Bicycle Chain Lock DUNLOP 900 cm - combination lock, green

The DUNLOP bicycle chain lock 900 cm is a flexible security solution designed to secure bicycles, scooters and similar vehicles. With a 9-metre length and a combination locking mechanism, the chain can wrap around frames, poles or other fixed objects to provide adaptable protection in urban environments, short-term parking and everyday commuting. The green finish makes the lock visible and easy to locate while the combination system removes the need for carrying a key.

Advantages

The long, flexible chain allows a wide range of locking positions and can secure multiple items at once or reach distant anchor points. The combination mechanism offers keyless convenience and adjustable codes for repeated use. The chain’s protective coating helps prevent frame scratches and reduces wear on painted surfaces. Its length and flexibility make it practical for cyclists who need to secure bikes in varying urban settings.

Suitable for

• Securing bicycles and scooters in city streets and parks
• Short-term parking outside shops, schools or public transport hubs
• Locking multiple bikes or additional accessories together
• Everyday commuting where a long, adaptable locking solution is helpful

Key specifications

• Length: 900 cm (9 metres)
• Locking type: combination lock (keyless)
• Finish: green protective coating
• Application: external use for bicycles, scooters and similar vehicles
• Design: flexible chain for wrapping around frames and fixed objects

How to use

Wrap the chain around the bicycle frame and a secure anchor point such as a pole or rack, ensuring the chain passes through the frame and ideally the wheel to reduce theft risk. Align the two ends of the combination lock and set the code according to the manufacturer’s instructions, then scramble the digits to lock. Check that the coated chain does not pinch paint and that the connection is secure before leaving the bike. To open, align the correct combination and separate the two locking ends.

Usage recommendations

For improved security, use the DUNLOP chain lock together with a secondary lock or secure the frame and one wheel. Avoid leaving the same combination code visible or obvious, and store the combination in a safe place. Regularly inspect the chain coating and locking mechanism for signs of wear and clean the lock if exposed to heavy dirt or moisture.
