One of the nice parts about working in an office with others who active commute is the brain trust that naturally forms around simple, yet intimidating topics, like how to change a flat bike tire.
The conversation first started among a few of us saying how we felt silly that even though we promote biking and bike to work most days—we don’t actually know how to change a flat. Just a few short weeks after this conversation took place, we were all down in the garage huddled around our bikes learning how to change a flat.
There are a lot of great resources out there that have already outlined the best ways to fix a flat, so instead of reinventing the wheel, we’ve included two pieces below from The Bike House that we actually used during our bike maintenance workshop.
To fix a flat, you need some basic tools—a patch kit, tire levers, and a pump (and a crescent wrench if you don't have quick-release wheels).
The easiest way to work on your bike is by flipping it over and setting the bike on the seat and handlebars. Loosen the axle bolts or quick release lever until the wheel is free. To get the wheel off easily, you often need to disconnect your brakes or undo a quick-release lever on your brakes.
Empty any remaining air by pressing on the air valve. You need to get one side of the tire bead out by prying it open with plastic tire levers (not metal, so you don’t further damage the tube). It usually helps to get two in side-by-side, then slide one around to get the tire halfway off, but sometimes three are necessary. With half of the tire still on the wheel, you can pull the tube out; be careful of the valve area.
You need to find the hole (or holes) to determine what caused your flat. Pump some air into the tube and slowly look over the tube, listening for the hiss of air or trying to feel where the air is blowing out with your cheek. You also need to (carefully) feel the inside of the tire to make sure whatever punctured the tube in the first place isn’t still there.
Once you find the leak, follow the instructions included in your patch kit.
If you pinch the tube while forcing the tire back on, you might be back to square one. You can usually get the tire back on gently without using tire levers.
Pump your tire carefully, checking as you go for any lumps or abnormalities. Inflate it to the PSI recommended on the side of your tire, which helps prevent future flats.
But if you’re more of a visual learner—here’s the same information in graphic form with a cute illustrated pup.
There was a lot of great conversation happening during the workshop and some of the best tips I picked up were:
