I put two nails in the ceiling 5 or 6 feet apart. When I want to work on a bike, I hang it from the nails with two old inner tubes. One under the seat, and the other around the handlebars. The distance between the nails keeps tension on the inner tubes and holds the bike steady. I double the inner tubes over to have the bike hang at a good height for working on it.
Unfortunately, I had to leave this bike stand behind when I sold the house.
