I have a fairly new bike that for some unknown reason, the entire crank that the pedal is on just falls off while riding.
It gets loose then just falls off, crank and pedal. I think it's because the little square fitting is all carved out into a circle a bit, but if anyone has any advice on what I should do, let me know. Because I will most likely just get a new bike unless there is some solution I just don't know about.
