"Popping" as in, making a loud noise, or actually coming off?

If it is making a loud noise, its just increased tension on the chain. Nothing really to worry about.

If it is popping OFF, theres a multitude of things that could be causing it, but the most common is a bent cog spike (the little teeth on the gear.)

The latter can be a LITTLE expensive, but much cheaper than buying a new bike.


Either way, one should always practice proper chain maintenance. For example, don't leave your bike out in the rain, and if you DO, don't leave the most important parts exposed. Towel the bike dry if it gets wet.

Chain care is really easy. Just buy a little bottle of chain lube (this stuff), turn the bike upside down, and pedal SLOWLY, putting a drop on every link. Pedal it through a few times, gently place a rag on the chain (hold the rag) and pedal the chain through the rag once. Easy as pie, will make the chain flow like butter, and should stop any creaking noises you hear from the chain itself.

Remember!~ A bike chain is like the inner mechanisms of any machine. It needs proper care and love just like anything else (only more so, because it is exposed)

*PS* You don't need the Pedros stuff, its just what I use. You can pick up lube at any bike shop or even at Walmart prolly. Just make sure it says "CHAIN Lube" and you're a-OK.
