Abstract: An illuminated bicycle having a body frame, a handlebar and wheels formed of hollow tubular members made of plastic material that allows light to be transmitted radially through their side walls. A high intensity lamp is mounted at a predetermined location within one of the hollow tubular members. A bundle of flexible elongated optical fibers have their one end positioned adjacent the high intensity lamp so that light therefrom would be transmitted through the optical fibers. The optical fibers are threaded throughout the hollow tubular members of the bicycle body frame so that when the lamp is illuminated the hollow tubular members will glow and make them highly visible at night. The lamp may be powered by batteries or a small bicycle generator.
