Stainless steel heavy duty alarm lock

Updated 2026-09-05

Constructed from high-grade stainless steel, this u-lock is specifically engineered to resist corrosion and environmental wear. The 12mm shackle provides a robust physical barrier, while the upgraded 130dB alarm system adds an electronic layer of defense. It is designed for cyclists who park in exposed outdoor locations where weather resistance is a priority.

The internal alarm sensors are calibrated to detect vibrations and movement, sounding a loud alert to startle thieves and notify bystanders. Its stainless steel body ensures that the locking mechanism remains fluid and functional even after prolonged exposure to rain and humidity. This makes it a dependable choice for year-round outdoor security.

The compact u-lock design is easy to transport while offering enough internal clearance to secure most bicycle frames to standard racks. The keyed entry system is reinforced against common tampering methods. This model balances physical strength with advanced electronic security features to protect e-bikes and standard bicycles from sophisticated theft attempts.
