Racing with high wheel bicycles was the formula one of its time. The track were generally made of ash and measured ¼ mile (400m) or sometimes less. Spectators either stood outside the track or, at larger grounds, could sit in the stands.

Manufacturers produced special racing models half the weight of a normal one.
