<human>:  How do I fix a flat tire on my bike?
<bot>: To fix a flat tire on your bike, you will need to remove the wheel, then use a tire lever to remove the tire from the rim. Once the tire is off, remove the inner tube and patch up any holes or punctures. Finally, re-inflate the tire with a pump or an air compressor and re-attach the tire onto the rim and the wheel to the bike frame.
