Kryptonite Evolution 1012 Bike Chain Lock - Heavy Duty Security

Our review of the Kryptonite Evolution 1012 finds it best for riders who need a robust, no-nonsense chain lock for heavier bikes and e-bikes. The single biggest reason to buy is the high-security construction: 10mm hardened steel links with a patented reinforced crossbar and a disc-style cylinder that resists picking and drilling, which gives clear protection where lighter locks fail. It is noticeably heavy, but that weight is the tradeoff for a chain designed to deter determined thieves and secure larger, more valuable bikes.

Key Features

• 10mm hardened steel chain: Thick six-sided links provide strong resistance to cutting and leverage attacks for improved bike security.
• Patented reinforced oval crossbar: The integrated lock head reduces weak points and increases overall chain durability.
• High-security disc-style cylinder: The lock cylinder is resistant to picking and drilling, extending real-world protection.
• Weather-resistant nylon sleeve: A durable sleeve prevents paint damage and protects the chain from the elements.
• Sliding dustcover and keys: A sliding dustcover extends cylinder life and the lock ships with three keys, with key replacement options available.
• Extended length for e-bikes: At roughly 4 ft in length, it offers the extra reach needed to secure larger frames and wheels.

Who It's For

The Evolution 1012 is aimed at commuters and e-bike owners who need a substantially stronger chain than the lighter U-locks and cable locks offer. If you routinely park in higher-theft areas or need to secure a heavier e-bike or motorcycle, the robust construction and length make this a practical choice.

It is less suitable for riders who prioritize minimal weight or compact transport on long rides, since the chain is noticeably heavy. Casual riders seeking a lightweight, portable option should consider a lighter lock instead.
