The DoubleUp Single Sided Free-Standing Vertical Bike Rack is the most effective commercial ultra-high density space-saving bike rack on the market. The DoubleUp Single Sided Units are perfect for bike rooms within multi-family developments and other ultra-high density parking environments. Made with carbon steel, this free-standing frame will hold several bikes securely using the smallest footprint possible. Bicyclists can easily place the front wheel of their bikes on hooks that hold the bicycles firmly off the ground. Hooks are staggered in height so there is no contact between bikes or handlebar to handlebar conflict. The metal locking bars provide two points of locking contact to secure both the front and rear wheels to the rack with either a U-lock or cable. Also included is an attractive imprint of a bicycle symbol that lets cyclists know this is a safe place to store their bicycles and keep passageways clear. When it comes to maximizing space and providing efficient bicycle parking, this is a superb free-standing vertical bike rack – commuter approved!
