摘要

A self propelled vehicle driven by the waist via twisting movement. The device has a main frame supported by three wheels, one of which being steerable via a handlebar and the other two wheels being driven by a rotary motion. The main frame has a shaft that has a footboard centrally coupled to the board with a resisting board underneath, the driver unit is located between the two boards and a flywheel is coupled to the shaft with an outer edge joined to the driver unit. Motion transmission mechanism are driven by the rotary motion of the driver unit and the flywheel, the rotary motion being transferred to a pair of bevel gears then a horizontal axle and finally the wheels.
