ABSTRACT:
A hydraulically driven bicycle frame with two axle members coupled to the bicycle frame and front and rear wheels mounted on such axles for rotation about the axis of the respective axle and a pair of pedals mounted on a pedal drive shaft coupled to the bicycle frame for rotation for applying manual power for operating the hydraulic system of the bicycle. The hydraulically driven bicycle has a hydraulic pump mechanism and a hydraulic drive mechanism. The hydraulic pump mechanism is operated by rotational movement of the pedal drive shaft. The hydraulic pump mechanism includes a pump housing having two sectional pump housing members that form a pump chamber between them. The two sectional pump housing members are capable of relative movement with respect to each other so that the pump chamber is capable of being varied in size for varying the flow of fluid through the pump mechanism. The hydraulic drive mechanism is driven by the fluid pump by the pump system and is coupled to one of the wheels of the bicycle for providing a rotational force to such wheel. The hydraulic drive mechanism includes a drive housing having two sectional drive housing members which form a drive chamber between them. The two sectional drive members are capable of relative movement with respect to each other so that the drive chamber is capable of being varied in size for varying the flow of fluid through the hydraulic drive mechanism. The hydraulic pump mechanism and the hydraulic drive mechanism are interconnected by fluid circulating tubes so that a closed hydraulic system is constructed on the bicycle.
