Hi Guys,
I have a Tongsheng TSDZ2 350w engine on my cargo bike. With fully charged battery I am experiencing, that my motor is beeing unstable in it's tourque. It's in all 4 assist modes when pedaling normal. It's kind of cutting powerassist ON and OFF every second or so. If I pedal HARD, I can get assist all the time. The problem can sometimes be fixed by restarting the display (vlcd5) or battery. It will then give me a normal assist again for some time. It has increased a bit over the last 2-3 month and today my display could not show the speed either (maybe another problem).
The battery is charged, speedlimit is OFF, and I have checked the magnet and sensor on backwheel. Seems to sit perfect.
Any suggestions on how to 'debug' this..
Info:
Motor age: 1 year
ODO: 2750 km
Battery: 36V, 13ah – 468wh.
Battery age: 2 years
Thanks in advance
Cheers
