How to Fix a BMX Offset Chain

Unlike a mountain bike, a BMX bicycle is a bare-bones unit. There are no gears to switch to, only the pedals to propel motion and a brake to stop you. The pedals are connected to a chain, which acts as the spine of the bicycle. If your chain becomes slack or breaks, the wheels will cease to function. But even though chain problems are a fairly frequent occurrence on most BMX bikes, there are quick ways to fix the problem.

Instructions

    • 1

      Place your bike upside down and stand it up on its handlebars so you can access the chain and sprockets easier.

    • 2

      Pull the chain completely off the sprockets and straighten it out.

    • 3

      Inspect the chain to see if it is broken. If it is, you will have to buy a new one. If it has simply slipped off the bike, proceed to the next step.

    • 4

      Identify whether you have a traditional chain or a two-sided chain. On a traditional chain, you can attach either side to the sprockets; on a two-sided chain, you can attach only the side with the grooves.

    • 5

      Fit the chain over the end of the sprockets and fit a few individual links into the individual sprockets. This will guide you for attaching the rest of the chain.

    • 6

      Place the remainder of the chain over the sprockets and ensure that all links in the chain are fit onto the sprockets.

    • 7

      Rotate the wheels to set the chain.
