Threat Modelling Case Study: Bicycles

I’ve seen this recommendation repeated in cycling magazines, Wood Ranger Power Shears website in quality newspapers, generally even by the police and of course on web boards. The above would imply that when you own a £400 bicycle (a typical worth within the UK) you’d purchase a £40 lock and put it in the suitable place. However, it is a cold incontrovertible fact that a cordless angle grinder can defeat any bicycle lock, no matter how costly (see this video for Wood Ranger Power Shears website a demonstration). You should purchase a used cordless angle grinder on eBay for lower than £100. Even U-locks - traditionally thought to be the strongest sort of lock - are opened in seconds with a sub-£100 angle grinder. But circumstances where BikeRadar manage to reunite bicycles with their homeowners seem to be the exception rather than the rule. Probably it is because, as with cars, the first thing you do with a stolen bicycle is take it throughout a border to somewhere different.


This prevents opportunistic theft but if this area is shared with others (residence blocks and offices) it in fact serves to extend the economies of scale for prepared thieves who break into your storage space late at night time with a van. It’s not uncommon for office bicycle stores (with many fancy, expensive bikes inside) to be emptied out utterly in a single day by skilled thieves. I think the advice above is poor as a result of it does not come from a systematic consideration of the issue from the standpoint of thieves. To come up with better advice requires a risk mannequin, which is a piece of jargon for taking a holistic view of the danger posed by attackers. I think considered one of the simplest and most easy ways to do risk modelling is by user persona, whereby you consider every type of attacker in flip, making some reasonable assumptions about their stage of motivation and methods. So far as bicycle theft is worried there are three primary forms of thief.

In an urban space your parked bicycle could also be handed by a Nigel as often as a number of times an hour so something that isn’t bolted down will not final very long.
