Rockbros High Security U-Lock – Reliable Protection for Your Bike

Durable and Theft-Resistant
The ROCKBROS U-lock is built from 21.4mm hardened alloy steel, including a 9mm silicone cover for added protection. It features a zinc alloy C-grade lock cylinder, designed to resist leverage attacks, cutting, and drilling. With the ability to withstand up to 12 tons of cutting force, this lock provides a high level of security against theft.

Heavy-Duty Steel Cable for Added Security
This lock includes a 3.94-foot double-looped steel cable with a protective PVC coating to prevent scratches and wear. The lock comes with three rust-resistant copper keys, each designed with serpentine slots to make duplication nearly impossible. This versatile lock is suitable for securing bikes, scooters, and motorcycles in a variety of settings.

Maximum Protection Against Theft
Designed for superior security, this lock features a hardened steel body and a double-locking shackle to prevent cutting and prying. The crossbeam has undergone multiple heat treatment processes to improve its hardness and durability, making it highly resistant to forceful attacks.

Compact and Easy to Carry
With a size of 7.87 inches by 6.3 inches, this lock is compact enough to carry in a bag or attach to a bike. It includes a mounting bracket that fits circular seat posts up to 1.38 inches (35mm) in diameter, providing convenient storage while riding.

Easy Installation and Bike Protection
The included mounting bracket allows for quick and secure attachment, eliminating the need for additional carrying cases. The silicone cover not only enhances durability but also protects the bike from scratches, ensuring long-lasting use.
