Hello, help needed, I couldn't find where is a problem.
Motor: 350W 48V no brand Chinese motor.
Millage: 2000 KM
Issue: Motor/wheel spins fine when wheel lifted, but when I put the wheel on the ground or drive bike,
motor/wheel makes an ugly rattling sound, especially when just starting to accelerate, but it looks like it doesn't
affect torque or total speed.
What I already did/tested:
- tested hall sensors, looks like all working fine (switching between 5v and 0v).
- disassembled wheel and applied new grease, didn't detect any broken parts (from internal gears).
- removed chain, rear disk brakes, to eliminate possible side sounds.
I find out that the rear cassette slightly moving, can it be the wheel motor axle bent, and this why I get that rattling sound?
