GRANIT EXTREME 59 £229.99 www.abus-uk.com The Extreme 59 is like consuming a more affordable Abus X-Plus and putting it on a high-protein diet. In short, this is the toughest U-lock you’ll find on the market – and that applies to motorbikes as well as pedal-powered cycles. 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 truly impressive. Weather resistance is impeccable as is its resilience against lock 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 perfect 10.
A high price but arguably the toughest lock on the market
