NEW YORK M18
The New York M18, from the most famous lock manufacturer in cycling, is a beast at over 2.5kg. Throw in a massive 18mm diameter shackle and it’s clear that this is built of sturdy stuff. The double deadbolt mechanism is centred inside the ovalised crossbar using a pick-resistant disc cylinder mechanism, which works rather impressively. The New York scores well when it comes to its resistance to bolt cropping, sawing (best on test), tensile strength (best on test) and torsional resistance (runner up). With only its middling performance against the angle grinder going against it, the New York is a tough U-lock built the classic Kryptonite way. It may not be as clever as an Abus in its design but the results are much the same.
