The two dollar hook screwed into the wall is the cheapest route. I have a couple of wall mount racks that work on the same principal as a hook in the wall, but it has hooks for two bikes and two shelves in between for gloves, helmets, shoes, etc. Sorry, no pictures but its pretty slick. Not sure who made it. I also have hooks in the ceiling and some bikes hanging above said wall mounts, and couple of hooks with old wheels, etc. (Too many bikes and bike stuff at my place!) I'll see about a picture of my wall mounts later today.
