This U-lock or D-lock is a sturdy fellow that comes with a bunch of certificates and the required credentials. ART-certification (four stars), Sold Secure GOLD, SBSC- and FG-certification, you name it. Does this imply 100% anti-theft warranty? Alas, everything can be busted and thieves have always been inventive, however, it does create a set of obstacles for anyone malicious.
The basis is a cylindrical shaped double closing mechanism. Oxford added a high-tech pick-resistant locking system which makes the lock virtually impossible to open without a key. We say ‘virtually’, because nothing is ever absolute but our trust in this U-lock is pretty high. And justifiably so. Whoever is discouraged by the lock and double mechanism and searches for its weak spot, will have to measure up against the 16mm-tempered steel shackle. During the development, Oxford unleashed a saw, drill and bolt cutter on the thing. Successfully, or in this case ‘unsuccessfully’.
The – actually usable – height is 27.5cm. Its width 10.5cm. So, motorbike tyre sizes. To be clear, these dimensions are applicable within the shackle. Its total circumference is a lot bigger with its 34 x 17.7cm, which also means you don’t simply carry this big boy in your pocket. Oxford evidently supplies a holder to attach the lock when you’re not using it.
You get two keys and you can order new ones with a number that can be found on the metal tag (which you best not lose too).
As a U-lock, the Magnum offers additional options in combination with chains, cables or fixed anchor points.
