Bike lock MAGNUM MGN-3013 — compact folding/security lock for bicycles

MAGNUM MGN-3013 is a compact folding/security lock for bicycles designed to secure bikes, scooters and similar personal transport. Its folding construction reduces storage size and allows practical mounting on the frame or luggage carrier. Intended for everyday urban use, this lock combines a short deployment time with a foldable rigid structure that resists casual tampering and provides reliable protection for short- to medium-duration stops.

Advantages

The lock’s folding design saves space and makes on-bike mounting convenient, while reinforced joint plates and a covered locking cylinder reduce exposure to dirt and weather. A compact folded profile fits into small bags or mounts, improving portability for commuters and casual riders. The mechanism operates with a single key for straightforward locking and unlocking, and the rigid links give better resistance to leverage and cutting attempts than soft cable locks.

Suitable for

• Securing bicycles during short urban stops and errands
• Protecting scooters and compact e-bikes in city environments
• Commuters who need a portable, frame-mounted lock option
• Users seeking a balanced solution between portability and physical security

Key specifications

• Type: folding/security lock with articulated metal links
• Construction: rigid metal plates linked by pivot joints
• Finish: protective coating over metal links to resist corrosion and prevent paint damage
• Locking mechanism: keyed cylinder with cover to reduce contamination
• Storage form: compact folded dimensions for on-bike mounting or carrying in a bag
• Intended use: urban and commuter security for short- to medium-duration stops

How to use

Open the articulated sections until the lock reaches the required length to pass through the bicycle frame and around a fixed object, then align the end with the cylinder and insert the key to engage the locking mechanism. When not in use, fold the segments back together into the compact profile and secure the lock in the provided frame mount or store it in a bag. Regularly operate the cylinder and keep the protective cover closed to minimize dirt ingress; apply a recommended lock lubricant occasionally to maintain smooth action.

Usage recommendations

For the best security results, use the lock to secure the frame and at least one wheel to an immovable object in well-lit, frequented locations. Combine this folding lock with an additional secondary lock for longer stops or higher-risk areas. Keep the key in a safe place and check the locking mechanism periodically for wear or damage.
