Weird bafang acceleration problem. Is the controller broken or not :/

[regan03]

Problem: Acceleration decreases immediately after pushing the throttle/pedalling.

Video (the throttle is pushed constantly for the first half of the video)

Acceleration decreases immediately after pushing the throttle/pedalling. Although I dont stop pushing the throttle nor pedalling. As it shows in the video.

Acceleration works properly (for a second) only when the chainring is stopped. If the chainring is already moving, pedalling/pushing the throttle doesn't do much.

This issue started manifesting from time to time at first and then more and more often. Now it's permanently stuck like this unfortunately, I can't use it


What I tried to fix the problem:
- bafang software. Modified a bunch of settings several times with no success though.
- opened the motor and reasembled it (i'm not a very technical guy lol).

The motor is BBSHD 1000W 48V

How can it be the pedal sensor since the same issue applies to the throttle not only to pedaling? This should exclude the pedal sensor, right? Or am i wrong

I can't see the video, but need clarification. What is the case where the chain ring is moving without throttle or pedaling? Is it moving when not under power?

Acceleration works properly (for a second) only when the chainring is stopped. If the chainring is already moving, pedalling/pushing the throttle doesn't do much.

I was going to guess a throttle or throttle connection issue, but the chainring moving by itself is odd.

snap ring missing?

Oh what I was refering to was the 1-2 seconds the chainring continues rotating (then motor keeps running) after you stop pedaling/throttling (it doesn't stop the split second you stop pedaling, continues for a bit after). You know what I mean? It's a normal default setting in the controller no poltergeist involved lol.

I've reuploaded the video. It should work now.
