Abstract
A stepper scooter provides step pads that are connected to a laterally arranged rocker bar assembly. Vertical movement of the step pads causes the rocker bar assembly to reciprocally pivot which translates drive chains which cause rotation of the drive wheel or wheels. The rocker bar assembly comprises two four bar linkages between a center fork and each step pad. An alternate embodiment uses the rocker bar to reciprocally rotate a gear axle which drives a bevel gear arrangement to rotate the drive wheel or wheels via one-way bearings. Another embodiment incorporates a chain and sprocket drive between the bevel gear arrangement and the drive wheel or wheels, wherein the one-way bearings are replaced with a one-way sprocket drive.
