ABSTRACT:
A work control apparatus in a bicycle exerciser having a driven member made of inductive material and rotatively mounted on an exerciser frame. The work control apparatus includes a fixing shaft pivotally connected to the exerciser frame and fixedly carrying a pulley member and a box-shaped support portion, a U-shaped permanent magnet secured to the support portion and a rotatively mounted knob connected to the pulley member by an endless belt for selectively locating the permanent magnet in one of a plurality of angular positions. Part of the driven member is interposed between two spaced legs of the permanent magnet to generate an eddy current in the driven member for exerting a rotation resistance on the driven member.
