually ride and was traveling twice as fast at half the cadence in the third assist level ( it has four ). The sachs is insanely powerful and very well built . it's heavy with metal gears and casing . built to last .

Trash free trails would entail nuking the SOBs that litter in the first place!! I am near 60 and can honestly say I have never littered in my entire life.

Great update - Leaves me with two key questions : 1: Is this improved motor available to buy? 2 : If this improved motor is available to buy, how do you distinguish from the older motor before purchase?
Most Bosch motors are on ready to buy ebikes they are not kits and to buy a bosch usually used with someone with a damsged cycle, Bafang motors are available to build your own eBike and cost a fraction of the price of a Bosch motor built eBike.
@@bradburdett4491 yes I was comparing how some Chinese brands rate their lights at huge lumen ratings (hence the "Chinese lumens") and maybe there's a Chinese Newton Meter as they may also be exaggerated
Nm are not power. All that matters in the end is mechanical power, measured in Watts. Nm at the wheel can be levered with gearing. it seems the M500 has a 15A controller @43V that is slightly less power than the bosch cx (36V 20A). I don't know how many amps the 48v bafang controller can pull, but most likely less than 15A, since the motor can only handle a certain amount of power before overheating.
Rob....appreciate all you do on your channel. Man, you had me there for a moment, then I realized you were missing some very important variables. 42t 10spd vs 52t 12spd rear cassette and probably even more unfair in the front. The reality is battery voltage on the bafang is a game-changer. My Ultra motor is great at 48v, but is a whole different beast at 52v. My personal 52v Juggernaut Ultra FS, even with the Manitou mastodon and DT swiss BR2250 upgrades is half the cost of the Trek Rail. Yes it's 18lbs heavier, but it also has 4.8" surley tires, 160nm of torque, floats on snow and sand, climbs up a tree, and never ceases to bring smiles to myself or anyone that tries it for 5 minutes. Keep the snobby bosch, I guess I'm just bike trash.😁🤣
You are 100% correct. To the people who have never driven it, Bafang is a beast. Get yourself a M560, or a M620 and you’re golden. I’m not a fan of companies limiting and restricting their products. So keep your snobby Bosch indeed!
Just a quick question: Are the gear ratios the same on both of the bikes? You probably thought of that in trying to compare the motors, but if they aren't, ie the bikes don't have the same ring size on the crank, or they don't have the same sprocket size on the casset, then the climb test is comparing apples with oranges.
I understand this is a straight torque test but it would be great to know how the motor efficiency stacks up. Those Watt Hours in our battaries are heavy and dictate how long our day out is, for me I want to know I'm getting the most out of it, not just getting max power at any point. I only want enough power and good/best efficiency. If the Bafang is using more juice and being less powerful thats bad, but if its almost keeping up and using significantly less juice then brilliant.
Thanks Rob - I appreciate the honesty. Personally I like home builds. I accept that probably the Bosch motor is the best in class, but then look at the cost!!. It also occurs to me that when the warranty runs out the Bafang can be repaired by the user, not so Bosch as they are sealed units I believe?. So how would you think the Bafang stacks up against Shimano, Yamaha & Brose I wonder
I didn't see that coming, I figured you were going to bump to the m600.( would love to see the bafang m600 compete against the Bosch gen/4 ). And of course another great video. Thank you
Nice one Rob... I have the m600 on my CHEEB and must admit yet to be disappointed... (Not in the UK BTW)... It keeps up with all the expensive bikes on the trails and that's enough for me..
