    Bafang Rear Hub Grinding and wrong speed

    Thanks, I'll give another once over. I was riding the bike last night for an extended period of time. It's no so much a grinding noise but a louder whirling noise at low speeds. Goes away at high speeds. Cheers

    Sorry what do you mean by finding phase and hall assignments? How will I know which is the right combination?

    Bafang Rear Hub Grinding and wrong speed

    Opened the hub and wires are all intact and looks quite clean. Motor has hardly done any miles. White wire is going to the SP point which looks good. I'm out of ideas.

    Bafang Rear Hub Grinding and wrong speed

    Thanks. I'm going to check out the cabling again today. I suspect it's internal to the hub as the other motor I tested on the bike ran fine and showed an accurate speed.

    Display problem??

    Hi there, yep, that's the display i have. The other data is there and when I swapped over the controller I did check the connections. I also plugged the display directly into the controller bypassing the extension splitter cable, same problem.

    Display problem??

    Hi all, I have an ebike running a Bafang 250w motor, DMHC TC480 controller and dmhc display. For some reason the display battery indicator is blinking on one bar and the bike does not function. I've swapped out the controller and battery and still no luck. I know the motor works as I've...
