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.

The present invention relates to a rider's simultaneous use of his forearms/hands and legs to provide dual power into a propulsion system for riding a cycle vehicle, including a bicycle and a tricycle, or other vehicles. The invention permits the rider to have complete control turning the cycle vehicle, at will, right or left, while at the same time pumping a set of forearm/hand bars in an up power stroke and a down power stroke. In addition, even though the pumping action is lineally moving a telescoping rod and a push/pull cable back and forth, it is also simultaneously rotating a flywheel, upper and lower sprockets, and the crank axle to drive the bicycle wheel forward over the riding surface. Thus, the rider can provide maximum power into rotating the rear tire by simultaneously using both his arms and legs, while contemporaneously controlling his direction of travel.

A collapsible tricycle having linkage to all three wheels enabling a smaller turning radius when all three wheels are tilted during a turn. The tricycle folds through the rear frame having a hinged rear axle with linkage to pivotal handle bars mounted to the rear frame that when pivoted from their storage position to their operative position also pivots the rear axle through said linkage from its stored position under the rear frame into its operative position. The rear axle is segmented so that when moved to its stored position under the rear frame each of the rear wheels can be pivotally collapsed against the frame.

The gear driven by wobble movement contains an ergonomic pendulum (D), a centric disk (C) and a flywheel (A) which have a common axis (S) of rotation. In the axis (S) of rotation a shaft (H) is placed which is rigidly joined to the pendulum (D). The mutual concentric position of the centric disk (C) and the flywheel (A) is delimitated by one planet disk (B) at least which contacts the outer periphery of the centric disk (C) and the internal periphery of the flywheel (A) and is joined rotatably to the supporting structure (T). The supporting structure (T) is fixed to the linked structure which fixes the supporting structure (T), together with the planet disk (B), against rotation with respect to the axis (S) of rotation. Between the shaft (H) and the flywheel (A) a first freewheel (VI) is situated while between the shaft (H) and the centric disk (C) a second freewheel (V2) is situated. The senses of rotation of the freewheels (VI and V2) are different. The vehicle comprising this gear has a linked structure to which the supporting structure (T) is fastened, having the form of the frame (U). To it the wheel (K) or the pair of wheels (K) are fastened.
