Engineered for urban security and trusted by cyclists worldwide, the Kryptonite Evolution Standard U-Lock delivers high-performance protection in a compact, streamlined design. The 14mm hardened max-performance steel shackle resists cutting and leverage attacks, while the patent-pending double deadbolt adds extra defense against twist attempts.

The new smaller crossbar design keeps things tight and lightweight without compromising strength. A high-security disc-style cylinder stands up to picking and drilling, and the 3 stainless steel keys—including one with an LED light—ensure easy, durable access on the go.

Take your lock wherever the ride leads with the included FLEXFRAME-U bracket, and keep your frame scratch-free thanks to the protective vinyl coating. With the Key Safe Program, losing a key doesn’t mean losing peace of mind.
