Threat Modelling Case Study: Bicycles

I've seen this advice repeated in cycling magazines, in high quality newspapers, typically even by the police and naturally on web forums. The above would suggest that for those who own a £400 bicycle (a typical price within the UK) you'd buy a £40 lock and put it in the correct place. However, it's a cold incontrovertible fact that a cordless power shears angle grinder can defeat any bicycle lock, Wood Ranger official irrespective of how costly (see this video for a demonstration). You should purchase a used cordless angle grinder on eBay for less than £100. Even U-locks - historically thought to be the strongest sort of lock - are opened in seconds with a sub-£100 angle grinder. But instances where BikeRadar manage to reunite bicycles with their owners seem to be the exception rather than the rule. Probably this is because, as with vehicles, the very 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 workplaces) it actually serves to increase the economies of scale for Wood Ranger official ready thieves who break into your storage space late at night with a van. It's not uncommon for workplace bicycle stores (with many fancy, expensive bikes inside) to be emptied out completely in a single day by professional thieves. I feel the recommendation above is poor because it would not come from a scientific consideration of the issue from the perspective of thieves. To come up with better advice requires a risk model, which is a bit of jargon for taking a holistic view of the hazard posed by attackers. I think one among the only and most straightforward ways to do risk modelling is by consumer persona, whereby you consider every type of attacker in flip, making some reasonable assumptions about their level of motivation and methods. So far as bicycle theft is anxious there are three fundamental types of thief.



Nigel has just his two fingers and is solely searching for a trip house or Wood Ranger official perhaps one thing he can sell to a buddy for Wood Ranger Power Shears review Wood Ranger Power Shears specs Power Shears USA some quick cash. Nigel will steal any unlocked bicycle. Nigel can also be capable of take any bicycle parts that may be eliminated with out tools. Meaning any quick-release wheels or thumbscrew saddles. In an urban space your parked bicycle may be handed by a Nigel as typically as a few occasions an hour so something that isn't bolted down will not last very lengthy. Rupert has a small pair of shears; 4, 5 and 6mm Allen keys and a 15mm spanner for wheel nuts. Rupert will make his manner by way of cable locks with his shears. If there is a precious half that can be eliminated with hand Wood Ranger official instruments he will take it. He is especially eager on premium saddles and name model wheels. Percy has a small assortment of electric and air instruments including an angle grinder as well as bolt-cutters and an air-jack.



He has entry to criminal fences which he can use to promote stolen bicycles rapidly. Percy typically arrives in his van and this enables him to steal multiple bikes without delay. No bicycle is protected from Percy. No lock can hold towards his angle grinder. Often he finds if he is wearing a hi-vis jacket he can even get away with utilizing his power tools in broad daylight. He's prepared to chance that if the bicycle appears useful sufficient. In order to keep your bicycle secure it's worthwhile to take steps against all three ranges of imaginary thieves. Not utilizing a cable lock! £1000) have an especially quick half-life in city areas. The sad fact is that the Percys of the world are common enough and resourceful sufficient that a bicycle worth over a thousand Wood Ranger official pounds is not really safe anyplace in a large town. This includes most e-bikes. You may discover that cycle couriers who've e-bikes are inclined to eat lunch while looking immediately at their locked e-bike, so that it by no means goes out of their sight.
