The DUNLOP Bicycle Chain Lock 120 cm is a steel chain with an integrated keyed lock designed to secure bicycles, frames and wheels. With a length of 120 cm, this chain provides flexible anchoring options to fixed objects such as bike racks, poles and fences. The lock is intended for everyday urban use, offering practical protection for commuting and short-term parking while remaining compact enough for carrying in a bag or fitting to a frame with a mounting bracket.
Advantages
The steel construction delivers robust resistance against casual cutting and sawing attempts, while the integrated keyed cylinder ensures straightforward locking and unlocking. At 120 cm long, the chain balances portability with reach, allowing you to secure both frame and wheel when space and anchor points vary. The design is suitable for frequent daily use and easy transport, making it a practical choice for riders who need a reliable, no-nonsense security solution.

How to use
Wrap the chain around a secure, immovable object and pass it through the bicycle frame and, where possible, a wheel to minimise the risk of theft. Insert the chain end into the lock body and turn the key to engage the cylinder; remove the key after locking. When unlocking, insert the key and rotate to release the cylinder, then remove the chain from the anchor. Store the key in a safe place and inspect the chain and lock regularly for signs of wear or damage.
Usage recommendations
For better security, use the chain to secure both the frame and at least one wheel to an immovable object and select well-lit, visible parking locations. Avoid fastening the bike to objects that can be easily lifted or dismantled. Keep a spare key in a secure location and check the lock periodically for corrosion or mechanical wear.
