A single speed bike does exactly what it says on the can: it's a bike with just one gear. It still has a front and a back brake like any other bike but just fewer gears. And by fewer we mean just one solitary gear.

Riding at its most simplified form is riding a bike with just one gear. That's what the first Tour de France riders did in 1903 and what people still do today whether they are riding to work on a single speed bike or blitzing round a velodrome on a fixed gear bike.