@@carsandotherstuffguy5300 Check out "electric biker review" if you haven't already. I also read a bit about the motor on Luna cycles X1 which had lots of vids and information to help make my decision...ruclips.net/video/X2IPtda_LFo/видео.html
When I was younger I had a Suzuki RM125 two stroke. What a monster... it screamed. 6 spd, clutch. You were actually involved with the machine and felt like you were part of it. There has been something lost with these eBikes where you just sit on them and turn the grip. Don't get me wrong... I have my collection of MTBs and have ridden my share of eBikes but... I only wish others could experience the thrill of riding a real two stroke dirt bike as I'm sure many here haven't. The power and the way its put to the ground has to be felt. Subbed my friend... keep them coming! 🚲
The secret is upping the voltage to arround 50v & patiently searching the web for the punch code to get rid of the rev limit. You see all these mid motors That have 80 or 90nm + are actually a lot stronger than 250w. You see with these motors, torque outputs stay the same regardless of revs (I’m disregarding torque multiplication from gearing, much of which is cancelled out by having a wheel of 26” to 29” anyway), but to get that sort of torque, they’re really motors that will sustain 600 to 800 watts. Then they apply a revlimiter to make sure they won’t sustain more than about 300w - Keeping them close to or plausibly legal while getting the torque figures of a motor twice as powerful. Cheating the speed limiter by moving the speed detector from the wheel to the crank or using a tuning chip may increase speed, but not when you really want it, going up steep hills, which is what e-assistance is all about. So if you really want to get the best performance you have to get a punch code or a tuner chip that releases the motor from it's built in revlimiter. Also upping the voltage from arround 40v to 50v helps stopping it get to hot as less amps are needed for the same watts.
If you're just doing off road trails why not just buy a full suspension bike around a grand and put a bafang bbshd motor in with 52v battery as I did, hills just ain't no more! ..sure beats messing around screwing every drop of power from a 250w motor!
None of these are close to 250 W. They all put out over 800 W maximum. The Bosch, Brose, and my EU legal Bafang M600s consume over 1 kW at max. But they are somehow still nominal 250W. And Nominal, what ever that means, is the key to keep it legal.
As a Bafang M620 and Bosch Gen 4. owner I can point out a few facts: M600 is the lowest spec'd Bafang you should consider Watt-wise. 250W Bafang motors are better only if you're DIY'ing your entire build. Compared to the M500 Bosch Gen 4. is much quieter, draws less power and has a much more soft assistance whilst still having more real world power. These Bafang motors are a great choice but only if you want to go over 250W and are able to DIY and know how to service these motors. Many countries have already/are legalizing 1000W motors. M620 is a good choice on that respect.
I have eagle 12 speed on my DengFu with a Bafang M600. That climb he did is a breeze on my bike. I do way longer and steep climbs than the climb in the video. The M600 is the way to go for this frame. And having that giant pie plate cog on the eagle cassette is also the way to go for very steep climbs.
@@EL34XYZ not everyone wants to own essentially a moped with cranks. Also with high wattage eats the battery quite fast. Not to forget heavy duty chains. Foes it have good shifting protection? Here in europe the m500 might be good choice if u want reqular emtb.
it would be interesting to see a motor test between flyon, sachs and the bosch. that's 120 vs 110 vs 95Nm based not just on hill climbs but weight to see a timed trail run to gauge agility
Hi Rob You need to compare with the m600 motor hands down better than any other motor ,I recently built a bafang,brilliant bike apart from a few annoying rattles,is yours the same Cheers John,
@@gavskxf on private land he can fo what he wants. I'd love to see the m600 and the m620 tested by him for an honest opinion. And it's not just about power but also I'm interested in the finess of the delivery.
@@stevenleslie8557 I have a m620 in s Frey ex and it is great. I have a dd 1000w hub drive too which is faster on the flat but obviously doesnt compare off road and hills against the m620.
100,000 lumens for only $24.99 no really. Not sure, but is the NM output of the motor directly measurable, similarly to HP output of a gasoline engine? If it can not be directly measured in a repeatable test, then a company could claim an e-bike motor at 200 NM when it really only puts out 65 NM.
I think its something to do with the seat tube angle. Chinese carbon frames have a fairly slack seat tube angle. That is why whenever I borrow my friends ebike with exactly the same motor. I always move the seat forward to steepen the seat tube angle which helps smoothen up the climb.
i have never run out of power on a climb with the Brose. When it gets to vertical the front lifts up or the wheel spins out. the motor isnt the failure point.
