Last year we put 24 different locks to the test, exposing them to extreme temperatures, cropping, cutting and hammering. That’s how we came up with our list of the best bike locks, and the Kryptonite New York M18 D-lock scored very highly.
It’s a bit of a beast at 2.5kg with a shackle that’s 18mm in diameter. It features a pick-resistant disc cylinder mechanism and stands up extremely well to bolt cropping, sawing, tensile and torsional resistance.
It usually retails for £120, but right now it can be yours for just £67.99.
