ABSTRACT:
The invention provides a light weight bicycle or tricycle of low wind resistance and low center of gravity principally composed of two frames over-lapping in tandem and joined by a journaled bearing. The front part of the front frame carries a bracket for the front wheel; the rear part of this frame is first depressed and then bent upwardly to provide a seat for the rider and a back rest. The rear frame largely extends under the rear part of the front frame and carries a rear bracket (or brackets) for the rear wheel (or wheels). The front of this frame is bent substantially vertically upwardly and is joined to the first frame by a bearing which engages an upwardly rearwardly slanted journal located at about the midpoint of the front frame. The vehicle is steered by a handlebar which turns the first frame relative to the second. The vehicle is propelled by conventional pedal or motor drive on the front wheel.
