Heavy duty folding bike lock with keys

Engineered for high-level security, this folding lock provides a robust physical barrier against theft. The design features multiple articulated steel plates that fold into a compact shape for transport but extend to a generous 47 in length. This extra length makes it much easier to secure a bicycle to larger fixed objects like lamp posts.

The folding mechanism is built to be both flexible and strong, offering the security of a U-lock with the versatility of a chain. Each joint is reinforced to resist cutting and prying attempts, making it a reliable choice for high-risk urban areas. The keyed entry system is precise, ensuring smooth operation every time the lock is engaged.

Designed for durability in outdoor environments, the materials are treated to resist corrosion and wear from the elements. The lock comes with two keys, providing a convenient backup in case one is misplaced. Its unique folding design allows it to be stored in a relatively small space on the bike frame when not in use.
