Bike Storage: Wall mounts, stands, lock-ups, sheds, etc.

RPM you could also get a bike hanger to go up on the wall in the hall (if there is space and enough height) which would mean it's hardly a fire hazard if it's up off the floor and not in the way.

Exactly. You can even do it with a couple of shelf brackets with something round the end (old inner tube) to stop it sliding off by accident. As long as it's high enough that the outside crank/pedal's not going to whack someone in the face, bob's yer mother's brother. Convince them that deep down they ARE reasonable people :)
