Chain lock ABUS 57658 Yellow 600 mm Steel 230 g 4 mm diameter

The ABUS 57658 Yellow 600 mm chain lock is a compact steel security solution designed for everyday bicycle protection. Constructed from hardened steel links with a 4 mm diameter and a total length of 600 mm, this lightweight lock weighs approximately 230 g and is supplied with two keys. Its bright yellow coating improves visibility and helps prevent scratches to frame paint while keeping the chain resistant to corrosion.

Advantages

The chain combines compact dimensions and low weight with hardened-steel construction to provide a balance of portability and basic theft deterrence. The 4 mm links and steel body offer mechanical resistance to casual attacks, while the protective coating reduces wear on contact surfaces. Supplied keys provide straightforward locking and unlocking without electronic components, ensuring simple operation and low maintenance.

Suitable for

• Securing bicycles in low- to medium-risk urban environments
• Locking scooters, luggage or accessories during short stops
• Use as a secondary lock in combination with a U-lock or frame lock

Key specifications

• Material: steel links with protective yellow coating
• Chain length: 600 mm
• Link diameter: 4 mm
• Weight: approximately 230 g
• Closure: mechanical cylinder lock with two supplied keys

How to use

Wrap the chain around the bicycle frame and a fixed object such as a bike rack or pole, ensuring the chain passes through the frame and, where possible, the rear wheel. Insert the chain end into the lock cylinder and turn the key to secure; remove the key after locking. To unlock, insert the key, turn to release the cylinder and remove the chain. Keep the chain and key dry and free of grit to maintain smooth operation.

Usage recommendations

For improved security, position the chain so it is tight around the frame and object, minimizing leverage for cutting tools. Use this chain in combination with a higher-security lock in high-risk areas. Store the lock indoors when not in use to reduce corrosion and periodically lubricate the cylinder with a light graphite or silicone-based lubricant if stiffness occurs.
