Bicycle Lock Anti-Theft Folding Burger Lock with Zinc Alloy Body and Hardened Steel Joints

Secure your bicycle with a lock that combines practical design with robust materials. This folding burger lock features a zinc alloy lock body and 3mm hardened steel joints at four chain blocks, providing reliable anti-theft protection. The ABS case prevents scratches on your bike frame, and the drilled cylinder design adds an extra layer of security. Measuring 585mm x 70mm x 50mm, it is compact enough for everyday commuting or locking up your bike when visiting friends. The set includes three keys and a quick-release locker for easy mounting.
Features and Construction

This lock is built around a folding hamburger-shaped design that stores neatly and deploys quickly. The zinc alloy and ABS construction balances strength with a practical weight, while the hardened steel joints reinforce the chain links.
Material and Build
The lock body is made from zinc alloy with an ABS outer case to avoid scratching your bicycle paintwork. The keys are high-grade steel. The design injects 3 mm hardened steel into each joint of the four chain blocks, giving the folding sections extra strength against cutting attempts.
Size and Practical Fit
At 585mm total length, 70mm width, and 50mm height, this lock is suitable for securing the frame and one wheel to a fixed post or cycle rack. The folding shape means it does not take up excessive bag space or rattle against the frame when properly mounted using the included locker and retainer seal.
Uses and Placement

Whether you lock up your bike at a station, outside a shop, or at home, this lock offers a practical solution. The ABS case keeps the lock from scratching your frame during transport, and the quick-release locker allows for simple mounting and removal.
Event or Professional Use
For commuters who lock their bike in the same location daily, the folding design saves time and reduces bag clutter. The included hex wrench and plastic screws let you install the locker permanently on the seat stay or down tube, so the lock is always ready to use.
Everyday Home Use
Use the lock to secure garden bikes, children's cycles, or scooters. The three keys mean you can leave one at home, one with a partner, and carry one with you. The drilled cylinder adds resistance against picking, making it a sensible choice for low to medium risk environments.
Benefits and Buying Value

This lock offers a balance of security and convenience. The materials are chosen to resist cutting and picking, while the folding shape and ABS case make day-to-day use easier. The package includes all necessary mounting hardware.
Reuse and Low Maintenance
The zinc alloy and steel construction requires minimal care. Wipe the lock dry after wet rides to prevent corrosion. The drilled cylinder should be lubricated occasionally with a light oil if it becomes stiff. The three spare keys mean you are unlikely to be locked out.
Why Choose This Product
If you want a lock that is easier to carry than a heavy chain yet offers the same folding convenience, this burger design is a direct solution. The 3mm hardened steel joints are a concrete differentiator from simpler folding locks. The ABS case shows attention to frame care, adding everyday longevity to your bike's finish.
