摘要:
Embodiments of the present invention comprise a lightweight front wheel drive recumbent road bicycle and an associated frame. A front triangle is provided to which the drive train of a standard road group can be attached and utilized. A telescoping tube assembly is provided in the front triangle to permit the distance of a bottom bracket and crankset from a seat pan to be adjusted for riders of different sizes. The handlebar is coupled to an end of the telescoping tube assembly and no traditional handlebar stem attached to a steering tube is utilized, so that the structure provides maximum stiffness to better capture the input of the arms and upper body when maximum power is required. The seat pan and a seat back are integrated with the main frame truss structure to help ensure the maximum transfer of the rider's energy to the drive train.
