A work control assembly in a bicycle exerciser having a driven member rotatively mounted on a frame. The work control assembly includes a brake which engages the driven member. A lever is pivotally carried by the frame and connected to the brake for exerting braking pressure on the driven member. The brake is spring loaded, the spring tends to resist the pivotal movement of the lever in one direction. A pivotally mounted control arm engages the lever to pivot the lever and to hold the lever in a selected pivoted position against the action of the spring loading. The lever and the control arm are pivotally mounted to a plate which is attached to the frame. The plate includes a plurality of holes located along an arcuate path. The control arm selectively interfits the holes for holding the lever in a predetermined position for determining braking pressure applied to the rotatively mounted driven member.
