The Extreme 59 is like taking an X-Plus and putting it on a high-protein diet, this is the toughest U-lock you’ll find. With a torsional resistance that’s 1000Nm higher than its nearest rival, and tensile resistance that would handle a couple of vans pulling on each end, it’s impressive. Weather resistance is impeccable as is it’s resilience against picking. Under bolt cropping it’s in the top three of all the locks tested. If you prize your bike and have somewhere to store your lock when not using it or want something tough for home use then the Extreme is perfect. The high price holds it back from a full five-star review.
