Damn… 
I can only imagine what it’s like going through that…
i would go and buy a couple of alarmed disc locks and a baby monitor set, if the locks are played with the go of, set the baby monitors to maximum volume and hide them as close to the locks as you can. inside a garage the sound should be slightly amplified, and when it goes off you will hear it.
also as said go over all your chains, make sure no links have been tampered with or cut and replaced with a cable tie…
if you wanna really scare them, get some shotgun mines 
Hey guys. all the bikes have been relocated to either friends or work 
only Claires Beemer left as she commutes but thats Almaxed to the bbq in the shed. I ordered a PIR sensor with 130db alarm so we should be good. I dont want a baby monitor as I’ll be jumping at every sound.
Homefully this will sort it until we move (if we can) 
So true :crazy:
Can you not wire up a handle or something to the mains?
Easy to get rid of too once it’s done its job (just wire it back up to a lamp, extension cord), leaves no marks / scars etc
Some bright spark did that to his front door in manchester a few years back, zapped a fireman who was trying to evacuate the flats & got locked up as a result.
No offence, but what you would evacuate from shed?
