My advice would be…..
Don’t post pictures of your shed on a website for owners of expensive bikes……and follow it with a discussion about the sheds weaknesses.
I don’t really buy that. I posted pictures of my bikes, the (weak) bike shed, and even links to routes starting at my house for 18 years from the old place. Never once had a bike stolen, not even an attempt.
As I said, anyone who steals my bikes is going to be very disappointed anyway. None of them cost more than a grand when new, they’ve all been ragged senseless and I don’t look after them very well.
I reckon most thieves look for either very specific, expensive bikes on forums like this or local thieves see you riding about and follow you home. Neither of these things is likely to happen to me. [1]
