Between my wife and 3 y.o. daughter, we've recently added two new bikes and a Burley to the stable. Needless to say, our garage is getting cramped. I've looked at several different storage systems. The one that I think I like best uses a rope and pulley to suspend the bicycle. There are two rubber covered hooks--one hooks under the handle bars, the other on the back end of the saddle--that allow you to raise the bike up toward the ceiling using the rope and pulley.
This would work better for us than wall hooks because my wife isn't very tall, and would have trouble using hook systems. She could simply lower the bike all the way to the ground.
Now I've just got to figure out how to get the Burley off the ground all winter.
