So I just moved to a new apartment and want/need to get a bike rack for my two bikes. I was looking at the ones that just lean against the wall, since I don't want to put big screws in the wall and the ceiling will not work with a floor ceiling system. I was wondering if anyone had one, especially the wooden ones and know how well they work. I dont really want my bikes falling over or on me. Or slipping across the floor. Thanks
