Bike racks can be constructed from a number of different materials. Durability, weather resistance, appearance, and functionality are extremely important variables of the material of the bike rack.[from wikipedia]

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. These factors will help increase usage of the bike rack, and assure cyclists their bike is securely parked.[from wikipedia]
