I need to find a sensible way of storing my bike. The only suitable
place in my flat is the small corridor by the front door. Not
suprisingly it really gets in the way. Is there a storage system out
there to solve this problem? The corridor is narrow (maybe 4.5 feet)
and quite low (c. 8 feet)... thanks.

I store my bicycle in my garage suspended from the ceiling by 3 rubber
coated hooks. I first lift the bicycle upside down and latch each tire
to a hook. I them push the midsection of the frame up toward the
ceiling where I have a third hook suspended a bit further down on a
cord that I catch to the frame. The whole bike is then flat to the
ceiling with nearly 7 foot of clearance. Hope you can picture this, it
works great for me. The main caveot I suppose is that I can easily
lift my bike in such a manner and understand that many cannot.
