Versatile Style & Use Case

Ideal for protecting high-value bikes in urban environments, the Kryptonite Evolution U-Lock is designed for frequent use in city streets, bike racks, and transportation scenarios. Its compact size (11.5 inches long with a 4-inch shackle width) makes it easy to carry without sacrificing strength, making it perfect for everyday commuting, bike theft prevention, and securing expensive road, mountain, or electric bikes.
