The security standards are a bit of a joke tbh. Only really relevant for insurance purposes (they’re based entirely on attacking the locks with the wrong tools “This lock stood up to our hammer attacks and took 2 minutes to grind through!” but it cut in 2 seconds with a boltcutter. Or likewise trying to cut cable locks with a hacksaw instead of a cable cutter. Nonsense like that.
(the justification is that most bikes are stolen with these tools- which is true, but most bikes are badly locked. Testing half-decent locks with the tools that work on useless locks is absurd. Most people murdered are murdered with knives, so we’ll test this bullet proof vest against knives not bullets!)
Anyway. How much of a ride is it? got space for another bike? A cheapo commuter/pub bike costs less than a good quality lock and also protects your wheels, saddle, etc.
