The first thing that popped into my head is "how do you lock that bike up?"

I love bikes as decor

That was my thought too. 'Oh, it's inside, because it's impossible to lock up securely.'

I have what I consider to be an awesome looking bike (brompton folding), but even that goes into the closet in a spot made for it, because street grime and bike grease is just not that appealing in a house.
