Claims21
A personal mobility vehicle comprising:
- a frame with a central vertical plane extending vertically through a longitudinal axis of the personal mobility vehicle, the frame comprising:
- a front portion extending along the vertical plane;
- and
- a rear portion coupled to the front portion, the rear portion comprising a first leg and a second leg, the first leg and the second leg extending laterally outward from the vertical plane;
- a seat connected with the frame, wherein the seat is adjacent to an intersection of the first and second legs;
- a front wheel rotatable about an inclined steering axis;
- a first rear wheel connected with the first leg and a second rear wheel connected with the second leg, each of the rear wheels configured to rotate about a rotational axis and swivel about a swivel axis;
- a front fork connected with the frame and rotatable about the inclined steering axis, the front fork supporting the front wheel, and the front fork comprising a first inclined support on a first lateral side of the front wheel and a second inclined support on a second lateral side of the front wheel, wherein each of the supports comprises an upper end that curves laterally outward to form a handgrip, wherein the handgrips are configured to provide steering of the front wheel;
- a power source;
- and
- an electric motor operably connected with the power source, the electric motor being operably connected with the front wheel to provide rotational force to the front wheel.