Thanks for showing, if bike sales keep diminishing a vid on making older bikes more modern and better suspention,ect. Wouldnt be a bad idea. I'm putting a cascade link on levo and mulleting it. I drool over Gen 3, but you can't get one here, and they don't offer the model I want yet.
Back to the drawing board for Bafang. My biggest concern is longevity. Motor drives are no cheap and I wouldn’t fancy a rebuild or replacement every 2-3yrs. As for trash free trails, the answer is simple. All those using them respect them and take your litter home!
Where Bosh is a closed system,.so all parts need to be bosh/manufatcter approved to work.If on chip fails ..you need to buy specific expensive parts,lSpecial dealer only software to adjust settings. Bafang gives you more freedom.Special on bataries and displays,and custom settings.
I knew I noticed that hill climb from somewhere, you used a TQ motor on it from a previous video. Ended up buying a Haibike Flyon bike after seeing that video, now living on beans n toast for the next few years or so :)
See if you can get hold of the M600s motor (EU legal special version of the M600) It will beat or match the Bosch motor. I have almost the same setup with the same frame but the M600s motor. I've never seen a hill where I have any trouble getting up unless I loose grip og flip the bike over.
Hi Rob Would you like you to do a review with my Dengfu e10 with m600 motor against your trek and new spes s works ,have a trip up to peaks it’s on my doorstep cheers john
I wish you still had the CHEEB so that the hill climb could be retested. Based on your build video and photos on emtb, it looks like the Trek Rail 5 had a gearing advantage of anywhere from 9% to 13%... No wonder it beat out the CHEEB/Bafang.
Rob you need to try seat down and sitting and leaning forward. Then you load the weight on the rear wheel. Maybe the befang is to powerful and is judt spinning up
It's great to see someone finally do a legit hill comparison. It would be great to see the EP8 and Bafang Ultra with Archon X1 (Watt Wagons) controller. EP8 won't do much but that Archon is rated at 160 Nm. Hope the next CHEEB uses one of those!!!
So it seemed to me that the Bafang bike could not climb something that a regular bike could do in short gear. I climb stuff like that all the time, just at the limit of traction and balance. Did I miss something?
Personally I'm more interested into comparing BBSHD versus Archon engine. Both seem to produce 160nm from engine. Gear ratio must be usable for climbing and high speed on road.
What was the weight of both bikes? and what was the gearing? Also what batteries were in them and were they both charged to full? were they the same? & what are the costs of each ??
Ah, even though the advertised Nm torque figure of the Bafang is higher, the sheer finesse of torque delivery of the Bosch is just top-notch. Good comparison! I have to ask if you'll entertain the idea of testing those built Bafang motors with an aftermarket controller? Innotrace is one of them
So basically: Ya-get-what-ya-can-pay. And going uphill depends on a few factors(not just a fanciful video): The charge of the battery, the weather, is the soil wet/dry, or soft/hard? Your bodyweight? If over 220 pounds, e-bikes are gonna give ya very minimal assist up a hill in turbo-mode. Lastly, the physical shape you are in. I find the Yamaha PW-X2, to get me up any steep incline & home in any weather, with (so-far), minimal problems(forgetting to re-charge). Most bike reviews are about giving a product decent review, to keep-on getting stuff to review. Trusting social media for products, is ill-advised.
The vague title of the video already made me suspicious that the true winner would be the Bosch in the end. :-D Honestly, i think its really time to take the Bafang M500 into a testlab for some detailed measurements. I suspect that neither the original M500 nor the improved one they send you is actually capable of reaching 95nm of torque. While i admit that Bafang may still be dealing with a poorly written firmware here, i rather suspect that the M500 is actually a 75 to 80 nm motor. I would really like to see how it compares to a Shimano E8000 with 75nm. I have a certain feeling both will be pretty much eye to eye rather than Bafang ending up as the winner. Now im not saying the words "advertisement scam" here just yet. But...... ;-)
Hi Rob, is there any chance you could share with me what brand of glasses/googles you are wearing when you were on the bikes during the comparison of the two motors ?
