Folding Combination Bike Chain Lock for Anti-Theft Security

Secure, Foldable Protection for Bikes, E‑Bikes and Motorcycles

This folding combination chain lock is designed for riders who need reliable, everyday security for bicycles, electric bikes and motorcycles. Built from hardened metal alloys with a compact, articulated design, it delivers strong resistance to cutting and tampering while folding down for easy transport. The resettable combination mechanism removes the need for keys, making it a practical solution for commuting, city riding and long-distance trips.

The lock uses an innovative super-connection system between each segment, creating tight, reinforced joints that are stronger than many conventional folding locks. Its 8 mm thick lock plates extend to approximately 1200 mm, giving enough length to secure the frame and wheel to fixed objects such as racks, posts or railings. When not in use, the lock folds into a compact block that mounts neatly to your frame using the included side bracket, cable ties and screws.

Constructed from a mix of zinc alloy, 304 stainless steel and durable ABS/PA6 plastics, this lock balances strength with protection for your bike's finish. The rigid metal core resists cutting, sawing and leverage attacks, while the outer plastic housings help prevent scratches on frames and components. It is suitable for mountain bikes, road bikes, folding bikes, scooters, e‑bikes and small motorcycles, offering a single solution for multiple two‑wheeled vehicles.

The 4-digit combination system arrives preset to 0000 and can be reprogrammed to a personal code, reducing the risk of lost keys and simplifying daily use. Clear, easy-to-read digits support quick locking and unlocking, even in low light. With eight folding sections, robust joints and a practical mounting system, this lock is designed to integrate into your regular riding routine without adding unnecessary bulk.
