Somewhere I read that early boards may have this problem, may be it is board, but I recommend found someone with work display to connect it to check. I have 2 m510 with 3000km on each - work good, so it is not such "fragile". In your theory with overheating main problem should be with MOSFETs...

Hi, have you 48V on motors input from battery? try to reconnect all cables , main cable from motor to display on motor check button that enable battery output (not on all models) not correlated things: display switches off and the chain jumps of the chain ring chain will not affected by...

Hi, see attach files

My father ride Dengfu E10 , 98kg, no jumps but hard terrain, like you say "big amplitude lines". Frame still good. I ride same E10, but my weight 77kg.

62% = 25km/h if total limit is 40km/h

Hi, not agree, without throttle, only on pedals if I set Speed limit in % ~ = 25 km/h it will cut off motor when you get 25km/h no matter what gear or cadence. But I do not like it, I can get 27km/h on foots without motor and I hear strange sounds from motor when it on-off-on-off ... After year...

On top image from besst tool - "Speed Limit %"

Hi, if "switch display off and on again it works like usual and dirvetrain support is ok again" I think problem with controller board, may be you should reflash FW or replace it ... next to change is more expensive torque sensor - but if it sometimes work normal I think it is normal

Anything one man design another man can repair, main problem is available of details, datasheets, FW, programs, IC. When unit not detailed - it only means manufacture greedy.

Hi, read my post In your case I think problem is - with idle state with no force on pedal it should be 750mv as you can see here for example But you say 850mv - it like you press pedals from start - motor will not work. In night rides sometimes when I want to correct lighting I can suddenly...

Hi, motor is simple, once you open it, illustrated information you should find disassembly video on YouTube, it more simple than text version. Bafang M510 motor teardown video

Epic jump 👍 M560 motor, as I read, noisy, but no nylon gear and more power than m510 If you don't buy you don't know will it broke or not ;) I think if price is good it is not bad idea, you get all components and if some problems with frame you can contact Dengfu and ask for buy only 1...

Thank you for your kind words. Dengfu e10 specify 150 rear travel, but I think it is not more than 140 with 210x55 rear shock, I never measured it myself. I always leave some space for safety frame travel (I mean in full travel condition the crossbar of the links should not reach the seat...

Hi, Yes, sometime it can be usefully.

One day motor stop support at the middle of trail, disassembly it at home and found signs of water inside. Magnesium chassis also damaged and corroded. When I take torque sensor it was wet with white signs of water on metal and on sensor sheet. My first attempt to recover it was failed because I...

something :eek:

1200km of mud, wet, snow - it stop support because torque sensor was wet, when I open it fail 2 bearings - 1 bigger diameter bearing and 1 upper on one-way assembly, not main one-way itself. 2nd motor - not 2nd, I have 2 fat bikes with 2 motors, so I not correct say about it noise - not hear...

I think you want to buy full suspension frame, but weight cons stop you. :sneaky: just look Dengfu E23 Full sus Fat for USA they BIg Fat

sorry but wireless diagnostic always incorrect, you can try to check bearings for free move, check central gear for one-way move \\ black grease is black from factory I open my motor with 0km on it, it is specific grease I think with graphite for better gear work, talks about white grease ok...

Just order this parts from aliexpress, plug&play, not wait for any warranty :LOL:
