Kryptonite

KryptoLok LS U-Lock - Double Deadbolt

We're pretty sure there isn't a worse feeling than walking outside of work or class to find your bike is no longer where you locked it up, and Kryptonite feels the same way, which is why its designers pride themselves on making burly locks that you can rely on to keep your ride secure. The Kryptonite KryptoLok LS U-Lock with Double Deadbolt is built to be tough and pick-resistant so you can confidently commute without worries of your bike pulling a disappearing act while you work or study. It uses tough 12.7-milimeter performance steel for the shackle, and a new, Hardened Double Deadbolt design that gives additional protection against twist-attacks. The lock itself features a high-security disc-style cylinder that Kryptonite claims to be pick and drill resistant, and with their 40-plus years of experience, we're not quick to question them.

In fact, Kryptonite is so confident with the KryptoLok LS U-Lock Double Deadbolt that they give it a 6 out of 10 rating on their security scale, covering it with their Anti-Theft Protection to help you recover, should anything happen to your heart and soul while it's locked up outside of the pub or supermarket. The U lock comes along with two keys, so you've always got a backup if you forget one at the office, and a flexframe-U bracket to secure your lock to your frame wherever is most convenient when you commute.
