10 Best Kryptonite Bike Lock 2026 in the United States

The Kryptonite New York Fahgettaboutit Mini Bike U-Lock is a robust and highly secure option for those who need to protect their bicycles, e-bikes, and other valuable equipment. One of its standout features is the 18mm hardened steel shackle, which provides exceptional resistance against cutting and leverage attacks. The patented double deadbolt locking system adds an extra layer of security, making it highly resistant to common theft techniques such as twisting, picking, and drilling. Additionally, it includes a high-security disc-style cylinder for further protection.

Users will appreciate the convenience of the Key Safe Program, which allows for free replacement of lost keys, and the option to register for the Anti-Theft Protection Offer for up to $5,000 coverage. It also comes with a lifetime warranty. However, its heavy-duty design means it is not the most portable option, weighing in at 4.55 pounds. Its dimensions (9.06 x 5.98 x 1.18 inches) make it smaller and less versatile for locking up larger items. It is well-suited for high-risk areas where security is the primary concern, but the weight and size could be a drawback for those who prioritize portability.

The protective vinyl coating helps prevent damage to your bike's finish, and the black color offers a sleek, discreet appearance.

The Kryptonite Evolution Mini Bike Chain Lock is a robust option for securing your bike, motorcycle, scooter, or even gates and fences. Its heavy-duty, 10mm hardened steel chain with six-sided links offers strong resistance against cutting and leverage attacks, making it a solid choice for anti-theft protection. The lock features a patented locking system, including a high-security disc-style cylinder that resists picking and drilling, along with a reinforced oval crossbar lock head and a hardened deadbolt connection to eliminate weak points.

The 3-foot length allows for versatile locking options, though it may be a bit short for some users looking to secure both the frame and wheels together. Weighing 6.09 pounds, it’s not the lightest lock, which might affect portability for some users, but it's manageable for a chain lock of this strength. The weather-resistant nylon sleeve and durable rubber coating protect against scratches and extend the lock's lifespan, aided by a sliding dust cover for the cylinder.

Kryptonite’s Key Safe Program and optional Anti-Theft Protection Offer up to $3,000 coverage provide additional peace of mind, along with a lifetime warranty and responsive customer support. Despite its sturdy build, the lock’s weight and relatively short length could be drawbacks for those needing more flexibility and lighter options. However, for those prioritizing high security and durability, this lock is a highly reliable choice.

The Kryptonite Evolution 1012 is a heavy-duty bike chain lock designed particularly with e-bikes in mind, which often need a bit more length and strength. It features a 10mm thick hardened steel chain that’s built to resist cutting and breaking, wrapped in a weather-resistant nylon sleeve to protect your bike’s frame from scratches and to withstand outdoor conditions. The lock uses a disc-style cylinder, which Kryptonite says is highly resistant to picking and drilling, enhancing its security. It also includes a patented oval crossbar lock head and a unique end link design to avoid weak points where thieves typically attack. At about 4 feet long, it offers enough length to secure your bike to a variety of fixed objects, though its 6.8-pound weight means it’s not the most portable option for riders wanting something super lightweight.

This lock is rated 8 out of 10 for security on Kryptonite’s scale, which signifies solid protection for everyday urban use and deterrence against common theft attempts. It comes with three keys and includes a handy key replacement program if you ever lose them, plus an Anti-Theft Protection Offer that can reimburse you if your bike is stolen despite using their lock. Some users may find the chain somewhat heavy and bulky compared to lighter cable locks, so it’s best suited for those prioritizing security over portability. The combination of strong materials, thoughtful design, and added customer protections makes this lock a reliable choice for securing e-bikes, motorcycles, scooters, or even gates and fences in various weather conditions.
