Greetings.
I recently assembled bbs02 500w 36V motor on my bike.
At the end of first test ride which was around 10 km i noticed strange whistle like sound from motor.
Sound is there only when turning pedals. While using motor on throttle there is no strange sound.
Sound is present even when the motor is turned off. It is definitely coming from motor, i think from pedal axle part of it.
Motor works fine, there is no heat problem or other problems whatsoever just that strange noise.
I removed motor from bike and noise disapered and after i returned it to bike gradualy the whistle noise returned.
Can someone give some advice what can be the reason of this strange noise.
Here is the vid of the noise:
