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 scooter, including a main body, a front wheel, a first rear wheel, a second rear wheel, a drive part and a controller. The front wheel is rotatably arranged at a front part of the main body. The first rear wheel and the second rear wheel are spaced apart and rotatably arranged at a rear part of the main body. One drive part is provided, which is connected to the first rear wheel, and is configured to merely drive the first rear wheel to rotate, so as to driving the main body to move. The controller is electrically connected to the drive part to adjust a rotation speed of the drive part, so as to adjust a rotation speed of the first rear wheel.

Disclosed is a draw-bar box-type quickly folding micro electric vehicle, comprising of a seat frame assembly (1) that is horizontally arranged, the top surface of which is provided with a foldable backrest. A pair of symmetrically arranged rear wheel assemblies (2) are arranged at a position, close to a rear of the vehicle, on the bottom surface of the seat frame assembly (1), and two vertically downward first connecting posts (101), which are provided near the front of the lower end of the seat frame assembly (1). A footrest assembly (4) is hinged to the lower ends of the two first connecting posts (101) through the first connecting assemblies (3). The footrest assembly (4) is arranged parallel to the seat frame assembly (1), and the plane of the footrest assembly (4) is lower than the plane of the seat frame assembly (1). A steering column assembly (5) is hinged at the end of the footrest assembly (4) away from the seat frame assembly (1), and a front wheel assembly (6), with a power device, is attached at the lower end of the steering column assembly (5). A very low footrest assembly (4) is hinged to the seta frame assembly (1) by means of the first connecting assembly (3), so that the user does not need to raise their legs to use the vehicle. Thus, use of the vehicle is convenient and safety risks are reduced.
