Just earlier today after I got back from a ride, I can hear what I would describe as a squeak with the motor off and either pedaling or just rolling the bike forward or backward. What could be some causes of this? Seems like it's getting louder too. My guess is it's coming from the small drive gear under the clutch cover but I'm not totally sure that's where it's coming from. I will try to put up a short video clip tomorrow. Any help is appreciated.
