Bicycle lock MAGNUM MGN-3107 — cable/chain lock model 3107

MAGNUM MGN-3107 — cable/chain lock model 3107 is a compact security lock designed for daily bicycle protection. The combined cable and chain-style construction provides flexibility when securing a bike to posts, racks or other fixed objects. Its portable form factor makes it suitable for commuting, short stops and general urban use where moderate theft deterrence is required.

Advantages

The MAGNUM MGN-3107 combines the flexibility of a cable with the increased cut resistance of a short chain section, allowing easier routing through frames and wheels while maintaining a higher level of security than a plain cable. Its light weight and compact size enable convenient carrying on rides or in a bag. The locking mechanism is designed for straightforward operation, providing reliable closure and a predictable user experience.

Suitable for

• Commuting and urban cycling where portability is important
• Short stops at shops, cafés or public transport hubs
• Securing bicycles to stands, poles and fixed racks
• Use by cyclists who need a balance between convenience and basic theft deterrence

Key specifications

• Lock type: combined cable and chain-style bicycle lock
• Design: compact and portable with flexible routing
• Security features: chain-reinforced section for improved cut resistance compared to cable-only locks
• Operation: mechanical keyed lock mechanism for straightforward use
• Intended use: everyday urban and commuter bicycle security

How to use

Pass the cable/chain through the bicycle frame and at least one wheel, then loop it around a fixed, immovable object before closing the keyed lock. Position the chain-reinforced section where maximum resistance to cutting is required and avoid leaving the lock on the ground to limit exposure to moisture and grit. Keep the key in a safe place and consider carrying a spare key when possible.

Usage recommendations

For improved security, lock the frame and both wheels when possible and choose well-lit, busy parking locations. Use the MAGNUM MGN-3107 together with a secondary security measure (such as a U-lock or alarm) for longer stops or in high-risk areas. Regularly inspect the lock for wear and lubricate the key mechanism occasionally to maintain smooth operation.
