The Litelok Silver Flexi-U's flexibility ensures riders have more options when securing their bike. Unlike stiff rigid locks, it is able to bend around street furniture such as sign posts, lamp posts, telegraph poles and trees.



The Litelok Silver Flexi-U has been security tested using common bike theft tools, 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.



Litelok Silver Flexi-U has turned a very tired, and traditionally heavy, product category on its head. Not only is it flexible, it also has the same vertical locking system as the Litelok Silver Flex-O, giving you a downward line of sight making it easier to open and close your lock.
