Abstract: 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 ? 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.

Abstract: A pedal-drive system for propelling multi-wheeled cycles includes two pedal level arms connected to a pair of two-bar linkages, which are drivingly attached to corresponding crank pins on each respective side of a common drive spindle, perpendicular to the cycle frame. The linkages rotate the said spindle per each pedal's downward stroke so that when one pedal arm is all the way down, the opposite pedal's crank pin is already beyond full up position, thus ensuring continuous rotation of the drive system. A sprocket on the spindle drives a chain, that drives a sprocket on a back wheel. For higher speeds, a typical bicycle multi-sprocket-cone and speed changing chain-derailleur may be incorporated. The pedal system may be used for small to large manually powered cycles, particularly scooters and bicycles, and may also include an auxiliary electric motor and battery for propulsion.
