Anweller Fingerprint Bike Chain Lock — 1M Heavy-Duty Φ8mm Steel Chain, Biometric Unlock & IP67 Weatherproof

The Anweller Fingerprint Bike Chain Lock is a heavy-duty, 1M chain lock with biometric unlocking, app control, and weatherproof protection for secure everyday bike security.

Whether you commute, run errands, or park a prized ride outdoors, this smart chain lock combines a thick, cut-resistant steel chain with a fast fingerprint sensor and Bluetooth app management. It replaces keys and codes with biometric access, records unlocking events, and is built to withstand rain, snow, and corrosive conditions. The compact unit also offers long battery life and USB-C charging so it stays ready without frequent maintenance.

How robust is the chain against physical attack?

The lock uses a 0.31" (approximately Φ8 mm) hardened steel chain designed to resist bolt cutters and common cutting tools, with a protective sleeve to prevent frame scratches. The short 1 m (3.3 ft) length lets you secure a frame and wheel to many fixed objects while minimizing exposed chain that thieves could exploit.

• Thick Φ0.31 steel links for higher cut resistance
• 1 m / 3.3 ft length for versatile locking points
• Durable outer cover to protect paint and reduce tampering

How fast and reliable is the fingerprint unlocking?

The built-in biometric sensor uses self-learning AI to recognize registered prints and unlock almost instantly—typically within fractions of a second—so you can release your bike quickly without fumbling for keys. The reader is shielded by a cover to keep moisture and debris off the sensor and maintain consistent performance outdoors.

• AI-enhanced fingerprint recognition for faster, more accurate access
• Protected sensor housing for reliable outdoor use
• No keys or passcodes required—fingerprint is the primary key

What smart controls and tracking does the lock include?

Connect via Bluetooth to the Anweller mobile app to add or remove fingerprints, view recent unlock logs, and manage shared access. The app also supports unlocking from an Apple Watch, which is convenient for hands-free access when you're on the move.

• App-based user and fingerprint management
• Unlock history and access control monitoring
• Apple Watch unlock for quick hands-free release

Can it handle outdoor conditions and what about battery life?

Designed to meet IP67 standards, the lock resists water, dust, rust, and corrosion so it continues working through wet or dusty environments. A 330 mAh Li-ion battery provides long standby time—rated for thousands of unlocks—and fast USB-C recharging keeps downtime minimal.

• IP67-rated weatherproofing for outdoor durability
• 330 mAh battery with roughly 3000 unlocks per charge
• Fast Type-C charging—full recharge in about 2 hours

It suits riders who value quick, keyless access, app-based access control, and a weatherproof design that requires minimal upkeep. If you need a heavy-duty chain lock that adds biometric and smart features without sacrificing durability, this model is a solid choice.
