William J. S. Livingstone (Bill) vegevore Bike: (Updated: 05 Nov. 2001). ![]() The idea of a recumbant bike is not new. It is lower to the ground, which is more stable, and has a more comfortable seating arrangement. Contrary to what some may think, the lack of weight on the pedals is a minor disadvantage, one can exert more force by pressing against the back of the seat. The design suggested here has a front-wheel-drive mechanism. In particular, the pedal shaft (green) crosses over thru a cylinder fixed to the frame (red) and turns a sprocket (green) in the usual way. This goes thru a derailer mechanism and power crosses over to the other side where it enters a second derailer mechanism to the gears and the front wheel assembly (blue). There are 2 sets of shift levers (as usual) giving multi-speeds (10-15 depending on gear & sprocket numbers: 4 & 3 for 12 shown on right). The steering mechanism is thru a fixed shaft to the bottom with cables under the seat, passing up the back-side, and out at the top to attach to a steering arm where the handle-bars might be expected at the top of the steered wheel. The rear wheel steering is a distinct disadvantage of this design because it slows the reaction time for avoiding obstacles. |
