A fixed-gear bicycle is a bicycle that has no freewheel, meaning it cannot coast — the pedals are always in motion when the bicycle is moving. The sprocket is screwed directly onto the hub. When the rear wheel turns, the pedals turn in the same direction. This allows a cyclist to stop without using a brake, by resisting the rotation of the cranks, and also to ride in reverse.
