How To Repair a Bicycle Puncture

from the website

Firstly, make sure that it’s not your valve that’s leaking. The best way to test this is to immerse the valve in water. If you can see bubbles, that’s the problem.

Repairing a puncture is easier at home than on the road, and you’ll need the following tools and materials – tyre levers, a spanner, a puncture repair kit, a bike pump, a spare inner tube, and a bucket or bowl full of water.

Locate the puncture by rotating the wheel and checking for sharp objects, which must be removed. To repair the puncture, first remove the wheel by loosening the wheel nuts with a spanner, and if you have a modern bike, operate the quick release bolts or mechanisms on your brakes. Take the wheel off.

Check that the inner tube is deflated, push the side wall of the tyre away from the rim – this must be done on the opposite side to the value. Insert the flat end of a tyre lever into the gap, and push the lever down to hook over a spoke. Insert a second tyre lever next to the first and repeat the process. Place a third lever carefully under the tyre wall, and run it all the way round the tyre wall. One side of the tyre is now free, so you can reach in and pull out the inner tube a section at a time. Unscrew the valve and push it out carefully.

Give the inner tube two or three bursts of air with your bike pump. Place the tube in a bucket or bowl of water, and look for bubbles. Mark your puncture with a crayon. Take the sandpaper from the puncture repair kit, and roughen the surface of the inner tube. Apply the rubber solution and blow on it to speed up the drying process. Then chalk over the rubber solution to soak up any water, and place the patch over the rubber solution.

Check the inside of the tyre to see that it is clean and anything that may have caused the puncture is removed.

Carefully putting the valve back first, replace the inner tube. Pump it up gently and tuck it up against the rim all the way round the wheel.

Push the tyre wall up and back over the rim, starting at the valve. Check the valve is in the correct position, at right angles to the rim.

Pump up the tyre, re-connect the wheel, then the brakes, and check to see if your brakes are functioning properly. Your tyre should be firm, and you’re now ready for that bike ride.

  1. I am amazed that nothing has changed in the last 50 years. This is exactly how I did it when I was a child! I just checked to see if any technological advances had been made (self-repairing inner tubes, perhaps?) as I am preparing for a cycling adventure after a very long absence.

  2. Thanks for that!

  3. Good Video

  4. This is a splendid video – informative and to the point. Thank you.

  5. One important thing this video doesn't mention is that you're supposed to allow the solution to dry before you apply the patch.

  6. Could u make a video on that within 20min. I need to fix mine asap lol. Thanx!

  7. thank you

  8. i can fix a tube without a puncture repair kit!

  9. yes but you need to cover it in adhesive glue!

  10. his innertube must have "Blew Up"

  11. Does duck tape work???

  12. Dude wtf are you doing here xD 

  13. I always thought the white crayon wasn't worth anything.

  14. in case you got a puncture out on the road and wanted to fix the tube back at home, so the spare is just a placeholder

  15. He finishes by cycling off on the wrong side of the road…..

  16. HAHA!
    YOU obviously don't… Maybe a previous head injury from not wearing a helmet has caused you to forget how to spell 'douche'? 

  17. I thought the video was as old as the hills, and then I notice it was made in 2007?! It's almost like a parody!

    Still, was very useful.

  18. uhhhhhh this is so hard! :'( thanks though.

  19. He said you need a spare (in case their is a hole) inner tube "0:35"

  20. so how much rubber solution do I need to use? enough to cover the area the patch takes up?

  21. did i just see some bloody green socks?

  22. *sigh* common issue

  23. That's because it's a lost head nail. The head is small so it can be hammered into the surface of wood for aesthetic reasons (i.e. no flat head visible on the surface of wood). It's not the point you're seeing sticking out here.

  24. I took the wheel off,took the inner tube out,found the hole,marked it with crayon.And what a surprise,NO GLUE!!! plenty of patches and sand paper but no glue.

  25. This is a very good vid/

  26. The one bit I wanted to see – peeling off the patch – not shown!

  27. looooooooooooool

  28. just in case ur inner tube is unfixable lol 

  29. which way does the patch go round?

  30. He's English but riding on the right-side of the road ? Whats going on ?!

  31. Hot or cold water?

  32. Nice granny gear as you ride off mate

  33. very useful… thanx….. 

  34. I purchased 2 silverfox moutain bike's from argos and in the first few days kept getting very slow punctures that slow that could not find puncture, replaced inner tube's and happened again so stripped down wheel for inspection and noticed that the inside rim had some rough edges were it had not been machined very well so i sanded them smooth with sanding paper and now it seems ok…..

  35. Both my tyres got punctured 🙁
    I have my puncture repair kit to sort it out, it's one of those damn parks that had thorns in real hard-to-see places, when there's usually nothing there.

  36. @ankofon oh god ur so unequivocally rite this vid so ztupid!!

  37. try to find the puncture by holding the inner tyre up to your ear and listening for a hiss before using the bowl of water method. The inner tyre at the point of the puncture has to be completely dry for the rubber solution to take, so if you can find the puncture without getting the inner tyre wet you'll save yourself some time
