We have 8 bikes in the house right now, and a 9th out on loan, it's ridiculous. We are over capacity but neither of us is ready to dump any of the bikes.

We have bike racks scattered throughout the house that hold two or three. We've had the wall kinds before but I prefer the floor ones for ease of use (since we have the space). The only bike that lives in the garage is my old townie hybrid, which I'm not ready to break up with because it IS nice for a quick errands run or for commuting in the rain, but also if it were stolen it wouldn't break my heart.

I'd really strongly recommend against keeping bikes in your garage. I live in a high bike theft area (or just outside it), and 95% of the time bikes are stolen its either because they were secured when out and about with a cable lock, or because they were in the garage.
