An innovative U-lock equipped with a gyroscope-based motion-sensitive alarm system
that screeches at 120 decibels for 10 seconds whenever the lock is moved or tampered with.
To lock and activate alarm, simply turn the key once.
To lock without activating the alarm, turn the key twice within 5 seconds.
Multi-layered barrel design shields the battery and electronics
from the elements.
High Carbon Steel
Carbon steel tamper-resistant build, with a 2-layer coating that
provides extra protection against rust, weathering corrosion.
Secure Battery Compartment
The battery compartment holds a single CR2 battery that will
power the alarm system for 10 months, and is only accessible with the key.
