Kryptonite 1090 High Security Bicycle Chain Lock – Series 4

Product Description:

Navigating city streets demands more than just speed—it requires trust in your bike’s safety. The Kryptonite Evolution Chain Lock is engineered for urban cyclists who prioritize both security and adaptability during long-term parkings in bustling metro areas. Crafted with a robust manganese steel core encased in a protective fabric sleeve, this lock offers unmatched flexibility to wrap around diverse objects like thick poles, railings, or even irregularly shaped fixtures where traditional U-locks fall short. Its lightweight yet sturdy design ensures you can secure your ride confidently without straining your commute—perfect for daily use or extended parking sessions in high-traffic zones.

At just 6.1 pounds and 90 inches long, this key-operated chain lock strikes an ideal balance between portability and coverage, making it easy to carry while still accommodating larger locking scenarios. The 10mm diameter chain resists cutting and prying attempts, backed by Kryptonite’s reputation for anti-theft innovation. The fabric coating not only shields surfaces from scratches but also provides a comfortable grip during setup, even in cold weather conditions.

Whether you’re locking up at a crowded transit hub, securing your bike overnight at a city garage, or needing reliable protection for e-bikes and heavier models in urban environments—the Evolution series delivers peace of mind without compromising on practicality. Designed for riders who value versatility and long-term durability, this lock adapts seamlessly to unpredictable parking situations while maintaining its status as one of the most trusted names in metro-area bike security solutions.
