Patent ID: 7588110

Claim:
A three-wheeled vehicle comprising: (a) a frame for supporting a driver and a plurality of mechanical devices, wherein the frame comprises a front portion, a rear portion, a vertical cross plane, a right portion, a left portion, and a vertical center plane, wherein the front portion is opposite the rear portion and is generally divided by the vertical cross plane, and wherein the right portion is opposite the left portion and is generally divided by the vertical center plane; (b) a pair of steerable front wheels rotatably affixed to the frame positioned at opposite sides of the front portion generally equally separated by the vertical center plane, and wherein the pair of steerable front wheels rotate in both a pair of rolling axes and a pair of turning axes, wherein the pair of rolling axes allow the pair of steerable front wheels to roll upon a surface wherein the surface is substantially perpendicular to both the vertical center plane and the vertical cross plane, wherein the pair of rolling axes are substantially parallel with the surface, and wherein the pair of turning axes are substantially parallel to both the vertical center plane and the vertical cross plane, such that the driver can change direction of the pair of steerable front wheels relative to the orientation of the frame about the pair of turning axes through a driver steering input; (c) a rear wheel rotatably affixed to the frame generally centered along the vertical center plane and positioned about the rear portion behind the vertical cross plane, wherein the rear wheel rotates in a rear rolling axis wherein the rear rolling axis is substantially parallel to the vertical cross plane and substantially perpendicular to the vertical center plane, such that the rear wheel can roll upon the surface; (d) a motor affixed to the frame generally centered along the vertical center plane; and (e) a driver seat affixed to the frame generally centered along the vertical center plane and behind the motor and ahead of the rear wheel, wherein the driver seat is in both a recumbent position and a straddle position wherein the motor separates support for the driver's left and right feet, such that support is connected to the frame for the driver's left foot to the left of the motor in a direction perpendicular to the vertical center plane towards the left portion and support is connected to the frame for the driver's right foot to the right of the motor in a direction perpendicular to the vertical center plane towards the right portion.
