Hi,
I have a strange problem. I came home yesterday with my ebike and everything worked fine. Plugged the charger in and went to sleep. Today the BBSHD isn't working anymore. The display turns on, battery is at 58.6V almost full. When I start to pedal the BBSHD won't assist. The throttle on the other hand will move the chainring about 0.1-1cm and then suddenly instantly stops. It's like there is something blocking it and the motor / controller tries to protects itself by shutting down - like if I'd use the throttle while braking.
Normally there is no error. But after switching it on and off multiple times I've spotted error 12H. But it's rare.
What can I do? Do I have to take it apart? Can the controller be defective even if the display works and no error is shown?
PS: There is and was no brake sensor connected. Also no speed sensor.
