Spiral cable bike lock DUNLOP 12 mm x 1500 mm — spiral cable security for bicycles

The DUNLOP spiral cable bike lock with a 12 mm diameter and 1500 mm length is a flexible security solution for bicycles and micromobility vehicles. Its coiled design reduces storage space while allowing extended reach to secure a frame and wheel to a rack, post or other fixed object. The cable construction balances portability with basic theft deterrence for everyday urban use.

Advantages

The spiral cable is compact when coiled and quickly extends to provide sufficient length for most locking situations. A 12 mm thickness offers greater resistance to casual cutting tools than thinner cables while retaining light weight for carrying on a bike or in a bag. The flexible construction adapts to different attachment points and reduces the risk of damage to paint or components compared with rigid locks.

Suitable for

• Securing bicycles in urban or campus environments for short to medium periods
• Locking micromobility vehicles such as e-scooters and foldable bikes
• Supplementing a primary lock to secure wheels or accessories

Key specifications

• Cable diameter: 12 mm
• Overall length (coiled state extended): 1500 mm
• Coiled spiral design for compact storage
• Flexible cable construction suitable for varied attachment points
• Lightweight for transport on a bike or in a bag

How to use

Wrap the extended spiral cable around the bike frame and a secure fixed object, threading the cable through the frame and wheel if possible to reduce theft risk. Engage the lock mechanism according to the integrated locking method (key or combination) and verify the connection is snug and the cable cannot be easily slipped off. After use, retract the cable into its coiled form and stow it in a bag, saddlebag or attached mount to keep it protected and readily available.

Usage recommendations

For improved protection, use this spiral cable as a secondary lock in combination with a robust U-lock or chain lock when leaving a bicycle unattended in higher-risk areas. Regularly inspect the cable and locking mechanism for wear or damage and replace if any compromising signs appear.
