A recumbent bicycle including a frame having a longitudinal main tube divided into a main tube front section telescopically inserted into a main tube rear section to form an adjustable length frame. A forked yoke is pivotally fixed to the main tube front section. A front wheel is rotatably mounted on the yoke. A rear wheel is rotatably fixed to the main frame adjacent the frame rear end. A pedal assembly of a driving mechanism for driving the rear wheel is mounted on the main tube front section adjacent the frame front end. A seat and a handle assembly are mounted on the main tube rear section adjacent the frame rear end. A linkage rod operatively connects the handle assembly and the front wheel yoke. The linkage rod is preferably slidably mounted on a central member of the handle assembly allowing a user to modify the steering ratio between the rotation of the handlebar assembly and the corresponding rotation of the front wheel yoke. The seat is provided with inflatable air bags that modify the contour and consistency of various seat sections. A pair of crash bars extends laterally from the frame adjacent the handlebars preventing the handlebars from coming into contact with the ground surface upon a sideward tilt of the bicycle. The driving mechanism includes a pair of chain and sprocket assemblies which are connected in series through a common intermediate sprocket axis. A windshield is mounted adjacent the frame front end.
