I have a standard 16' wide 2 car garage with an automatic door. I keep 2 cars and 2 bikes in it. I also keep thousands of tools, parts, and supplies in it, and have a workbench. I keep 3 more bikes in what used to be my living room. I didn't need a living room since I live alone, so I converted it to a bike room. It's great, because I can work on bikes in cool air conditioned comfort (70 degrees F) when it is 115 degrees F outside in the summer) I keep my dual sport bike, a parts bike, and some more tools behind the house in a shed I built out of the back patio. I won't even leave a filthy dirt bike outside, as the sun would destroy it, and/or someone would steal it. I won't buy a bike unless I have an indoor place to keep it. I'm at my limit right now.
