High-Security Kryptonite Evolution Series U-Lock 3.25 x 7" with 4' Cable - Robust Theft-Resistant Bicycle Security

Elevate your bike security with the Kryptonite Evolution Series U-Lock, designed for cyclists seeking maximum protection against theft. Constructed from hardened MAX-Performance 13mm steel, this high-security U-lock offers unparalleled durability and resistance to bolt cutters and leverage attacks, making it ideal for urban environments, high-theft areas, or valuable bike assets.

Materials & Performance

Built with premium, hardened steel components, the Kryptonite Evolution U-Lock features a robust 13mm steel shackle that withstands cutting and prying attempts. Reinforced cuffs over the crossbar and high-security disc-style cylinder protect against picking and drilling, ensuring your bike remains secure. The compact design, with a 3.5-inch shackle width and 7-inch length, allows for versatile locking options while maintaining a small footprint for easy transport.

Components & Technology

Equipped with a secure disc-style cylinder resistant to picking and drilling, the lock includes a Transit Flex Frame Bracket system that fits securely on various bike frames and accommodates multiple off-set configurations. The lock comes with three stainless steel keys-two standard "I" keys and one LED lighted key for easy operation in low-light situations. The additional 4-foot cable provides flexible locking options for accessories or auxiliary bike components.

Style & Use Case

Designed with both style and functionality in mind, the Kryptonite U-Lock features a sleek black finish and a high-security Bent Foot design for enhanced protection. This lock is perfect for urban commuters, touring enthusiasts, and mountain bikers who demand reliable security during everyday rides or extended outings. Its compact, lightweight build (weighing approximately 3.15 lbs) pairs convenience with security, making transportation and storage effortless.
