The above would indicate that should you own a £400 bicycle (a typical value in the UK) you'd purchase a £40 lock and put it in the correct place.

If there's a valuable half that can be removed with hand tools he will take it. He is especially keen on premium saddles and name brand wheels. Percy has a small collection of electric and air instruments together with an angle grinder in addition to bolt-cutters and an air-jack.

He has entry to criminal fences which he can use to sell stolen bicycles quickly. Percy often arrives in his van and this allows him to steal a number of bikes directly. No bicycle is safe from Percy. No lock can hold towards his angle grinder.
