Q&A for How to Fix a Slipped Bike Chain

There could be a number of factors influencing this symptom. Most likely, this is a result of the pawls in your freewheel or freehub body being dirty or corroded. Disassembling and servicing, or even applying lubricant, can assuage this symptom. If lubrication is not the issue, you will likely need a new freewheel or wheel. Occasionally, an improperly reassembled hub can cause this issue. If you recently serviced the axle bearings in your rear wheel, take it back apart and make sure you reassembled it correctly.

Check for chain ring (the big gear) and cassette alignment, then check and see how old your chain is. If the bike has seen some use and abuse it is likely in need of a new chain. If you have really neglected maintanence, it is possible that you may need an entirely new drive train.

1.) Turn the bike upside down or hang it from a bike stand. 2.) Note what gear the bike is in. 3.) Push the rear derailleur arm towards the handle bars to get slack on the chain. 4.) Use your other hand to slide the chain back on the right gear. 5.) Slowly pedal the bike with one hand.

To 'pop' the back of your bike you first need to learn how to bunny hop. But at the most basic level, to pop the back wheel you have to jump without leaving the pedals as well as lean forward and load up the front tire.

You just replace it like any other bike. If you are uncertain or this is a new concept, it will be beneficial to take your bike to a bike shop and ask if they can teach you how to fix your chain. The nice thing about bikes is they generally all use the same chain and drive components.
