The lock protects your bike from casual and opportunistic theft, so you can enjoy your well-deserved break with peace of mind. As the steel cable is extendible, it can be threaded through the bike to be secured and locked in no time at all. To open, simply enter the opening code that you choose yourself. The cable will then automatically retract itself. The Combiflex provides convenient keyless security in a handy format. This means that loose objects are also protected from nimble fingers.
