Everything Important At A Glance

Secure & Resettable 5-Digit Combination Bike Chain Lock

SAFER THAN EVER: Unlike 4-digit locks, our 5-digit resettable combination bike chain lock boasts enhanced security with a harder-to-guess code. Set your personalized number combination with ease to ensure your bicycle is protected.

Sturdy & Durable

DRILL-RESISTANT AND DURABLE MATERIALS: Constructed from zinc alloy for the lock cylinder and 0.16-inch alloy steel for the bicycle chain, our lock is highly resistant to drill damage and anti-tech unlocking. While no single lock is 128% safe, taking extra precautions, such as not leaving your bike unattended in high crime areas, is advised.

Scratch-Proof Fabric Protection

SAFETY AND COMFORT: The bicycle chain lock is encased in a high-quality polypropylene fabric, which is scratch-proof, wear-resistant, and secure from hot and cold temperatures. This ensures the chain remains intact and prevents damage to your bicycle frame, extending the product’s lifespan.

Convenient to Use

KEYLESS CONVENIENCE: Our combination locking mechanism ensures keyless access to your bike with easy-to-follow steps. Forget about losing your key or forgetting to carry it. The password can be reset, offering 10,000 possible combinations, making it incredibly difficult for anyone to guess. The default code is set to 00028.

Multi-Purpose

FLEXIBLE AND ADAPTABLE: Our chain lock measures 2.62 feet in length and weighs about 0.71 pounds, making it ideal for locking multiple bikes together or securing your bike to trees, gates, fences, railings, and other objects. It is versatile enough for motorcycles, scooters, skateboards, grills, ladders, doors, and lawnmowers.

Multi-Purpose Usage

ADAPTIVE SECURITY: The lock head's diameter is approximately 1.25 inches/3.2 cm, suitable for nearly all bike wheel sizes currently on the market. However, for scooters, e-bikes, or any vehicle with a wheel gap or hole smaller than 1.25 inches/3.2 cm, you may wrap the lock around the object rather than passing it through the wheel. Always double-check the fit to ensure maximum security.

Reminder

Please note: The lock head's diameter is approximately 1.25 inches/3.2 cm, meeting the security demands of most bike wheels on sale today. If your scooter, e-bike, or other vehicle has a wheel gap or hole smaller than this size, we recommend wrapping the lock around the object rather than passing it through the wheel to ensure proper security.