Just ordered the Dengfu E06 it was a bit weird making a PayPal purchase of 4.6 grand based on some texts and pictures. I really like the idea of a fat tire high performance ebike.Hope it doesn't disappoint. I bought it based on the cheeb video you posted Rob ! Is the new m500 more powerful than Bafang M620 G510 1000W 48V ? That's what is coming on my EO6
Nice to know I chose a good motor (Bosch) even though its not user configurable. I would have liked an eco- and eco+ as well as eco which would be great for flat(ish) trails and wind resistance/assistance. Otherwise trail and emtb are excellent adaptive modes and turbo, though a bit snatchy, will get me up anything.
It is sometimes supplied with a thumb throttle. But if you built one up and wanted it to comply as a "pedelec" (ie, be legal without licence plate/insurance) you couldn't install it. They work as pedal assist. You pedal, it assists depending on how hard you pedal.
bro, is the front hub motor better value for money n with less maintenance problems than a mid n rear hub one ... Is it true that the internal gear or belt in the mid hub motor will wear faster n the external bicycle gear will also wear faster when a mid hub motor is used ..
Rob, I thought the Bosch Gen 4 version of the CX was a 750w output motor though, could explain why it seems to get up the hill faster than the Befang M500 500w system. I know that the motor's torque is what drives the thing, but power delivery, wouldn't that also play a factor in the two compared? I mean it's a 250w difference between the two, which would equate to a bit more power delivered to the rear wheel and maybe the torque curve is different in a larger motor. I mean it's a good comparison.. pricewise they are roughly the same, but power comparison, they are not. And I would think the Bosch would out preform the Befang anyways because Bosch had been building small torquey motors in drills for decades, SO I wouldn't be surprised the Bosch corporation has fine tuned this motor over the years. I guess it all boils down to "you get what you paid for" as you can't expect a Ferrari performance for under 1k these days w/o some DIY and recycled parts.

I think its something to do with the seat tube angle. Chinese carbon frames have a fairly slack seat tube angle. That is why whenever I borrow my friends ebike with exactly the same motor. I always move the seat forward to steepen the seat tube angle which helps smoothen up the climb.
i have never run out of power on a climb with the Brose. When it gets to vertical the front lifts up or the wheel spins out. the motor isnt the failure point.
What about the gearing where they both identical
I have this motor in my Cannondale Neo Lefty 3 and I agree, it's a beast. Tons of power in turbo.
Nice
Thanks for the video 👍
Great video and a great cause 👍
Thanks for showing, if bike sales keep diminishing a vid on making older bikes more modern and better suspention,ect. Wouldnt be a bad idea. I'm putting a cascade link on levo and mulleting it. I drool over Gen 3, but you can't get one here, and they don't offer the model I want yet.

Love the spray job Rob , wicked that cheers Shane uk 🇬🇧
great vid buddy
Back to the drawing board for Bafang. My biggest concern is longevity. Motor drives are no cheap and I wouldn’t fancy a rebuild or replacement every 2-3yrs. As for trash free trails, the answer is simple. All those using them respect them and take your litter home!
Where Bosh is a closed system,.so all parts need to be bosh/manufatcter approved to work.If on chip fails ..you need to buy specific expensive parts,lSpecial dealer only software to adjust settings.
Bafang gives you more freedom.Special on bataries and displays,and custom settings.
Bosch Rob all the way😀💕👍
Excellent music choice and use.
Thanks!
I knew I noticed that hill climb from somewhere, you used a TQ motor on it from a previous video. Ended up buying a Haibike Flyon bike after seeing that video, now living on beans n toast for the next few years or so :)
See if you can get hold of the M600s motor (EU legal special version of the M600) It will beat or match the Bosch motor.
I have almost the same setup with the same frame but the M600s motor. I've never seen a hill where I have any trouble getting up unless I loose grip og flip the bike over.
Hi Rob
Would you like you to do a review with my Dengfu e10 with m600 motor against your trek and new spes s works ,have a trip up to peaks it’s on my doorstep
cheers john
I wish you still had the CHEEB so that the hill climb could be retested. Based on your build video and photos on emtb, it looks like the Trek Rail 5 had a gearing advantage of anywhere from 9% to 13%... No wonder it beat out the CHEEB/Bafang.
