E bike fault

[Peter S]

Hi I purchased a bafang 1000w mid motor about 18 month ago & only done 650 miles on it, I got on it for the first time this year. On riding the bike when pedaling some times it jumped forward.
So I have replaced the bid steel flywheel & clutch plus the nylon gear & regreased all appropriate internal parts. Got on the bike for a test run but unfortunately the problem was still there, can anybody help me on this matter please.
Thanks Peter

Apparently, as there are no replies, others are struggling with what you are saying as much as I am. Will you tell us more about this please, maybe add some detail?

"On riding the bike when pedaling some times it jumped forward."

Also, can you be more specific about the 1000w Bafang mid motor?

Is your Bafang motor a Canbus or Uart protocol?
If you want to provide the info from the spec's tag on the bottom of the motor and controller, I may be able to tell you which protocol you have, help with your problem.

Tia,
Don

Peter, have a look at the setting, *.el files in my sig. If you have a BBSHD you can make programming adjustments. Several of us have turned the BBSxx series motors and many of the files and their setting will provide for a better ride.

What about a wheel magnet alignment issue making it sporadic? That would be an easy fix.
