    Abstract: An exercise stand adjustable to accommodate standard size bicycles and pedalling in a stationary position. The base is Tshaped and has a U-shaped bracket with opposed upright arms seated on the leg of the base. Attached to the bracket are fore and aft angled braces supporting the arms. Vertical plates for rear axle support are anchored to and extend upwardly of the arms and carry at their lower ends turnbuckle-operated hook devices to releasably engage rear fork tube frame members of a bicycle and thereby clamp the wheel of the bicycle in an elevated position. The plates can be mounted at selected elevations for different size bicycles. Mounted adjacent the rear of the leg of the base is a lever carrying a tire presser roll to adjust resistance to pedalling.
