How do I fix a flat tire on my bike?

Flat tires are an inevitable part of cycling. Knowing how to fix a flat tire on a bicycle is an essential skill for any rider. Whether you're a beginner or a seasoned cyclist, being prepared to handle a flat tire can save you time and frustration on your rides.

What tools do you need to fix a flat tire?

Before hitting the road, make sure you have the necessary tools to fix a flat tire. You will need a spare inner tube, tire levers, a hand pump or CO2 inflator, and a multitool with a wrench to remove the wheel.

How to remove the wheel from the bike?

Start by shifting the chain onto the smallest cog to make it easier to remove the wheel. If you have rim brakes, release the brake calipers. For bikes with disc brakes, you can remove the wheel without adjusting the brakes. Use your multitool to loosen the axle nuts or quick-release skewer and carefully remove the wheel from the frame.

How to locate the puncture and remove the inner tube?

Inspect the tire for any sharp objects that may have caused the flat tire. Once you locate the puncture, use the tire levers to carefully remove the tire from the rim. Take out the inner tube and check for the puncture by inflating it slightly and listening for the hissing sound of air escaping.

How to patch or replace the inner tube?

If you have a patch kit, locate the puncture on the inner tube and roughen the area with sandpaper. Apply the patch and wait for it to dry before reinserting the inner tube into the tire. If the puncture is too large or the tube is damaged, replace it with the spare inner tube.

How to reassemble the tire and wheel?

Once the inner tube is patched or replaced, carefully insert it back into the tire and make sure it is evenly seated inside the tire. Starting at the valve, carefully work the tire back onto the rim using your hands. Avoid using the tire levers to prevent pinching the tube.
