Abstract
In a "bicycle" type exerciser in which a wheel on which a tire is mounted is supported for rotation off of the ground between two spaced legs of a fork, and a tension device is mounted to apply a selected braking force to the wheel, a head plate extending between and secured to the fork legs above the wheel has at its lower edge an outturned lip. A down tube is secured at its upper end to the head plate and extends downwardly from a position above the wheel in a direction rearwardly away from the wheel. A yoke, U-shaped in plan view, has two arms embracing the down tube and a bridging section between them at one end of the arms extending across the down tube. A tension wheel is mounted between the arms at their free ends. Each of the arms has a knuckle member engaging the lip of the head plate to form a hinge connection. A tension screw, with a knob on its outer end, is threaded through the bridging section and extends through a slot in the upper surface of the down tube to engage the lower inside surface of the down tube and to rock the yoke about the hinge to move the tension wheel into tighter or looser engagement with the wheel.
