A front wheel drive recumbent bicycle frame and bicycle are described wherein the wheelbase is adjustable between a fully extended position and a fully retracted position by adjusting the length of a telescoping main tube. The main tube of the bicycle frame rises as it extends rearwardly relative to both a flat underlying surface and a line drawn from the front dropouts to rear dropouts. Accordingly, the adjustment of the wheelbase also changes several important bicycle parameters including the head tube angle, trail, and backrest angle.
