Got this used begode a2 a few weeks ago. It was already in less than good shape and I dropped it a few times. It makes this vibrating, friction noise when I'm just going forward and I don't know what's causing it. It comes and goes randomly but it usually disappears whenever I'm on an incline or decline.

I've tightened all the bolts i could see on it without taking everything apart, and I checked for any debris or bent parts and couldn't find any. The wheel spins freely when it's off, it only makes this noise when I'm on it and moving and even then it's inconsistent.

Any ideas would be appreciated
