Litelok Flexi-U Silver This bike lock has a flexible strap, allowing you to stretch, twist, and bend it to fit any fixture, giving you more options in securing your bike.

Like other bike locks, the Litelok Flexi-U Silver lets you secure your bike in a permanent fixture, making it just a tad more difficult for potential thieves to steal. Unlike them, it uses a flexible design that allows you to secure the bike onto almost any secure fixture you can find.

Billed as “the world’s first flexible insurance-rated U-lock,” the contraption takes the same familiar shape as traditional U-locks, so cyclists can mount it onto their bike frames, backpacks, and any other gear the exact same way. Instead of a solid chunk of metal forming the U-shape, though, it uses a flexible but similarly protective material, allowing you to stretch, twist, and bend the lock to accommodate the most unconventional fixtures.

The Litelok Flexi-U Silver combines a lock made from hardened aerospace-grade steel alloy with a body the outfit calls a Boaflexicore strap. Yeah, we have no idea what that is, either. Fortunately, they elaborated a bit, explaining that it’s a mix of high tensile steel and a complex polymer composite, allowing it to resist cutting as well as traditional bike locks, all while gaining flexible properties that makes it much more versatile on the road. That way, you don’t need to find the perfect post or railing to secure your bike on, allowing you to use more unconventional fixtures to hold the darn thing in place.

Want to secure you bike to the trunk of a tree on the sidewalk that a regular U-lock won’t fit on? This thing just might be able to wrap its way around it. What about a fire hydrant? Well, you might have to stretch it a lot to get it to fit, but you definitely have a better shot than a regular all-steel bike lock. Of course, we’re not sure how legal that is, either, so try at your own risk.

The Litelok Flexi-U Silver comes in two sizes, regular and large. If you’re buying this for the flexible function, you might as well get the large, as it gets you a lot more of the strap, which should expand your options significantly. To keep your bike protected while it lies unattended on urban sidwalks, it uses a disc cylinder that’s resistant to both picking and drilling, as well as a supposedly secure “line of sight” locking mechanism. Yeah, we’re not sure what that means either, but it sounds like clever marketing language that suggests it’s a good thing.

How secure is all this? According to the outfit, it has been security-tested using common bike theft tools to simulate real-world threats, all while being put under duress in lab conditions using machines that apply great amounts of force, both of which should keep some of your fears in check. More importantly, though, it received a silver rating from UK testing organization Sold Secure, so it should offer a pretty decent deterrent. Yes, we’d prefer a gold rating, as well, but the convenience of being able to lock onto unconventional fixtures should make it worthwhile all the same.

The Litelok Flexi-U Silver is available now, priced at $100.
