Our 18 Bike grid bike rack is a stylish, industrial strength bike rack. It can accomodate up to 18 bikes that can be secured using a variety of locks. We offer it powder coated in black for extra resistance to the harsh weather, but the galvanized metal is very sturdy and is weather resistant on its own if that look fits your facility best. With a capacity for 18 bikes, this rack is great for retail centers, small schools, or offices. Though the in-ground mounting kit is not intended for concrete, the industrial strength construction makes it a heavy duty bike rack even without it.
