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.
Claims10
An exercise bicycle, comprising:
- a frame;
- a positive displacement hydraulic pump mounted on said frame, said pump having a pair of inlet/outlet passages and a driveshaft for operating said pump;
- a pair of foot pedals connected to said driveshaft of said pump for rotating said driveshaft;
- a load resistance control means operatively connected to said pump for selectively controlling the load resistance on said hydraulic pump and automatically maintaining said load resistance constant at varying speeds of said driveshaft, said control means defining a valve body and valve seat in flow communication with said inlet/outlet passages;
- and
- a hydraulic pressure gauge means in fluid communication with said pump and said load resistance control means, said hydraulic pressure gauge means serving to indicate work rate input of an operator actuating said exercise bicycle.
An exercise bicycle, comprising:
- a frame including a pair of handlebars separately pivotally secured to said frame and operable in pivoting and stationary modes;
- a flywheel rotatably mounted on said frame;
- a pair of foot pedals actuable by an operator to rotate said flywheel;
- a load resistance control means operatively connected to said flywheel for variably controlling the load resistance on said flywheel;
- a linkage means releasably linking said flywheel and each of said handlebars, said linkage means for permitting said flywheel to be rotated by pivotal movement of said handlebars;
- and
- a locking means for rigidly securing said linkage means to said frame thereby rigidly securing said handlebars in said stationary mode.
