Bicycle Lock MAGNUM MGN-3025 – cable/chain lock, model 3025

MAGNUM MGN-3025 is a cable/chain bicycle lock designed to provide basic security for bicycles, scooters and other small personal vehicles. The flexible construction combines braided metal links with an outer sleeve to allow easy routing around frames and fixed objects while remaining compact enough for daily carry. Model 3025 is intended for short-term security, such as street parking, commuting stops and temporary storage.

Advantages

The cable/chain design balances flexibility and resistance, enabling convenient locking around irregular shapes and tight locations. A protective outer sheath helps prevent frame scratches and reduces exposure to moisture. The lock mechanism is simple to operate, offering quick fastening and release for frequent use. Lightweight and portable, the lock can be coiled for storage on racks, in bags or mounted with a bracket.

Suitable for

• Securing bicycles during short stops and commutes
• Locking scooters and small personal vehicles
• Temporary outdoor parking in urban environments
• Supplementary security in combination with a heavier lock

Key specifications

• Type: flexible cable/chain-style lock
• Body: braided metal links with protective outer sleeve
• Intended use: short-term security for bikes and small vehicles
• Portability: lightweight, coiling design for compact storage
• Operation: manual locking mechanism for quick fastening and release

How to use

Thread the cable/chain through the bicycle frame and one wheel, then loop it around a secure fixed object such as a bike rack or lamppost. Ensure the lock passes through parts that cannot be easily removed, and avoid relying solely on the front wheel. Insert the locking end and engage the mechanism until it clicks or confirms a secure closure. Store the coiled lock on the bike frame, in a bag or in a dedicated holder when not in use.

Usage recommendations

Use this lock primarily for short-term parking and as a secondary deterrent alongside a heavier U-lock or chain in higher-risk locations. Position the lock to limit access to the fastening point and avoid leaving the bike unattended for extended periods in high-theft areas. Regularly inspect the outer sleeve and locking mechanism for wear or damage and lubricate the lock cylinder as needed to maintain reliable operation.
