A rack driven human powered vehicle utilizes a rack and pinion system to provide a more efficient method of propulsion. The rack and pinion system may take the linear momentum of at least one driving rack and may transfer it to rotational momentum for at least one freewheel sprocket which may turn the wheel providing momentum for the vehicle.

A harmonic ring gear system can include at least one inner gear with external toothing, the at least one inner gear defining an axis of rotation; at least one outer gear with internal toothing arranged concentrically to the at least one inner gear about the axis of rotation, the internal toothing spaced apart from the external toothing; a pin ring positioned between the at least one inner gear and the at least one outer gear, the pin ring comprising a multiplicity of pins; and a rotary transmitter configured to lift a portion of the pins of the multiplicity of pins off the external toothing and press the portion of the pins into the internal toothing.

A harmonic pin ring gear system includes an input and output shaft and two outer gears, each with internal toothing, a single inner gear with external toothing arranged concentrically to a first outer gear and inside said first outer gear in axial direction, and a drive means extending between the two outer gears and the inner gear comprising a pin ring formed as one part in circumferential direction and a multiplicity of pins that protrude laterally in axial direction from the pin ring, a rotary transmitter for lifting the drive means off the external toothing of the inner gear and pressing the drive means into the internal toothing of the outer gear, wherein the input shaft is mounted on one side in the inner gear, the inner gear is mounted in an inner gear ball bearing, and the inner gear ball bearing is mounted in a housing cover.

Vehicle includes a frame, a seat arranged on the frame, a wheel rotatably mounted on the frame, an elongate directional slider, a pedal on the directional slider that slides between first and second positions, a main drive chain connected to the first wheel, a main drive sprocket that rotates the main drive chain and thus the first wheel, a flywheel that rotates the main drive sprocket, and an energy generating system that converts sliding of the pedal on the directional slider into rotational force to rotate the flywheel. The energy generating system may include a first electrical coil assembly connected to the pedal, a second electrical coil assembly in connection with the directional slider and that cooperates with the first electrical coil assembly to cause generation of electricity, and an electrical motor that is powered by the generated electricity and is coupled to the flywheel to rotate the flywheel.

The function of this invention is to provide exercisers with a safe and easy way to convert a legs-only exercising device, such as a stationary trainer or bicycle, with the capacity to exercise their upper and lower body muscle groups simultaneously or separately. This invention is portable and can be moved easily from one legs-only exercising device to another. Once they are mounted onto the handlebar or attachment bar of the legs-only device, it is now a full-body trainer. Exercisers mount the trainer, place their feet on the cycling pedals, place their elbows onto the elbow holders, grasp the hand grips, and now start their full body exercising activity. The degree of difficulty of their exercise trek is easily accommodated by allowing the rider to adjust the resistance for moving the forearm bars up and down for an upright bike, or back and forth for a recumbent trainer.

Tri-Power Exercising device allows a rider to simultaneously, or on demand, exercise virtually all muscle groups in his lower and upper body. The device includes a bicycle frame, pedals, forearm bars, sliding seat, computer and electronic display recommending energy modulation amounts from various muscle groups to optimize physical performance on any given trek. Because riders can exercise virtually all muscle groups at once, they reduce their exercising time, continuously builds muscle tissue throughout their whole body, and exercises their cardiovascular and respiratory systems completely. Riders operate the device by rotating legs on the pedals, rotationally oscillating the forearm bars up and down with their arms and shoulders, and then use core muscles to pull and push the seat back and forth on the slider. Inverted racks, pinion gears, and one-way bearings turn this linear power from the oscillating forearm bars and sliding seat into torque that rotates the crank axle.
