LIHAO Disc Lock Bike Anti-Theft Immobilizer Hardened Steel 110dB Alarm

Description

Product Overview

The LIHAO Disc Lock is engineered for cyclists who demand uncompromising security without the bulk of traditional U‑locks. Constructed from hardened steel, the lock resists cutting and lever attacks, while an integrated microprocessor monitors shock and motion. When tampering is detected, a 110dB alarm sounds, alerting the rider and deterring thieves. The lock measures 7.2 x 4.69 x 1.65 inches and weighs just 11.3 ounces, making it lightweight enough to carry in a backpack or attach to a bike frame.

Usage

Designed for everyday commuters, mountain bikers, and powersports enthusiasts, this disc lock fits most standard disc brake rotors. Secure the lock to a sturdy object such as a bike rack, post, or frame tube, then engage the self‑arming mechanism. The lock automatically re‑arms within 15 seconds after an attempted attack stops, ensuring continuous protection. Its compact size means you can store it in a saddlebag, backpack, or even a pocket, providing peace of mind wherever you ride.
