Abstract
Disclosed is a recumbent bicycle having a frame with at least one tubular member having a lumen. Mounted to the frame are a rear wheel assembly and a transmission assembly. The transmission assembly can include a first gear, a second gear, and a chain that extends from the first gear to the second gear and through the lumen of the at least one tubular member. Pedals and crank arms can mount to the second gear, which is slidable relative to the first gear to vary the position of the second gear relative to a seat mounted to the frame. A suspension assembly can mount a pair of front wheels to the frame at a location intermediate of the first portion and the second portion of the frame. The bicycle enables riders of different leg lengths to use the recumbent bicycle, while the suspension assembly cushions the rider during use.
