Identified by model ONG-8031GLO (EAN 7290001281314), it features a chain-based design with an integrated cable and a keyed cylinder for locking.

## Long description

The ONGUARD Doberman 8031GLO is a chain lock with integrated cable and keyed cylinder designed to secure bicycles and small personal mobility devices. Its chain-based construction allows flexible positioning around frames and fixed objects, while the attached cable extends reach to include wheels or accessories. The lock is intended for everyday urban use to deter opportunistic theft and provide a practical locking solution for commuters and casual riders.
Advantages
The chain design combines strength and flexibility, enabling the lock to wrap around a variety of anchor points. The integrated cable increases versatility, allowing additional components such as wheels or helmets to be secured without needing a separate cord. A keyed cylinder provides straightforward operation and reliable engagement. The overall construction balances portability with theft resistance suitable for routine urban situations.
Suitable for
Securing bicycle frames to bike racks, posts, and railings
Locking wheels or accessories using the integrated cable
Everyday urban commuting and short-term parking
Personal mobility devices and children’s ride-on toys when supported by a chain lock
Key specifications
Chain-based lock with attached cable for extended reach
Keyed cylinder mechanism for locking and unlocking
Designed for urban use and short-term security
Portable weight and flexible length suitable for common anchor points
How to use
Thread the chain around the bicycle frame and a secure fixed object such as a bike rack or post. Use the integrated cable to loop through wheels or accessories that need extra protection, then insert the chain end into the keyed cylinder and turn the key to lock. Keep the key in a safe place; when unlocking, insert the key, rotate to release the cylinder, and withdraw the chain. Inspect the lock periodically for wear or damage and ensure the cylinder remains free of dirt and moisture to maintain smooth operation.
Usage recommendations
For improved security, choose a well-lit, visible location and secure both the frame and at least one wheel. Combine the chain lock with additional locking methods if leaving a bike unattended for extended periods or in high-risk areas. Store spare keys separately from the locked bicycle and clean the cylinder periodically to prevent buildup that could impede the key.
