High Quality Content by WIKIPEDIA articles! A bicycle stand, also called a bike rack, is a device to which bicycles may be securely attached. It may be free standing or securely attached to the ground or some stationary object such as a building. Indoor bike racks are commonly used for private bicycle parking, while outdoor bike racks are often used in commercial areas. General styles of racks include the Inverted U, Serpentine, Bollard, Grid, and Decorative. The most effective and secure bike racks, with the exception of the bike locker, are those that can secure both wheel and frame of the bicycle, using a standard U-lock or cable.
