In reply to balmybaldwin:
My wife doesn't use her bike much so we will keep that in the flat. I use mine eveyday and it would be a hassle to cart up & down (second floor) all the time (as well as keeping both bikes in the flat).
Going to put up some notices in the close (shared stairwell / hall for those who don't know what a 'close' is).
About a fortnight ago wheelie bins were set alight in our back lane. Seems the devil is finding work for idle hands.
