Durable Anti-Theft Bicycle Lock with 2 Keys

Unlocking Flexibility

NDAKTER Bike Chain Locks offer you two effortless unlocking methods. You can open the lock using either the 2 keys or a 4-digit resettable code. If you forget the code, you can always use the keys, or vice versa. The default password is "0000," which you can easily change to your own code.

Robust Protection and Portability

These heavy-duty anti-theft bike locks are crafted with a Zinc alloy lock cylinder and a sturdy 0.24-inch/6mm alloy steel chain. This robust material ensures durability, making the lock wear-resistant, rust-proof, and cut-resistant. The lock weighs only about 1.94 pounds, which is much lighter than traditional U-locks, making it easy to carry and flexible to use.

Scratch- and Clank-Resistant

The combination lock is wrapped in high-quality polypropylene fabric, providing protection and preventing scratches on your bike frame. Enjoy a quiet ride without loud clunking noises. The lock is available in various colors, so you can choose one that matches your bike or adds a personal touch.

Easy and Convenient Reset

Resetting your lock is a breeze: 1. Use the default password "0000." 2. Turn the knob 90 degrees forward from the default position. 3. Adjust the digital code to your desired password. 4. Return the knob to the default position. 5. Dial back your new password and insert the lock tongue to complete the process. (Please remember your new password and consider taking photos for reference.)

Versatile Applications

The 3.2-foot-long chain is ideal for protecting multiple bikes or securing your bike to trees, gates, fences, railings, thick poles, and more. The lock also finds versatile use with motorcycles, scooters, skateboards, grill, ladders, doors, lawnmowers, and many other items. While the lock provides excellent protection, it's important to remember that no bike lock is 100% secure. Always be cautious and avoid leaving your bike unattended in high-crime areas.
