Hardened alloy steel small U lock

Updated 2026-09-05

This compact U-lock is built for high-security applications, featuring a massive 18mm hardened alloy steel shackle. The thick diameter is specifically designed to resist bolt cutters and prying attempts, making it a formidable choice for protecting high-value assets like motorcycles, e-bikes, and utility trailers in outdoor environments.

The lock comes equipped with four specialized keys, providing plenty of spares for multiple users or backup storage. The internal cylinder is engineered to be pick-resistant, adding another layer of defense against sophisticated theft attempts. Its small form factor allows it to be used in tight spaces where larger locks might not fit.

Constructed to endure the elements, the lock body and shackle are treated to resist corrosion and rust. The heavy-duty materials ensure that the lock remains functional and secure even when subjected to harsh weather conditions, providing consistent protection for your vehicle or equipment throughout the year.
