How to Repair a Bike Puncture
No matter how often or how little you ride your bike, a puncture is pretty much guaranteed. Thankfully, they're really easy to repair and with this guide we'll get you back on the saddle in no time!
What Do I Need?
Part 1 - Taking Out The Inner Tube
- Take a look at your tyre and remove anything that may have caused the puncture, like a thorn or a nail.
- Loosen the wheel nuts with a spanner (or undo the quick release bolts if your bike has those instead). Check that the inner tube is deflated.
- Grab the wheel on the opposite side to the valve. Insert the flat end of a tyre lever into the gap, then hook the other end onto a spoke.
- Move the tyre around about 4-5 inches and do the same again with a second lever, working your way round the whole tyre using two or three levers.
- Remove the inner tube. When it's out, check the inside of the tyre to make sure that whatever caused your puncture is gone.
Part 2 - Repairing The Puncture
- Find where the puncture is, either by listening for air or putting the tube in some water and looking for bubbles. Mark the hole with the crayon.
- Roughen the area around the hole with sandpaper, then stick on the patch from the repair kit. Some patches are pre-glued, whilst others might come with a separate tube of vulcanising solution or rubber cement to stick them on with.
- Put a small amount of air in the tube, put it back into the wheel, then tuck the tyre back over the wheel rim.
- Push the valve back into the hole, seat the tyre and pull the valve back through.
- Pump the tyre back up to the correct pressure and put the wheel back on your bike.
If you get a puncture when you're out riding it's much easier to just replace the inner tube, which is why it's a great idea to carry a spare one when you're out and about.
If you've had a puncture that's damaged your tyre, and you can see the tube poking through, you can use tape, a gel wrapper or something similar as a 'boot' to cover the hole and get you home. This only works for smaller holes in the tread area of the tyre, though, and is only a 'get you home' solution!
