An independent shaft driven front wheel drive transmission (20) powers the front wheel of a velocipede by rotating a pair of coextensive handles (23 L R). Standard foot pedals power a rear shaft drive assembly (17) or a standard chain drive (FIG. 9). Forward rotation of the handles sets in motion the shaft driver assembly (10). The drive shaft (35) rotates and transfers energy to the multi-geared front hub assembly (14) that drives the front wheel forward. Triple tree brackets (73), position and support the front forks and steer tube. The steer tube (24) in combination with the triple tree brackets attaches the front wheel shaft drive system to the head tube of the velocipede. The modified front fork tube (53 R) houses the drive shaft (35) and bearings, (56 a b). The fork tube also has an attached modified drop out (77) that has clearance for rotatable bottom gear (51).
