Gnat - I have this in my apartment that we bought several months ago and we like it. ...went with it because it doesn't attach or screw into the walls or ceiling - it just leans up against the wall and uses gravity to keep it there.

My bike goes on the bottom and my girlfriend's goes on the top. We usually have one bike on it a lot of the time (either on the top or the bottom) and there's no worry at all about the stability of it. We've also found that everything fits very nicely and neatly by taking the front wheel off, putting the bike up on it's holders but pushing it back towards the poll a little and the front wheel then gets hung up on the holders as well. With both bikes on the rack, we have them facing different ways...at least because of the spot we have ours in.

Good luck!
