A hybrid pump-action vehicle and therapy device may include a pumping arm attached to a lower pump-action assembly. As the pumping arm is actuated, the lower pump-action assembly moves forward and rearward in response to the pumping action and powers movement of the vehicle. The lower pump-action assembly may be releasably connected to the pump arm so that the pump arm can be disengaged from the pumping action but still be usable for steering. A motor may also be provided to provide assistance or full power to the vehicle based on a user-selectable amount of assistance. And finally, the vehicle may be configured such that it can be collapsed to a fraction of its operating footprint to enable easy transport and storage.

A ride-along vehicle may include a spring/chain guard that covers a spring and chain assembly and provides an attachment point for the spring. The guard may have a narrow portion that covers and helps retain the chain on a sprocket as well as a wider portion that covers the spring. In another embodiment, the spring can be connected to a fulcrum that has a chain retention pully, gear, guide, or wheel that keeps the chain tight in loop to improve the pump-action operation of the vehicle. An improved pumper arm and steering mechanism may include a pivot joint that is provided by rods, pins, or bolts attached to opposite sides of the pumper arm. The universal joint between the steering arm and the pumper arm can be aligned with the center of the pivot point to prevent rocking of the steering arm as the pumper arm is actuated.

A scooter (5) includes a head tube (50); a riser tube (51) freely and rotatably pivoted with the head tube (50), the upper end of the riser tube being provided with a handle (511); a preceding runner (52) provided at the lower end of the riser tube (51); a left carrier (53) and a right carrier (53) both connected to the head tube (50); a left back runner (54) and a right back runner (54) provided at the left carrier (53) and the right carrier (53) respectively, which support the scooter (5) alone with the preceding runner (52); the front end of each carrier (53) is provided with a cantilever (533) respectively. The left cantilever (533) and the right cantilever (533) are both provided at the head tube (50) in a suspending form of swinging back and forth freely. Provided between the left cantilever, the right cantilever (533) and the head tube (50) is a holding means (55) enabling the left carrier and the right carrier to perform back and forth alternate swing and displacement action. The scooter (5) is provided with the holding means (55) between the left cantilever, the right cantilever, and the head tube (50). When two feet of the user exert force on the corresponding carrier alternately or two hands exert force on the handle alternately to drive the head tube (50) to swing left and right, by means of the effect of the holding means (55), the left cantilever (533) and the right cantilever (533) will swing back and forth alternately on the head tube (50) and then drives the left carrier (53) and the right carrier (53) to perform alternate back and forth displacement action together, so that the traveling and handling of the scooter (5) is smoother, faster and more labor-saving.

Invention relates to the type of two wheel velocipede where the propulsion to the rear wheel is achieved by the use of riders legs/feet and propulsion to the front wheel is achieved by the use of riders arms and upper body on cranks that travel in circular motion using a single chain as a means to transfer force to the front wheel.

An innovative step is the chest and upper body support pad which enables the rider to relieve strain of the back muscles and provide a surface against which to pull the handlebars

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.
