Step 1: Remove the Wheel
It’s much easier to fix a flat if you first remove the wheel from your bike. Removing the wheel is a 2-step process:
First, Release Your Brakes
Most brake assemblies sit very close to your wheel rims and use a quick-release system to disconnect and reconnect them. The exact location and design of these release systems will depend on your style of brakes.
- Some have a knob at the end of the pull-cable that catches on a notch in the caliper arm. Squeeze the brake arms together to release the cable.
- Others have a quick-release lever, just like on your axle, which can be opened to release the brakes.
- If your bike has disc brakes—most mountain bikes have these—be careful not to touch the rotor when opening the quick-release mechanism. The rotor is located very close to the quick-release lever and can become hot enough to burn you.
