have an issue with my ebike where the hub is making weird grinding noises. I hoped that some here had some input as to what the cause could be.
here is the problem:

Under load the hub makes this grinding noise, it only happens when the hub has to work a lot. So on stand still and going from low to high speed, it will make this noise. Once i reach a high speed (around 20KPH) it is quiet and works flawlessly.
- I replaced the controller with a better one
- Running sensorless
- Nylon gears are new and replaced
- Magnets not loose
Currently my suspicion is currently that I have a light short somewhere in the hub causing the phases to go out of whack. Since the engine does spin and it only happens on very high load. However I would like some more input in case I'm missing something.
