FISCHER Bicycle Chain Lock model 85860, 900 mm length, 24 mm diameter, black, steel cable

FISCHER Bicycle Chain Lock model 85860 is a hybrid security solution combining a linked chain and a heavy-duty steel cable with a protective sleeve. Measuring 900 mm in length and covered by a 24 mm diameter black protective sheath, the lock is intended to secure bicycles to fixed objects such as racks, posts or railings. The construction focuses on practical everyday use for urban commuters, storage and short-term parking where a balance of portability and visible deterrence is required.

Advantages

The lock integrates a linked chain with an extremely robust steel cable to provide flexible reach and resistance to torsion. The 24 mm diameter protective cover reduces cosmetic damage to frames and shields the metal core from weather exposure. At 900 mm length the lock is compact enough for daily transport yet long enough to loop through frames and wheels and secure to many standard anchor points. The black finish offers a discreet appearance suitable for different bike styles and environments.

Suitable for

• Commuter bicycles used for short-term parking in urban areas
• Securing a bicycle to fixed street furniture, bike racks or posts
• Situations requiring a balance between portability and visible deterrence

When it may not be suitable

This lock is designed for on-street protection and short-term security; it is not intended to provide the highest level of protection against persistent, professional theft attempts. Users seeking maximum security for long-term outdoor parking in high-risk areas may prefer heavier duty locks or a combination of locking systems.

Key specifications

• Length: 900 mm
• Protective cover diameter: 24 mm
• Material: linked chain with steel cable core and protective sleeve
• Color: black

How to use

Thread the chain lock through the bicycle frame and, if possible, through at least one wheel before looping it around a secure fixed object. Pull the steel cable taut and fasten according to the lock mechanism supplied. Position the protective sleeve so it rests between metal parts to avoid scratching the bike frame. Store the lock safely when not in use to avoid exposure to prolonged moisture.

What to consider before purchase

• Required length to reach your typical anchor points
• Desired balance between portability and security level
• Whether additional locks are needed for long-term or high-risk parking
• Compatibility with your bicycle frame and wheel layout

Usage recommendations

Use the lock in combination with a fixed, immovable object and, where possible, secure both frame and at least one wheel. For higher-risk locations, consider pairing this chain lock with a secondary lock for added security.
