Bicycle dual power turning track, rack, pinion, and one-way bearing propulsion system

A dual powered propulsion system for use with a human powered vehicle, the system comprising:

• a crank axle having pedals coupled to the crank axle to supply rotational power to the crank axle by rotational pedaling motion;
• a connecting rod, wherein a front end of the connecting rod is operatively coupled to forearm bars and a rear end of the connecting rod coupled to a splitter, wherein the splitter is coupled to a first rack and a second rack;
• a first pinion gear coupled to the crank axle with a first one-way bearing;
• and
• a second pinion gear coupled to the crank axle with a second one-way bearing, wherein the first pinion gear rotates in a direction opposite the second pinion gear, wherein:
• the first rack is coupled below and engages the first pinion gear and the second rack is coupled above and engages the second pinon gear;
• the first and second racks oscillate back and forth from movement by the connecting rod in response to movement of the forearm bars in an up power stroke and a down power stroke;
• and
• the first pinion gear and the second pinion gear supply rotational power to the crank axle in a single direction in response to the oscillation of the first and second racks and the operation of the respective one-way bearings independent of the rotation power supplied to the crank axle by the pedals.
