+1, an easy fix.
I have hung bikes on ropes from the garage roof trusses. An easy way is to hang each bike from 2 looped ropes--one for the handlebars and one for the saddle. You don't even need hooks--just knotted loops in each end of the ropes.
Also, racks are available that lean against the wall and hold 3 or 4 bikes in the footprint of 1 bike. I bet there are even DIY videos on youtube for making your own leaning rack.
