Bicycle chain lock DUNLOP 120 cm length steel chain with key, model 1042862

DUNLOP 120 cm bicycle chain lock combines a steel linked chain with an integrated keyed locking mechanism to secure bicycles during everyday parking and short-term outdoor storage. The 120 cm length allows the chain to wrap around most frames and wheels and attach to fixed objects such as bike racks, poles or railings. The lock is intended for urban and commuting use where a portable, cable-free security solution is required.

Advantages

The steel chain construction provides robust resistance to casual cutting attempts compared with thin cables while remaining flexible enough for convenient carrying and fastening. The keyed lock mechanism offers simple operation and reliable closure without the need for electronic components or batteries. The length and link size are balanced to allow versatile securing options for frames, wheels and accessories while keeping overall weight manageable for daily use.

Suitable for

• Securing adult and children’s bicycles during short-term urban parking
• Commuter riders leaving a bike at a workplace bike rack
• Attaching frame and rear wheel to fixed objects to deter quick theft
• Everyday use where a portable, mechanical lock is preferred over electronic solutions

Key specifications

• Chain length: 120 cm
• Material: steel linked chain
• Lock type: mechanical keyed locking mechanism
• Design: flexible linked segments for wrapping around frames and objects
• Intended use: outdoor bicycle security for short-term parking and commuting

How to use

Pass the chain through the bicycle frame and, if desired, one or both wheels, then loop the chain around a secure fixed object such as a bike rack or pole. Insert the lock end into the keyed mechanism and turn the key to engage the lock. Keep the spare key in a safe place and carry the primary key or a compact key holder while riding. When unlocking, insert the key and turn to release, then pass the chain free from the secured object.

Usage recommendations

For improved security, position the chain to include the frame and rear wheel and use the shortest practical loop around a fixed object to reduce exposed chain length. Avoid leaving the bicycle locked in isolated or poorly lit areas for extended periods. Store the chain lock under cover when not in use to reduce corrosion risk and inspect the keyed mechanism periodically for debris or wear.
