A bicycle parking rack, usually shortened to bike rack and also called a bicycle stand, is a device to which bicycles can be securely attached for parking purposes.[1][2][3][4] It may be freestanding, or securely attached to the ground or a stationary object, such as a building. Indoor racks are commonly used for private bicycle parking, while outdoor racks are often used in commercial areas. General styles of racks include the Inverted U, Serpentine, Bollard, Grid, and Decorative.[5] The most effective and secure bike racks are those that can secure both wheels and the frame of the bicycle, using a bicycle lock.
Bike racks can be constructed from a number of materials, including stainless steel, steel, recycled plastic, and thermoplastic. Durability, weather resistance, appearance and functionality are important factors when choosing this material.[5]
The visibility of the bike rack, adequate spacing from automobile parking and pedestrian traffic, weather coverage, and proximity to destinations are all important factors determining usefulness of a bicycle rack, helping to increase its usage and assure cyclists that their bikes are securely parked.[6]
