One of the most important steps before reinstalling the repaired tube is carefully checking the inside of the tire for whatever cause the puncture. On a road bike this is often a piece of wire form a blown out car or truck tire - highway shoulders are littered with this stuff. Run your finger cautiously around the inside of the tire and you will often encounter the culprit still sticking through the tread. If you do not remove this, you will be fixing another flat almost immediately. I found this out the stupid way!

Something my dad never showed me how to do, I just went to him with a flat tyre and as if by magic half an hour later I was off again. Really useful, thanks for the invaluable info and easy to follow instruction.

When he said that snake bite punctures were common on mountain bikes I thought for a second that snakes biting people's bicycle tires was a common occurrence lmao

Great video, clear & precise. One addition though, to get the plastic off, fold the patch in half once it's stuck, this makes the plastic split so you can peel it from the centre of the patch rather than the sides. This will stop it wanting to peel at the edges.

A good tip on quickly looking for the cause of the puncture: Before removing the tire, use your marker to mark the spot where the valve was located. After you repair the puncture, put the inner tube on top of the tire, aligning the valve with the mark. You can then inspect the part that’s aligned with the patch. That being said, it’s also a good idea to regularly inspect the entire tire in order to preemptively remove any possible causes of future punctures. But this tip will be useful if you’ve just made an emergency roadside/trailside repair and are eager to move on already. You can do the more thorough inspection once you’re safely back home.

These videos are so useful. With so many folks getting bikes during the pandemic, they're such great resources for those just joining the community!

I am about to put on a patch over the same hole for the 3rd time. Repair kit instruction was misleading and ended up wasting 2 patches before coming to this video. Now confident about how to do it and hopefully will succeed. Thanks for the explanation!

Thank you for putting the video up. A note for everyone using the repair patches, the plastic film can be removed from the center outward by breaking the dotted split with one's nails, or tweezers :).

Clear and precise, only been riding a few weeks and despite Schwalbe puncture resistant tyres had my first flat today . Useful video. When you don’t know, you don’t know !

I always recommend that the time while the glue is drying is most usefully spent finding the cause of the puncture, cos if you forget this step, then you'll have completely wasted your a cup of tea indeed..

Three useful tips. (1) I mark the position of the hole by putting a pair of wooden sprung clothes pegs about an inch either side of it. I then know that the hole is half way between them. I have put a mark on each clothes peg and if they are lined up, even a tiny and invisible hole can be accurately marked without having to try to find a pen that draws on the tube. (2) Always check for OTHER punctures before replacing the tube. If you rode through thorns or glass, there may be two or more. (3) Always thoroughly check the tyre inside in case the tip of the thorn is still there, otherwise it will make another puncture as soon as you pump the tube up again.

I always run out of patches before I empty the tube of glue and started cutting up old innertubes and using a piece of one as a patch. Clean and sand the tube and your piece of tube patch, apply a bit of glue to both, let it dry until it's tacky, apply, reassemble the wheel and inflate to full pressure.

The Park Tool Vulcanizing Patch kit is the best in the world and super cheap also, picked mine up at local bike shop for just $2.00 and within a few minutes after locating the hole, the wheel was back on and I was riding again. Excellent value and they stay on forever and actually become part of the rubber.
