An improved two wheeled reciprocating pedal driven scooter has a frame including a steering assembly attached to the frame, a front steering wheel attached to a front axle attached to the steering assembly at the frame, a rear drive wheel attached to a rear axle attached to a rear portion of the frame and a drive mechanism for rotating the rear drive wheel. The drive mechanism has a pair of reciprocating foot pedals straddling each side of the frame, attached to and extending to a forward proximal hinge attachment location on the frame. Each of the foot pedals has a short portion and an intersecting long portion forming a bend at the intersection wherein an included angle &thetas; between the short and long portions is 90 degrees or greater. The attachment location of the foot pedal to a coupling of the drive mechanism is at or near the intersection forming the bend of the short and long portions of each foot pedal. The proximal hinge location is vertically located on the frame a distance “Y” at or above the center of a drive axle. The short portion of the pedal extends a distance from the proximal hinge location to the intersection of the long portion of the foot pedal to form the bend wherein the bend is located at or below the frame. In use, when the long portion of one foot pedal is at the bottom of the foot pedal stroke it is substantially horizontal while the long portion of the other pedal is at the top of the stroke and is inclined to a maximum stroke angle α of less than 35 degrees, preferably 29 degrees.