How does that M500 compare to a BBSHD?
Was this an apple to Apple test though? Motor gearing, bike gearing etc.
If Bosch lost it would have been embarrassing. This has shown they are worth paying more for
You need to run this test with a throttle. Your feet create an unmeasurable variable.
Totalmente de acuerdo 😊
Fab video thanks - an honest and true reflection more NM's doesnt always mean better motor
Hey Rob Rides Emtb! Thank you for the nice motor test video! Were both bikes in the exact same gear ratio? Ride ride ride!
Rob you need to try seat down and sitting and leaning forward.
Then you load the weight on the rear wheel. Maybe the befang is to powerful and is judt spinning up
What happened to the cheeb v2 video??
If your on a budget it's awesome. Perhaps down the road they will provide something even more powerful based on their market share? One can only hope.
It's great to see someone finally do a legit hill comparison. It would be great to see the EP8 and Bafang Ultra with Archon X1 (Watt Wagons) controller. EP8 won't do much but that Archon is rated at 160 Nm. Hope the next CHEEB uses one of those!!!
ep8 nothing special, bosch g4 will eat it on hills
So it seemed to me that the Bafang bike could not climb something that a regular bike could do in short gear. I climb stuff like that all the time, just at the limit of traction and balance. Did I miss something?
Personally I'm more interested into comparing BBSHD versus Archon engine. Both seem to produce 160nm from engine. Gear ratio must be usable for climbing and high speed on road.
What was the weight of both bikes? and what was the gearing? Also what batteries were in them and were they both charged to full? were they the same? & what are the costs of each ??
This is what also interests me.
Ah, even though the advertised Nm torque figure of the Bafang is higher, the sheer finesse of torque delivery of the Bosch is just top-notch. Good comparison! I have to ask if you'll entertain the idea of testing those built Bafang motors with an aftermarket controller? Innotrace is one of them
Not apples to apples though as the gearing was not the same.
I suspect that’s all down to the torque sensor in the Bosch.
Or more likely Bafang just lies in specs, like too common for Chinese production.
Bosch outputs more Watts than Bafang. Not sure about Bafang but Bosch is ~600w continous.
@@finrider9924 the performance line cx doesn't deliver 600 watts ever. Even the s-pedelec version won't go higher than 350.
Your chain ring on the bafang and bosh the same?
Really look forward to bafang to build a bike around their motor by themselves and come to this location to have a try.
Hi. Great vid. Where did you purchase the vomponents to make the bafang bike. Items like the frame and motor.
Many thanks
Bafang are already putting the final touches to a version 3 which should be winging its way to you very soon. Hopefully...
are they going to make new motor?
bit off topic but the pearlescent paintwork looked great. A few details about it please:)
Cool Tschaikowsky 1812 one of my favorite Classics
Dowt free aeroports organisation invites you to donate we gonna keep that jungle cleans !!😂😂😂
Well done, Thanks!
So basically: Ya-get-what-ya-can-pay. And going uphill depends on a few factors(not just a fanciful video): The charge of the battery, the weather, is the soil wet/dry, or soft/hard? Your bodyweight? If over 220 pounds, e-bikes are gonna give ya very minimal assist up a hill in turbo-mode. Lastly, the physical shape you are in. I find the Yamaha PW-X2, to get me up any steep incline & home in any weather, with (so-far), minimal problems(forgetting to re-charge). Most bike reviews are about giving a product decent review, to keep-on getting stuff to review. Trusting social media for products, is ill-advised.
good, so you make great bikes, could you make a Orbea Rise for me, please ?
m500 36T-46T 27.5
Gen 4 34T-52T 29
So Rob's test is pointless when Bosch equiped bike has about 13% lower gearing?
