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.

An arm powered cycle has an arm drive with a hand bar. Oscillating fore and aft movement of the hand bar is converted to rotational movement to drive a driven wheel by a dual, reverse motion slip clutch. The hand bar can have a U-shaped yoke with a seat positioned between uprights of the yoke. The yoke can be combined with an integrated steering mechanism to both drive the driven wheel and turn a directional wheel. A combiner can combine motion from the arm drive and a leg drive.

Embodiments of the present disclosure include an apparatus powered by arms and legs with the legs transmitting power through foot pedals coupled to pedal arms that are coupled to a shaft offset of the pedal sprocket center shaft. Arms transmit power through a lever arm system with pivot points coupled to the frame to isolate arm power motion from front fork steering motion. Steering levers mounted on arm cranks control motion to the steering column and front wheel forks through a cable.

A rider-propelled vehicle comprising a rear wheel assembly, a front wheel assembly, a dual drive and steering assembly, and a drive train. The rear wheel assembly and the front wheel assembly include 24 inch (ISO 507 mm) or larger wheels. Pedals of the dual drive and steering assembly extend laterally exterior from drive links of the dual drive and steering assembly so that feet of the rider straddle the left and right drive link. A steering train of the dual drive and steering assembly is configured so that the front wheel assembly turns entirely forward of the range of motion of left and right handlebar assemblies of the dual drive and steering assembly.
