Hardened Steel Folding Chain Lock with Keys

Updated 2026-09-05

This heavy-duty folding lock features 8mm thick hardened steel links, providing a formidable defense against cutting and sawing. The 3.6ft length offers ample reach for securing e-bikes, motorcycles, or mountain bikes to various fixed objects. Its folding design allows the rigid steel sections to collapse into a compact shape for easy transport on the frame.

The lock comes with four keys, ensuring you have plenty of spares for multiple users or backup locations. The keyed cylinder is designed for high security, resisting picking and drilling attempts. The robust construction is specifically tailored for high-value vehicles like ebikes and MTB, where a higher level of physical protection is required for long-term parking.

A protective coating on the steel links prevents metal-on-metal contact, keeping your bike's paint job pristine. The joints are reinforced to withstand leverage attacks, while still allowing for smooth folding and unfolding. This lock combines the security of a chain with the organized storage of a folding tool, making it a top choice for serious security.
