ABSTRACT:
An exercise bike includes a support structure with a seat, a handle, a pedal assembly and a resistance mechanism that permits regulation of the effort required to actuate the pedals. The resistance mechanism is housed inside a sealed box that defines a chamber. An inertia counterweight disk is disposed inside the sealed chamber, which also contains a liquid or semi-liquid substance. The level of the semi-liquid substance in the chamber may be varied at will to vary the friction force between the disk and the liquid inside the chamber. Thus, the effort required to pedal the exercise bike is correspondingly variable, based on the liquid level in the sealed chamber.
