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 .
Is the bike still available,,do you any freys e bike. Or how bout a long range daul battery 1000 to 1500 bafang ultra emtb call me interested in buying a mountain e bike long range with 160 torque , 27 inch or 29 inches rims.....18 inch 19inch frame,,,,,,asap. 6107153704 chris
Fine , but are we comparing apples to apples here? Torque and power output have a lot to do with voltage, current and gearing. First are the gear ratios identical? Second what is the measured voltage of the two batteries? Third, what is the current out put of the two batteries? If one has a 30Amp BMS and the other has a 40Amp BMS then that is not equal. Software may be another factor. You are using the pedal assist on both bikes which may not be equal. I would turn off the pedal assist and do a throttle only run and then a throttle run with you pedalling. Keep the pedal assist and its torque sensor turn off. My cheap Cyclone motor with a 48V 40A BMS will usually try to wheely over backwards on steep hills and will only stall the BMS after long extremely steep sections that are pretty much unridable to begin with. Your test is not very scientific and needs to be redone. The rated torque of these motors is also a product of their internal gear reduction. We all want to see what the best kit is but you have to be fair with your testing and I think you have not proven that.
@@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!
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
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. Accidental when the wind catches a scrap and you just can't catch it, not enough to fill your sock. It sickens me to hike or bike in the beautiful outdoors and see everything from beer cans to coffee cups to wrappers of every sort. Pack it In, Pack it Out....No excuses!!!
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...... ;-)
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
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.
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 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.
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
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...ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-X2IPtda_LFo.html
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.
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.
Totally not accurtae have ridden both bafang smashes a bosch uphill if your gearing and battery are correct. Bike geometry everything. Cant compare apple to orange.
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.
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.
Why does he not confirm that wheel size, his selected front and rear chain rings during the test, and the crank arm lengths were all exactly the same on each bike during the two tests? Without these being the same, the test is completely useless, and so is the video.
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.
Yeah but Bosch is owned by a non-profit charitable foundation so that any profits they make go to good causes rather than making rich shareholders richer.
It could be the battery letting down th Bafang motor. Typically cheaper Chinese batteries are made with lower quality 18650 cells and dont have enough nickel spot welded between the cells. This raises the resistance and reduces performance. performance.
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.
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
🤣🤣man those are really weak specs my bolt on mid drive bafang bbshd on 52v 41.4ah 30a makes around 1500 1600 continouos watts STOCK!!!!! easy 70kmh 45mph on THROTLE ONLY 170NM torque💪🏻💪🏻
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 ..
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.
Tanta diferencia no tiene sentido, 1 motor de 500w Bafang = 500w Bosh = 500w ACME = 500w x. La diferencia está en la programación del motor, voltaje, peso bicicleta y desarrollo
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.
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
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.
“My motor is better than your motor” !!!🤦♂️ Leg power boys! If you want to be wholesome, green and healthy….ditch the motors and find smaller hills. I’ll stick to petrol. 😁
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.
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.
im thinking putting a bafang e motor mid drive on my Santa Cruz V10 but i dont know how many watts should i buy 750w or 1000w, can a 750watts run my heavy bike?
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 ??
I can’t understand why anything over 85nm is needed, my cube with a Bosch 85nm can climb anything if I can stay on it without sliding off the back, and it will hit the 15mph speed limit with ease. Seems a bit pointless to me. Same with batteries, how big do you need, once you can get 50miles like mine can having much more really is a bit pointless, at what point do you just pedal a bit more. What’s needed are less gears and more robust drive trains and brakes pads which last longer than a few hundred miles.
I had Bafang M500 for about two years, firts one lasted 800km. It is not that smooth as Bosh CX or Yamaha ST at all, in my opinion is not as powerfull as these two. I bought new bike with yamaha and this motor is miles away ahead. Bafang is good for money but no better than competitors.
The price to performance is garbage on bike parts, especially frames and motors. I went and looked for similar alternatives to bike motors/ frames and found that you can get minibike frames for around 200$ but a simple steel bicycle frame cost over 8003, when I checked motors I could find the same spec motors in a conversion kit for scooters/mopeds for around 150$. I will let them get away with a overpriced motor since they went full custom but I can't excuse the frames being stupidly expensive, they are not a complex part and they are very easy to streamline and automate.
Le test de monté n'est très pas objectif. Trek Rail 2021 = 12v (10-52) avec T36 en 29" Bike chinois = 10v (11-46) avec T36 en 27.5" Le braquet n'est pas le même.
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.
