How do bicycles work?

The bicycle works by rolling on two wheels, of course. It has a pedal and it has a chain. You get on the bicycle on the seat and you pedal away. You steer with the handlebar. That is a bicycle. It has air on those tires. You can pedal fast or slow, and that's the speed that you'll get.
