I’ve got my FS in the shed. I bought two old, steel and extremely heavy bikes off of that there Gumtree for a few pennies. They are securely D-locked either side of the FS with two D-Locks. So should Mr A.N.Other scrote get access into the shed (past the flimsy door which has – annoyingly for said scrote – two noisy wheelie bins chained through the padlock), he/she/it will have to either cut through two D-locks in an annoyingly dark and inaccessible place (angle grinder or carjack required), or manually widen the shed door prior to manually lifting out about 50 kilos worth of bikes and having it off on their toes down the alley. All this of course whilst the dog is going mental in the kitchen and I’m belabouring him/her/it around the head with my Maglight, having first shone it into their eyes in order to blind them.
Nothing’s foolproof mind, but given that the average thief is after an easy touch, the more difficult you can make it the better.
And when all is said and done a large canine with a good bark is probaly the best insurance you can get
