The average size of a single bicycle storage unit is 6.5 by 2.5 by 4 feet. The average adult bicycle measures 6 feet by 2 feet. To store a bicycle, the inner measurements of any shed should be at least half a foot longer and wider than the bike.
Many storage solution companies offer units that are appropriate sizes for bicycle storage. When storing multiple bikes, width space can be saved by storing them in alternating directions. Bicycle storage units are available in metal, resin, wood and fabric. Factors such as climate, area and number of bikes should be considered when choosing a style and material.
