What should I do if the bicycle chain often falls off?

There are two possibilities: 1. After riding a bike for a long time, the wheel screws are loose. Unscrew the screw and move the wheel backwards appropriately. According to the length of the chain, don't push too hard or too fast, and then tighten the screws. It is best to check it regularly.

2. It may be that the bicycle chain is loose and long after riding for a long time. If you can repair the car yourself, you can take a pick off the chain. If you can't handle it yourself, or simply go to the garage to get it shorter, it's ok.
