Ours are in the garage - all over it. Between the junk, the tools and all the biking stuff, we no longer park our car in there. The previous owner had 4 hooks in the ceiling for bikes, so we use those. One bike is usually on the work stand and the rest are propped up around the rest of the garage. I think we have 8 or 9 right now (most belong to my H), but that is constantly changing as he's got a sickness when it comes to bike.

I may suggest that we move the good weather road bikes into the basement once the winter rain arrives. It would be more secure down there, I think.
