Abstract
A dual powered propulsion system for use with a human powered vehicle is provided. The system includes a connecting rod with a front end operatively coupled to yoke-connected forearm bars. The system also includes a splitter coupled to a rear end of the connecting rod, wherein the splitter is coupled to a first rack and a second rack that operate with a first and second pinion gear to turn a crank axle. This system supplies rotational power to the crank axle in a single rotational direction as the connecting rod is oscillated up and down and back and forth. Even though a solid connecting rod is used to transfer power from the oscillating forearm bars to the crank axle, the vehicle is steerable to the right or left as a result of the use of a carriage, on rollers, and a turning track operatively connected to the forearm bars.
