So i plan on getting 2 bikes.. one for myself and one for my gf. Unfortunately, we live in a 1 bedroom apartment.. so.. space is limited. We have a patio area, but i don't really want to leave my bikes outside even if they are locked up.

so i figured we could hang them up on the wall, making use of that space as well as treating the bikes as "art". What are some options for hanging your bikes on the wall? Anything you guys have seen that is secure, yet looks decent, and doesn't cost that much?
