Folding hardened steel portable bicycle lock

Updated 2026-09-05

This folding lock offers a unique combination of high-strength security and compact portability for urban cyclists. By utilizing a series of interconnected steel plates, the device can extend to secure a frame and then fold down into a small footprint for transport. This design is particularly beneficial for riders who prefer a sleek look.

The 8mm hardened steel links are engineered to withstand various physical attacks, including cutting and shearing. Each joint is designed to be flexible yet robust, allowing the lock to navigate around tight spaces and different frame geometries. The high-quality cylinder provides reliable protection against picking, ensuring that the bicycle remains exactly where it was left.

Included with the lock is a dedicated transport bracket that easily mounts to the bicycle frame, allowing for rattle-free storage during transit. The links are coated with a soft plastic material to prevent any damage to the bike's paintwork. This model is ideal for commuters who need a dependable security tool that is easy to carry.
