Abstract:
A slow speed, driver's stand-up only, three-wheels, portable, leverless, extremely lightweight, two-part personal mobility vehicle. A front major part, wheel drive assembly, comprising of an upper sub-part, comprising of levers free steering handle mounted on steering column. A lower sub-part comprises of an extended backwards supporting leg, a control box, an electric chain motor assembly, a fork assembly, and front wheel assembly. A two-part hinge assembly below the steering column, enabling folding steering column, and, if necessary, removal. A second major part, a rear assembly chassis, comprising of a riders flat platform surface mounted on a rectangular metal frame, partially mounted on a rear axle, which is connected to both rear wheels. A rear hydraulic foot brake system installed in both rear wheels, whereby a foot brake (pedal) lever formed on top platform surface. An alternative, none-emergency hand brake lever, may be fastened on the steering handle. A removable battery pack is formed on the platform surface. A two-part telescopic box fit assembly, whereby a receiving part is mounted upward on the end of extended leg; a second, sleeve-type part, is formed, respectively, downward on the front platform frame, for interconnecting both major vehicle parts into a complete vehicle, ready to drive at lower speed than 5 MPH. Two sets of simple outlet-plug assembly are formed on respective parts of the battery and platform, and on both ends of the telescopic assembly to supply power to the motor. Said telescopic connecting mechanism enables assembly, disassembly, loading and unloading in less than seven seconds.
