DUNLOP Chain Bike Lock with Combination, Yellow - Dunlop model 5907731989152

The DUNLOP Chain Bike Lock with Combination in yellow is a compact, keyless security accessory designed for everyday urban use and short-term parking. It features a flexible steel chain enclosed in a protective fabric sleeve to reduce the risk of paint damage and surface scratches. The lock uses a user-set numeric combination, making it suitable for children’s bikes, scooters, school environments and quick stops where a lightweight, easy-to-operate solution is preferred.

Advantages

This chain lock provides the convenience of keyless operation through a numeric combination that can be reset to a personal code. The protective sleeve shields the bicycle frame from abrasion and marks while the flexible chain allows easier attachment to fixed objects in constrained spaces. Its compact length and moderate weight make it simple to carry or store on a child’s bike without significant burden.

Suitable for (tasks / use cases)

• Securing children’s bicycles and scooters for short periods
• Everyday urban use for quick stops, errands or school drop-offs
• Temporary locking in low-risk areas such as parks, playgrounds or indoor bike racks
• Situations where keyless, easy-to-reset locking is preferred

When it may not be suitable

This chain lock is intended for low- to moderate-risk situations and short-term parking. It may not provide adequate protection in high-theft areas or for long-term outdoor storage where heavier, hardened steel U-locks or longer heavy-duty chains with high-security locks are recommended. Users seeking maximum theft resistance should opt for a certified high-security locking solution.

Key specifications

• Lock type: Chain lock with numeric combination
• Chain construction: Flexible steel links
• Protective covering: Fabric sleeve to prevent frame scratching
• Operation: User-set numeric code (keyless)
• Color: Yellow

How to use

Wrap the chain around the bicycle frame and a secure fixed object, ensuring the chain passes through the frame or wheel as appropriate. Align the two ends of the locking mechanism and set the code to lock; follow the included instructions to set or reset your personal numeric combination. Store the combination in a safe place and test the code after setting it to confirm reliable operation. Avoid forcing the mechanism if it does not turn smoothly and keep the sleeve clean to prevent debris from entering the lock.

What to consider before purchase

• Assess typical parking environments — low-risk short stops versus long-term or high-risk areas
• Decide if keyless numeric combination is preferable to a keyed lock
• Consider chain length and flexibility needed to secure the bike to common fixtures
• Color preference and visibility for children’s use

Usage recommendations

For improved security, lock the frame and at least one wheel to a solid fixed point and combine this chain lock with a secondary lock for longer or higher-risk parking. Regularly inspect the chain and combination mechanism for wear or damage and keep the protective sleeve clean to maintain ease of use.
