Kryptonite Lock Kryptolok U-lock

Kryptonite Kryptolok U-Lock – Solid Security for Everyday Riders

The Kryptonite Kryptolok is a go-to U-lock for daily commuters and urban riders who need reliable, high-quality protection without the bulk. Built around a 12.7mm hardened performance steel shackle, it’s designed to resist cutting, prying, and twist attacks—thanks in part to Kryptonite’s patent-pending Double Deadbolt system.

A high-security disc-style cylinder resists picking and drilling, while a protective vinyl coating helps guard your frame from scratches. The lock comes with two stainless steel ergonomic keys that won’t easily bend or break, and a dust cover to keep the internals clean.

Need to take it with you? The included FlexFrame-U bracket makes carrying the lock easy, letting you mount it in multiple positions on your bike.
