ABSTRACT:
An exercise bicycle includes a frame body with a seat and a pair of handles. A chain transmission is provided on a lower part of the frame body. The chain transmission includes two chain wheels and a chain. A pair of foot pedals are pivoted on a rear chain wheel. A pair of discs are attached to a front chain wheel and driven by the pedals via the chain transmission. A pair of casings are fixed on both sides of the lower part of the frame body for encompassing the chain transmission. A brake unit is fixed relative to the frame body at a position located between the discs and is actuated by a controller via a cable so as to brake the discs. The frame body has a base with two pairs of extendible shafts for providing a larger base area for the exercise bicycle.
