Heavy Duty 4 Digit Anti-Theft Bike Lock with 2 Keys (Grey)

All The Must-Know Details

Unlock in Two Ways

NDAKTER bike chain locks offer two easy unlocking methods to fit your needs. You can use 2 keys or a 4-digit resettable code. If you forget the code, you can simply use the keys, and vice versa. The default code is "0000," which you can easily change to your own.

Strong and Reliable Protection

Crafted from zinc alloy and 0.24 inch/6mm steel, these locks are incredibly durable. They are wear-resistant, rust-proof, and resistant to cutting. The lock weighs about 1.94 pounds—lighter than a U-Lock, making it easy to carry. The flexible chain allows you to wrap it around various objects.

Scratch-Resistant and Elegant

The combination lock is wrapped in high-quality polypropylene fabric, providing protection and preventing scratches on your bike frame. It's quiet during use and won't make loud clinking noises. Available in multiple colors, you can choose a lock that matches your bike.

Easy to Reset

1. Open the lock using the default password "0000".
2. Turn the knob forward 90 degrees from the default position.
3. Set your new password by turning the digital dial.
4. Return the knob to the default position.
5. Dial back your new password and insert the locking tongue to complete.

Wide Application

With a length of 3.2 feet and a weight of about 1.59 pounds, these locks are versatile. They can lock up to 3-4 bikes together or secure your bike to a tree, gate, fence, railing, or thick pole. They are also suitable for motorcycles, scooters, skateboards, grills, ladders, doors, lawnmowers, and many other items. Just remember, while this lock enhances security, no bike lock is 100% secure. Keep your bike out of high-crime areas whenever possible.
