Years ago I lived in a studio apartment in San Francisco (back when one could afford to do so). The bedroom was the living room was the dining room, small kitchenette off to the side. I did have a "walk in closet" which was used to store 4 bikes in the manner of [MENTION=185430]dddd[/MENTION] (above). One of the was a Bike Friday, which stayed in the suitcase most of the time, another was a Fisher tandem, also a mountain bike and a road bike. I remember measuring it, and the four bikes took up 4 linear feet of the closet. I had to turn sideways to get around them to get to everything else, but hey, one has to have priorities, right? Bikes gotta be near the front door, ready to go.
