Twin Litelok Silver allows you to join two locks together to make a double length lock or use them separately for double security. Both operate from the same set of unique keys. Individually, the Litelok Silver 85 is the world\\\'s lightest secure bike lock range ever made. It is 40-50% lighter than equivalent U/D locks, chains and armoured cables, weighing in at only 830g. The integrated design means that your lock is in one piece, so you don\\\'t have to struggle trying to fix separate parts together and it doesn\\\'t rattle when being carried. It is also flexible, allowing you to secure your bike to more objects, and even wear it around your waist. Made possible with the clever adjustable clip-on Litelok wearable kit, sold separately. It is designed to fit most ages, sexes and sizes (see size charts). When worn around your waist it\\\'s barely noticeable. Litelok Silver is made from high quality materials that are robust and durable. Their patented Boaflexicore strap contains a high tensile steel and a complex polymer composite and the lock is made from hardened aerospace grade steel alloy. Litelok Silver has been security tested using every common bike theft tool, simulating real life street theft attacks as well as being tested under lab conditions, using machines that can apply forces far greater than any human can. Importantly, Litelok Silver has been awarded a Silver rating by Sold Secure, the UK\\\'s leading independent testing organisation, which is owned by the Master Locksmiths Association.
