Balancing at a road junction. Fixed wheel bicycles also known as fixies are a common site especially in East London, where they have become incredibly fashionable. The simple single gear system is complimented by colour combinations of the frame and wheels, often in flourescent colours. A fixed-gear bicycle has no freewheel, meaning it cannot coast — the pedals are always in motion when the bicycle is moving. The sprocket is screwed or bolted directly onto a fixed 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.
