That Omni rack is NICE!!! If I had the space I would get me one!!
I did a
helluva lot of online window shopping months ago when we were all talking about gym shut-downs. Before that I never knew there were more than a few folding racks in the marketplace. You have to have the situation at home, and the basic skills, to bolt them to the wall somewhere, but some use the same 3" x 3" 11gauge steel that is the industry standard. The idea is they fold out for use and fold flat against the wall for storage ... instead of only parking 1 car in your 2 car garage, you can still park 2 cars when the rack is not in use.

only sells this type rack, plus space-saving accessories. There may be better versions offered on some of the better known sites ("may be," I'm not sure), but the prx site will give you a good idea of what's possible.
