Abstract
A hydraulically driven, two-wheeled pedicab constructed with an enclosed cockpit for inclined positioning of a solo rider. The pedicab includes a reciprocating piston pump hydraulically connected to a hydraulic, rotary motor for powering at least one of the wheels, and, a power reserve having a rotary converter for selectively converting hydraulic fluid energy into a stored, compressed gas potential energy, the stored energy being selectively cycled into fluid energy when desired for assisting in the propulsion of the pedicab.