The vague title of the video already made me suspicious that the true winner would be the Bosch in the end. :-D Honestly, i think its really time to take the Bafang M500 into a testlab for some detailed measurements. I suspect that neither the original M500 nor the improved one they send you is actually capable of reaching 95nm of torque. While i admit that Bafang may still be dealing with a poorly written firmware here, i rather suspect that the M500 is actually a 75 to 80 nm motor. I would really like to see how it compares to a Shimano E8000 with 75nm. I have a certain feeling both will be pretty much eye to eye rather than Bafang ending up as the winner. Now im not saying the words "advertisement scam" here just yet. But...... ;-)
you throttled something from the bafang motor when programming🧐, it would be nice to see how the settings were🤗
Thank you
bafang 500 is only 250w， try 1000w bafang it will be completely different experience
Very good video 👍🇫🇮👏
Hi Rob, is there any chance you could share with me what brand of glasses/googles you are wearing when you were on the bikes during the comparison of the two motors ?
A cigarette at 4:20 would have been appropriate. BTW, it was good for me as well 😉
Just ordered the Dengfu E06 it was a bit weird making a PayPal purchase of 4.6 grand based on some texts and pictures. I really like the idea of a fat tire high performance ebike.Hope it doesn't disappoint. I bought it based on the cheeb video you posted Rob ! Is the new m500 more powerful than Bafang M620 G510 1000W 48V ? That's what is coming on my EO6
That's it not bad I paid $14,000 for my specialized levo turbo comp
No G510 is Max Torque: 160N.m
Hah after reading about the 14k bike. Mot bad mate
Surely if you did the climb in first gear first time on the Chinese bike it would have made it?
Nice to know I chose a good motor (Bosch) even though its not user configurable. I would have liked an eco- and eco+ as well as eco which would be great for flat(ish) trails and wind resistance/assistance. Otherwise trail and emtb are excellent adaptive modes and turbo, though a bit snatchy, will get me up anything.
I am about to buy a bike with the Bosch motor. Have you defeated the speed limiter?
it is user configurable, but you have to install the Nyon control unit to do it
stupid question but can you just ride this like a normal E Bike and no pedalling at all??
It is sometimes supplied with a thumb throttle. But if you built one up and wanted it to comply as a "pedelec" (ie, be legal without licence plate/insurance) you couldn't install it. They work as pedal assist. You pedal, it assists depending on how hard you pedal.
@@pigshed oh thats interesting cheers mate!
Yes, sure.
My Bafang 750 watt has both pedal-assist and throttle.
No pedaling needed if you use the throttle.
I'ts sad that trashfreetrails even exists.
If people would only take home what they bring to the trails...
Nevertheless, good cause!
The Fairest comparison would be The latest Bafang 510 ultra ( not the older Bafang 500) 🥳👍
I personnaly think that new motor upgrade he got was the M510
As a mechanic that works on ALOT of bike, I just dont feel like bafeng will ever compete with the engineering of bosch.
the fact the trek over powered the bosch was not a surprise? 85 v 90, however Bosch G4 is an awesome motor which will prove to be hard to beat.
Would have been cool to do a retest with the new Bafang M620 with 60V Battery.
bro that climb was real
bro, is the front hub motor better value for money n with less maintenance problems than a mid n rear hub one ...
Is it true that the internal gear or belt in the mid hub motor will wear faster n the external bicycle gear will also wear faster when a mid hub motor is used ..
I bought and installed my 750 bafang mid drive. Taking any hill no problem.
I need those wall lights
Rob, I thought the Bosch Gen 4 version of the CX was a 750w output motor though, could explain why it seems to get up the hill faster than the Befang M500 500w system. I know that the motor's torque is what drives the thing, but power delivery, wouldn't that also play a factor in the two compared? I mean it's a 250w difference between the two, which would equate to a bit more power delivered to the rear wheel and maybe the torque curve is different in a larger motor. I mean it's a good comparison.. pricewise they are roughly the same, but power comparison, they are not. And I would think the Bosch would out preform the Befang anyways because Bosch had been building small torquey motors in drills for decades, SO I wouldn't be surprised the Bosch corporation has fine tuned this motor over the years. I guess it all boils down to "you get what you paid for" as you can't expect a Ferrari performance for under 1k these days w/o some DIY and recycled parts.
