I keep getting a squeaking sound on my M20i. I thought it was the front wheel but I have narrowed it down to either the rear disc brake or the motor. I think it is the motor. It usually doesn't start until 5-10 miles into my rides. Today I stopped when it was getting really loud and found a piece of zip tie next to the motor so I pushed that more to the side and cut it off when I got home. Still squeaking.
I have loosened the brake caliper and pulled brake lever and re-tightened caliper twice in case it was the brakes. Has anyone else had this problem? Was it the motor? Is there a way to add some lubrication to the motor somewhere? Here is a picture of the zip tie I took off and a link to a video where you can hear the squeaking.
