Abstract: A foldable personal mobility vehicle is disclosed comprising first and second units having first and second wheels being rotatable about first and second axles. A drive unit rotates the second wheel for moving the foldable personal mobility vehicle. A pivot disposed substantially parallel to the first and second axles pivotably connects the first unit to the second unit for folding the personal mobility vehicle. The foldable personal mobility vehicle may include a folding unit for automatically folding the foldable personal mobility vehicle.

Abstract: A vehicle is disclosed having a reduced turning radius comprising a directional wheel assembly for turning the vehicle and a drive wheel assembly for driving the vehicle. The drive wheel assembly has a first and a second drive wheel independently driven by a first and a second motor through a control circuit. A counter-rotation circuit counter-rotates the first and second drive wheels upon a major turning position of the directional wheel assembly to enhance the turning of the vehicle. A reducing circuit reduces the speed of the motors upon a minor turning position of the directional wheel assembly. The vehicle may include a slide mechanism for providing a reduced wheelbase to further reduce the turning radius of the vehicle. One embodiment of the invention includes an improved steering device for controlling the directional wheel assembly.

Abstract: A central drive personal mobility vehicle is disclosed comprising a frame having a right and a left frame mounting located in a trailing frame portion of the frame with a seat being mounted to an intermediate portion of the frame. A right and a left leaf spring extend between a proximal end and a distal end. The proximal ends of the right and left leaf springs are secured to a right and a left drive wheel assembly supporting a left and a right drive wheel. The distal ends of the right and left leaf springs are secured to the right and left frame mounting for resiliently mounting the right and left drive wheel assemblies to the frame.

Abstract: A personal mobility vehicle comprises front and rear frame sections which can be readily disassembled and assembled and further comprises a drive train unit which can be disassembled and assembled from the rear frame section.

Abstract: A personal mobility vehicle comprises front and rear frame sections which can be disassembled and assembled. The frame sections are secured together by a pivotable detachable connection such that the rear frame section is lockingly received in the rear portion of the front frame section and the length of the assembled frame is substantially the same as the length of the front frame section itself.
