Good quality shed. Double padlocks, again good quality, hasps that cover the screws
Hinges, extra long security screws.
Shed alarm
Bike inside shed, chained to side of shed wall with good quality chain and Padlock bolted to frame of shed with m8 bolt through main support, double lock nuts with full bottle superglue all over nuts and bolt. (Could not at time find a way to secure bike in shed as shed base is lifted up, so can't use anchor bolt as can't get under shed and to high from ground to drill through)
They obviously for me, scouted shed out befoehand and bought the tools they would need, had security screw tool, as removed shed door via screws. Never heard alarm, which they took with them, random. Bolt cut off and nuts undone, took chain that was still on bike. They then put shed door back in place so you would have to go up to shed to realise they had removed screws ☹
