Sooner or later, you'll ride over some glass or perhaps hit a rut or hole and get a flat tire. When this happens, don't panic! As long as you carry a few basic tools (photo), flat repair is easy -- even fun! Here's how it's done:
You'll need (l to r): a pump (carried on your bike or in a
pack),
a spare tube (to replace the popped one) and tire levers (for removing the
tire).
Step 1: Open the brake
Step 2: Remove the wheel
Step 3: Remove the tire & tube
Step 4: Inspect the tire
Step 5: Install the tube & tire
Step 6: Inflate & seat the tire
