ABSTRACT:
A bicycle comprises a frame made of a plastic material or aluminium, which frame comprises a structural center section and two bracing members located externally relative to a vertical plane each defined by the laterally outermost point of each foot pedal. The frame is in form of a hollow case and comprises a forward closed hollow case member, in which a handlebar stem tube and a foot pedal bearing device are molded and comprises further a rear support structure, in which the rear wheel of the bicycle and a saddle support are mounted. A fairing is provided as integral part of this frame structure increasing the aerodynamic features thereof. The structure of the frame allows together with this fairing to provide a lightweight, twisting resistant structure resistant to bending, too, which is integrable into the fairing.
