My (MAC) hub motor suddenly stopped engaging with the bike gear sprocket. The motor runs with throttle and sometimes the gear sprocket engages with the hub when I can pedal power the bike. Otherwise, when I pedal, the gear sprocket does not engage at all. I used the throttle mostly and used pedal whenever it engaged to get home. After I got home, I removed the rear wheel and checked the gear sprocket. I can spin the sprocket both froward and backward without engaging the motor hub.
Before I open up the motor cover, I wanted to get opinions of someone who might have experienced this and guidance on how to fix this problem.
Could someone please help me? Thank you very much in advance.
