A stationary exercise apparatus intended to simulate the action of pedaling a bicycle includes a base and a flywheel mounted on the base for rotation about a vertical axis. The flywheel is coupled in driven relationship to a pair of pedal cranks mounted on the base. The pedal cranks are mounted for rotation about a horizontal axis as in a conventional bicycle. Preferably, the flywheel is mounted directly below the pedals on a shaft whose upper end is formed to be a worm, the worm being driven by a drive gear attached to the pedal cranks. The orientation and location of the flywheel add to the stability of the exercise device as well as aiding in the outward appearance of the device.

A system for selectively positioning one end of a treadmill running machine at one of the plurality of locked positions in order to provide an inclined running surface. A support assembly having a ground engaging roller disposed between a pair of arms is pivotally connected to the frame of the treadmill for swinging movement between a retracted position adjacent the frame and one of a plurality of downward, extended positions. So that the treadmill may be easily raised and lowered to a desired operating position, a gas spring is provided for each of the arms of the support assembly. The upper end of each gas spring is securely connected to the frame, while the lower end is pivotally attached to its respective arm. To maintain the support assembly in one of its extended positions, a slide-tube assembly having a releasable clamping sleeve is associated with each of the arms and pivotally connected to the frame and arm to accommodate the swinging movement of the support assembly.
