Ultimate Protection for Your Bike: Kryptonite Maximum Security U-Lock

Keep thieves at bay with Kryptonite’s toughest U-lock, engineered for cyclists who demand uncompromising security. Built with 16mm Kryptonium steel and a double deadbolt mechanism, this lock resists cutting, prying, and leverage attacks—ideal for high-theft urban areas or leaving your bike unattended for extended periods.

Key Features:

• Military-Grade Security: 16mm hardened steel shackle with an oversized crossbar sleeve for reinforced defense against bolt cutters and saws.
• Triple-Key Convenience: Includes two standard keys and an LED-lighted key for effortless nighttime access.
• Compact Yet Durable: 8″ length provides a snug fit around bike frames and racks without sacrificing portability (advertised weight: 4.35 lbs).

Why Choose This Lock?

Unlike thinner shackle locks vulnerable to angle grinders, this model’s 4″ wide shackle and double-locking bolts add critical seconds to a thief’s effort—often deterring theft altogether. Perfect for commuters, e-bike owners, or anyone securing high-value bikes in risky neighborhoods.

Dimensions: 16mm diameter | 8″ length | No included cable (pair with a chain for added flexibility).

Upgrade to peace of mind—because your bike deserves the best defense.
