The present invention provides a propulsion apparatus for human powered vehicles and machines. The propulsion apparatus is powered by exerting a force (such as the operator's weight) onto the foot pedals in a reciprocating fashion. It is comprised of two ratcheting arm foot pedals which transfer a high torque and low speed input to the output axle ; transmission elements for shifting the displacement of one arm foot pedal into an equal and opposite displacement of the other one; and an arrangement of gears and ratcheting crank arms which convert the alternating motion into rotational motion and transfers a low torque and high speed input to the output axle. The high torque low speed input engages when the output axle slows down to a certain speed and the low torque high speed input is engaged until the output axle reaches a certain speed in order to achieve and maintain an overall good average torque and speed in the output axle.
