If you're short on horizontal space, but have a bit of vert to work with, the Feedback Sports Velo Cache 2 Bike Storage Column is an ideal solution. It's built from aluminum, and is incredibly sturdy, and utilizes a three-legged design to ensure your prized steeds never hit the ground unexpectedly. And, while it holds two bikes in this configuration, Feedback offers a kit to turn the Velo Cache 2 into a Velo Cahce 4, doubling its capacity while only marginally increasing its footprint.