The bigPROBLEM with Proprietary Systems like the Bosch motor is that they require a proprietary battery (usually cost 50-60% more) and the Bosch motor (with a chip) will not work without a Bosch battery (with the same chip).. the motor and the chip talk to each other.. bigQUESTION... what happens when bosch decides they are no longer going to do ebike systems...? What happens if they are sued out of business like Bionx when GE sued them over breach of contract..? Now anyone with a Bionix motor that needs a replacement batter is out of luck... the motor is no good without the proprietary battery... I like the non-proprietary systems like Bafang BBS02 and BBSHD.. You can always find parts, and you can always find a downtube battery that will work.. And they are 1/3 the cost of the Bosch...
THE BAFANG issue is the fact YOU can't even peform a crankFlip Because of the resitance of the bearings when back peddling. It pisses me off I like to do little tricks before riding to get warmed up and my Tuned M600 can't sping backwards fast enough to do a crank flip.
Can you get rid of the crappy M500 and compare the Bosch to the BBSHD with 1kw nominal, 1.5kw peak and 160nm torque? My BBSHD will keep the power output pinned at 1500 watts if I keep the throttle mashed.
EU regs are lame. My 2018 vintage bbshd makes 160nm of torque with a stock Luna 30 amp controller. My commuter w saddlebags and racks will crush either of those pigs.
Now if these motors cost about $50 that would be worth it..$1,500 I can get an older model sport bike that does 145 mph with endless range..Anything over $1,000 for a top of the line electric bike is just absurd and a rip off m
I don’t know about bikes. But my wicked thumb rat has a bafang 750watt. It’s no mountain bike a chopper I bet I make it up that hill no problem. Throttle alone hits 28mph. 37peddle.
One thing I don't like about these videos is they compare the rolls royce of a motor against the Jaguar of motors, what thje need to compare is facts it is very hard to buy a Bosch kit as their motors you get if you buy a bike and are not D.I.Y kits and price are 3 times that of a Bafang. The cheapest eBike with a Bosch motor brand new is £1,800 and you can buy the same cycle without a motor fitted for £300 and a Bafang motor for £420 or even a little less. So you have £720 to £1,800 I would not expect any comparrison that is why their is a market for ready mady cycles with fitted motors but here they are hard to get and the cheapest competible bike for me is over £3,000 otherwise I would have to wait upto a year for a £1,800 in my sizw or buy second hand. The Benefits for kits you get the right size cycle and withing a week you have an electric bike for under a £1,000, otherwise you can wait upto a year and buy one your size for £1,800 or get one your size for over £3,000 withing a day. Most mid drive motor cycles for sale right away are 46cm frames and they only have them available because there is very few small adults so really how can you destroy something that is cheaper, quicker to buy for a fraction of the price? I would of been shocked if the Bafang motor out did the Bosch motor because the price difference is tremendous over double the price.
What's the sealing like around the crank shaft? Bafang mounts the controller directly to the engine cover, and the seal around the cranshaft is essentially a dust cover. Any idea how well the sealing is on the motor, as water intrusion is the biggest problem for all ebike motors.?
This dude keeps saying power and than says motor's torque. Nm is a unit of torque. With some gearing you can achieve pretty much any torque, specially with a mid drive. But what's the power of those engines? *Powerful motor* yet no mention of actual power. This is stupid.
Car torque nm ratings might be vastly smaller but cars don't need to produce much torque because the engine spins at 7000-12000 rpm which produces huge horsepower, and low torque can be mitigated with gearing. Tons of torque is useful for tractors but race vehicles need tons of horsepower not torque.
I know I'm going to stir up a hornets nest here, commenting out of context, and admitting to be Old School....But why not shave off a few kilos and a few thousand dollars. And get a bike without a motor and use good old muscle power. After a few tries you'd probably make it up the hill trading off the extra the weight for a higher level of fitness! I did the electric bike thing a number of years ago. But once the novelty wore off. I was back to Pure Pedal Power......
Hi Rob i would like to come in contact with you. I work for bafang holland and like your movies a lot. Maybe i can support you with some nice a powerful software for the m500 of m510.
I hat the two motors, After seeing your video, several of us think that your technique with the bafang is poor, first of all it is not climbing with maximum power, the torque works differently and I have achieved much harder slopes. Your test is poor and misdirected.
I understand that torque is paramount in hill climbing, but does that justify calling newton-meters "power" when it is really torque, which can be multiplied by gearing?
Γεια σας μηπως θα μπορουσατε να μου πειτε ποιο ειναι το καλυτερο μοτερ για φατ μπαικ.που να βγαζει 160 νιου μητερς παουαρ.και αν μπορειτε σας παρακαλω να μου πειτε και τιμη σε γιουρο.σας ευχαριστω πολυ.και περιμενωαπαντηση σας.
I ride a Bafang and i could reach any peak. And reach more than 25kmh of course... And finaly you can adjust that motor with a simple USB and your laptop
