I have three types of bike storage in my garage. The previous owner had installed a Saris sliding bar adjustable rack with inverted hooks. This holds four bikes. Our two mountain bikes are on pulleys for ease of raising and lowering (they're tougher to handle overhead), and the pulley permits my wife to easily retrieve her MTB if I'm not home to do it for her. Third, we allow two bikes to floor stand on either side garage, nearest to the door opening, one for my wife (her daily) and the other, whatever I choose to have handy to ride that day.
