I thought about hanging mine, but since I have a large basement mostly unused I made a bike rack out of PVC bike for 7 bikes, with room to add if I ever need to. This way I don't have to lift a bike up every time I want to use one, which isn't a big deal, just for me a bit more convenient to have them on the floor. And the rack is against one wall of the basement so the space their taking is not all that much.
