<human>:  How do I repair a flat bicycle tire?
<bot>: The first step in repairing a flat bicycle tire is to remove the wheel from the bike frame. You should then use a tire lever to pry the tire off the wheel rim. Once the tire is off, use a hand pump to inflate the new inner tube, making sure that there are no punctures. Next, fit the inner tube back into the tire and place the tire back onto the rim. Finally, use the hand pump to fully inflate the tire for a secure fit.
