DUNLOP bicycle chain lock with key, length 120 cm, model 1042855

The DUNLOP bicycle chain lock with key, length 120 cm, model 1042855 is a compact security accessory designed for everyday urban cycling and short-term parking. The lock combines a hardened metal chain with an integrated cylinder and key, allowing the chain to be looped around the bicycle frame and a fixed object such as a post or rack. Its 120 cm length provides enough reach for typical city parking situations while remaining portable for storage on a rack or in a bag.

Advantages

This chain lock offers straightforward mechanical operation with a keyed cylinder for reliable closing and opening. The hardened links increase resistance to casual cutting attempts and the mid-length chain balances security and convenience for daily commuters. The integrated locking mechanism reduces the number of separate parts to carry, and the compact package makes it suitable for placement on a rear rack or carried in a pannier or backpack.

Suitable for

• Securing city bicycles during short-term stops
• Locking commuter e-bikes on sidewalks and public racks
• Everyday urban cycling and public transport interchanges
• Temporary locking of kids’ ride-on bikes and scooters

Key specifications

• Chain length: 120 cm
• Lock type: keyed cylinder with integrated mechanism

How to use

Thread the chain through the bicycle frame and around an immovable object such as a dedicated bike rack or sturdy post, then insert the chain end into the integrated locking cylinder and turn the key to secure. Keep the key in a safe place and avoid forcing the cylinder; apply gentle, steady pressure when locking and unlocking. Inspect the chain periodically for signs of wear or corrosion and store the lock in a dry place when not in use.

Usage recommendations

For improved security, loop the chain through the rear triangle of the frame and a wheel where possible, and choose well-lit, visible parking locations. Use the lock in combination with additional deterrents if leaving the bike unattended for extended periods.
