The Saris Cycle Glide is a ceiling storage unit for those with up to 4 bikes. However, with an optional mount for 2 extra bikes, up to 6 bicycles can hang upside down from you ceiling, getting wheels and handlebars completely out of your way. Although it optimizes space by consolidating the bikes, the rides are not crowded together, making it easy to get between them and take your bike down. Sounds better than stowing your wheels away in a closet don't it? This is one of the pricier options though at $207
