We live in a flat/apartment so space is tight (especially when your a seven bike family - don't ask)
While making a custom saddle for the wife's newly pimped trike I noticed an interesting feature of the saddles sprung bracket - as you see from the picture.
So I dug out a spare - and now we can store our uni's --- well - - up. The funniest place we tried is in the coat cupboard, coat, coat, scarf, coat, unicycle, coat - - - - huh! whazzat!.
I am sure you will find your own storage area, be it wall or roof etc.
Step 1: Ok
Only tool I really used was a spanner to undo the sprung bracket from the saddle - if yours is riveted on then a drill will be a must.
Your gonna need the kind of bracket with springs - no probs though as a lot of old bikes have that kind.
