Kryptonite Evolution Series U-Lock 3.25"x5.5"

The Kryptonite Evolution Series U-Lock 3.25"x5.5" is a compact, high-security lock built for urban riders who need reliable theft deterrence without the bulk. The hardened steel shackle resists cutting and leverage attacks, while the double deadbolt locking mechanism adds a second layer of protection against twist and pry attempts.

At 3.25" x 5.5", the mini footprint is sized for locking a frame to a fixed object with minimal slack — less slack means less room for a thief to work. A good choice for commuters, city cyclists, and anyone leaving a bike unattended in higher-risk areas.
