There are many possibilities for a bicycle chain that keeps falling off.
Here are some ways to deal with it:
1. Adjust the derailleur: If the bicycle is equipped with a derailleur, it may be that the derailleur is not adjusted properly, causing the chain to fall off. This can be solved by adjusting the limit screw and cable of the transmission.
2. Adjust the chain tightness: If the chain is too loose or too tight, it may easily cause the chain to fall off. This can be solved by adjusting the tightness of the chain. Generally speaking, the tightness is moderate and a gap of 1-2 cm can be left under the chain.
3. Replace the chain: If the chain is worn or aged, it may easily cause the chain to fall off. Consider replacing the chain with a new one.
4. Replace the sprocket and flywheel: If the sprocket and flywheel are severely worn, it may easily cause the chain to fall off. Consider replacing the sprocket and flywheel with new ones.
5. Check whether the chain is installed correctly: If the chain is not installed correctly, it will also cause the chain to fall off. You can check that the chain is properly installed on the sprocket and cassette. It should be noted that when dealing with the problem of bicycle chain falling, you must pay attention to safety and avoid accidents while driving. If there are other problems with the bicycle, it is recommended to seek professional repair services.
