Fixing a flat tire, repairing or replacing a broken chain, or even replacing a spoke are not hard to do and require just a few basic tools. Take this quiz to learn more about repairing your bicycle.
What should you do when you can't remove a flat tire by hand?
Use bike tire irons.
If you can't remove a tire from the rim by hand, use bike tire irons. Starting at a spoke, insert the plain end of a tire iron carefully between the rim and the tire; pull the slotted end down and behind the spoke, and hook the slot over the spoke to hold the tire iron firmly in place. Insert a second tire iron at the next spoke and repeat to pry more of the tire until the you get the tire off.
What is the easiest way to check a tire tube for leaks?
Scan over the tube surface manually.
Put an air-filled tube into a bucket of water.
Use a bicycle pump to fill the tube until it's firm. Fill a bucket with water, then hold the tube underwater a section at a time and watch for air bubbles. Check the entire tube; there may be more than one leak. Mark any leaks with chalk.
What is the most common method of measuring chain length?
Measuring the distance between the rear sprocket and the front chainwheel.
If you can't measure by the old chain, check chain length by stretching the chain into place around the rear sprocket and the front chainwheel, exactly as the old chain was installed, with the two ends meeting at the front chainwheel.
Inadequate braking is often the result of a loose brake cable on one or both bike wheels. It can also be caused by wear to the brake shoes, the blocks of rubber that press against the wheel rims when the brake levers are squeezed.
