Modular bicycle rack

A stand for bicycles or other two wheel vehicles includes a base unit with two staggered wheel supporting cradles and a plurality of add-on units. Vertical uprights for each cradle define spaces or slots for the front wheels of two bicycles extending in opposed directions. Each base unit supports four bicycles and each add-on unit, two bicycles. When the base and add-on units are connected the uprights which define the wheel receiving slots are located along two parallel spaced axes. Such an arrangement provides good stability, utilizes a minimum amount of framing material and provides a compact arrangement for closely locating bicycles in a relatively small storage space.
