I was riding the bike today and all of a sudden after riding up some steps which I always ride up, my cromotor makes some kind of grinding noise. I think there is a slight loss of power, but it isn't a great loss of power.
I can still hit 40MPH.
It seems to do the grinding noise on hard acceleration, either at speed or stopped.
I have a video of the grinding noise it is making.
What do you think it could be or what should I check?
