How to store bikes inside a house or unit with limited internal space? Between my girlfriend and myself, we have 5 bikes of which 3 would ideally be stored inside (the two road bikes and my duallie). However, my house is a relatively small terrace house which doesn't have huge spare rooms on the ground floor for bike storage.

What is the best storage solution you've seen for keeping the bikes inside that:


Is compact and keeps the bikes relatively out of the way,
Allows the bikes to be easily accessed for going on rides,
Preferrably doesn't involve permanent fixtures on the wall, and
Looks good?
Friends of mine use a Two-Bike Gravity Stand, and are really happy with it.  It doesn't require any modifications to your apartment, and does a pretty good job at keeping the bikes out of the way.  For myself, I installed a pulley system, but that does involve drilling in the ceiling.
