Maybe slightly offtopic…
I had a bit of an ongoing argument with some of the guys from Cycling Plus a while back re their lock tests, because they were using methods that weren’t appropriate for quality locks- prybars, small hammers, hacksaws, pliars and the like. As a result, some pretty substandard locks got a good mark.
The response was that they’d set the test based on their conversations with the Met on what tools are actually used, and that almost all bikes were stolen with this sort of tool.
So the conclusion was, most bikes stolen have absolutely appalling locks, and that either few bikes are locked up properly, or those few that are tend to be bypassed because there’s so many easier targets. Like swimming with sharks, basically.
Anyway- I’m half-assed about security, never had a bike stolen.
