Heavy Duty 5 Digit Combination Bike Chain Lock, Anti-Theft Security Lock

The Core Capabilities Of This Product

SECURE & RESETTABLE: Our bike chain lock features a 5-digit resettable combination, making it safer than standard 4-digit locks. Set your own personalized number combination easily.

STURDY & DURABLE: The lock cylinder is made of zinc alloy, making it hard to break through. The alloy steel chain, 0.16 inches thick, is drill-resistant and anti-tech unlocking. Safety tip: Don't leave your bike unattended for too long, especially in high-crime areas. No bike lock is 100% safe.

SCRATCH-PROOF FABRIC PROTECTION: Wrapped in high-quality polypropylene fabric, this lock is scratch-proof and wear-resistant. The fabric also provides anti-hot and anti-icing hand protection, and prevents scratching your bicycle frame. This ensures a long lifespan.

CONVENIENT TO USE: The combination locking mechanism offers keyless convenience. Easily set your own password through simple steps. With keyless convenience, you don’t have to worry about losing or carrying a key. The code is resettable, with 10,000 possible combinations. The default code is 00028. The lock is easy to use and save you the hassle of carrying keys.

MULTI-PURPOSE: The 2.62-foot-long chain and 0.71-pound weight make it perfect for locking 1-2 bikes together or securing to a tree, gate, fence, railing, thick pole, or other objects. It can also be used for motorcycles, scooters, skateboards, grills, ladders, doors, lawnmowers, and many more.

KINDLY REMINDER: The lock head's diameter is approximately 1.25 inches/3.2 cm, meeting the security needs of most bike wheels. However, if your scooter or e-bike has a wheel gap or hole less than 1.25 inches/3.2 cm, the lock may not fit through the wheel. In such cases, we recommend wrapping the lock around the scooter rather than passing it through the wheel gap.
