Purple fixie

 

In Australia, "fixed-wheel" is the normal term for the subject of this article — meaning the opposite of freewheel, and "fixed-gear" usually refers to a single-speed bicycle.

A fixed-gear bicycle (or fixed-wheel bicycle, sometimes known as a fixie) is a bicycle that has no freewheel, meaning it cannot coast, as the pedals are always in motion when the bicycle is moving.
