ABSTRACT:
A three-wheel exercise vehicle that may be operator pedaled by means of a crank assembly that is coupled by a transmission to a wheel. In addition, an internal combustion engine may power this wheel. The pedal-operated crank assembly is also coupled to a hydraulic pump that pumps fluid through a closed circuit including a restrictive orifice for acting as a brake on the speed of the vehicle when coasting and also providing a load for the operator to exercise when the vehicle is being powered by the internal combustion engine. An improved seating arrangement is provided that will afford great comfort for the operator.
