A three-wheeled self-propelled pedal vehicle with front wheel (116) bicycle steering and independently suspended rear drive wheels (118A, 118B). The three-wheeled self-propelled pedal vehicle may include a tubular frame (102) comprising a bicycle front triangle down and seat tube members connected to a longitudinal symmetrical support frame with upper and lower longitudinal chords where the lower longitudinal chord supports a drive mechanism comprising a tractive element drive from a bicycle crank chain ring to a freehub (804) transfer shaft assembly (600) and a separate tractive element between the freehub (804) transfer shaft assembly (600) and an articulating telescoping drive shaft assembly (200) which drives rear wheel (118A, 118B) axles supported by mirrored independent transverse suspension arms (302A, 302B). |
