With the advent of cordless angle grinders, the reality is that no lock is more than 30 seconds away from being cut. Whilst it's no doubt possible to freeze a lock and shatter it, the practicality of doing it would be beyond most bike thieves. Industrial cable cutters, big bolt cutters and long crowbars would be the most common tools.
I reckon the only sure-fire way to make sure your bike isn't stolen is to park it next to a better bike that has a worse lock. |
