Hello everyone, i have problem with my tongsheng motor.
My motor case cracked because it wasn't fastened properly. I replaced the case and now I have a problem. While I am turning the pedals without the motor running It turns very heavy and noisy, as soon as the motor starts, everything is great. Everything looks good to me and nothing is worn out. I have the feeling that on the new case the holes for the motor shaft and the blue gear shaft are not in the right position. Has anyone had similar experiences?
