ABSTRACT:
A recumbent bicycle has a tubular frame member with a longitudinal axis running from front to rear. A rear support module includes a saddle for nestingly embracing a rear portion of the frame member. Cantilever support members extend downward from the saddle to free ends which are attached to an axle for a rear wheel. A head tube and bearing attached to the front of the frame member support a head shaft and a fork with a bifurcated lower portion suitable for mounting a front wheel. The fork lies generally in a plane and is supported, set forward of the head shaft, by extension plates such that the head shaft axis intercepts the fork plane. A drive sprocket assembly is at the front of the frame member. A seat assembly has opposing track slides engaging a track at the top of the frame member. The slides can be drawn together to clamp the track and fix the seat. The fork and rear support member are of such relative lengths that the front of the frame member is closer to a supporting surface than the rear of the member and, when the seat is moved along the track toward the sprocket assembly, it also moves toward the steering stem and the supporting surface.
