ABSTRACT:
A vehicle powered by an operator's arms and/or legs utilizes a pivot column for propulsion. An upper propulsion member (handlebar) is provided on the upper end of the pivot column. A lower propulsion member (foot bar) is provided on the lower end of the pivot column. A drive propulsion system is provided between the pivot column bottom and a rotational drive gear set. The drive propulsion system engaged with said at least one rotational drive gear, the propulsion system engages with and provides propulsion to an upper portion of the rotational drive gear during a counterclockwise motion of the pivot column and engages with and provides propulsion to a lower portion of the rotational drive gear during a clockwise motion of the pivot column. The rotational drive gear spins freely when subjected to the reverse motion. Incorporating two gears with opposing propulsion drives provides forward motion throughout the entire reciprocating stroke of the pivot column.
