Abstract
A recumbent vehicle comprising a single, bowed tubular member forming a main frame having a front end and a rear end. A rear wheel fork assembly is mounted toward the rear end of the main frame with a rear wheel rotatably mounted in the rear wheel fork assembly. A crank assembly, including crank pedals, is mounted to the front end of the main frame. The crank assembly is adjustable to alter the distance of the crank pedals from the front end. A pair of front steering wheels is rotatably mounted toward the front end of the main frame, rearwardly of the crank assembly. A body seat, substantially conforming, throughout its length, to the bowed shape of a portion of the main frame generally intermediate the front steering wheels and the rear wheel, is mounted in alignment with said portion of the main frame.
