ABSTRACT:
An exercise bicycle including a flywheel assembly mounted on the driveshaft of an hydraulic pump and a load resistance control mechanism for variably controlling the load resistance on the hydraulic pump. A pressure gauge means is also provided to measure the pressure between the load resistance control mechanism and the hydraulic pump so as to serve as an indicator of work rate input. Each of the handlebars of the exercise bicycle is separately pivotally secured to the frame of the exercise bicycle. A linkage means connects the handlebars to the driveshaft in such manner that the driveshaft may be driven by pivotal movement of the handlebars or rotation of foot pedals mounted to the flywheel assembly.
