How to repair a bike puncture

A puncture can happen to anyone, but with a bit of know-how you can be rolling again in no time. Here’s a step-by-step guide:

1. Remove the wheel

• Rear wheel: Shift into the smallest cog (hardest gear) to make it easier.

• Quick-release: Open the lever; release rim brakes if fitted.

• Thru-axle/bolted wheels: Use the correct hex key or spanner.

• Tip: When removing the rear wheel, pull the derailleur back to ease the wheel out.

2. Deflate the tyre fully

• Schrader valve: Press the pin inside.

• Presta valve: Unscrew the locknut and press down.

• Remove dust caps if fitted.

3. Unseat one side of the tyre

• Start opposite the valve.

• Use a tyre lever to lift the bead and hook it onto a spoke.

• Work around with a second lever until one side is off the rim.

4. Remove the tube and check for damage

• Take out the inner tube.

• Inflate slightly to find the hole (look, listen, or feel for escaping air).

• Check the tyre carefully for sharp objects still inside.

5. Repair or replace the tube

• Patch repair: Lightly sand the area, apply glue (or use a self-adhesive patch), press firmly, and let it set.

• Replacement: Fit a new tube and repair the old one later if you like.

6. Refit the tube

• Insert the valve into the rim hole. Secure with the locknut finger-tight (if Presta).

• Tuck the tube into the tyre, adding a little air to help it hold shape.

7. Reseat the tyre

• Starting at the valve, push the tyre bead back into the rim with your thumbs.

• Check the tube isn’t pinched between rim and tyre.

• Use tyre levers gently if needed.

8. Inflate and refit

• Inflate gradually, checking the tyre is seated evenly.

• Pump to the recommended PSI (printed on the tyre sidewall).

• Refit the wheel, tighten the quick release/axle, and reconnect brakes if needed.

• Spin the wheel to check everything’s aligned.

And that’s it — puncture fixed. With a little practice, this becomes a quick and confidence-boosting skill that keeps your rides rolling.
