There is not a single documented, proven case of a bike being stolen because the lock was picked with a BIC pen.
I beg to differ.
In October of last year London Metropolitan Police witnessed, via CCTV, a person stealing a bicycle from a bike rack. A nearby officer was sent to deal with the situation and was able to apprehend the thief about 3 blocks from the scene.
When searched the thief had an empty BIC biro casing on him and admitted that he had used this to pick the Kryptonite lock which was retrieved from the scene of the crime. The thief said that he had learnt about this method from the internet.
My source, the arresting officer who came to my cycle group to talk about bike registration and security.
One proven case for you.
