## Long description

The Onguard Doberman 8031 is a cable/chain-style bike lock from ONGUARD designed to provide flexible, everyday security for bicycles and similar personal transport. Combining a braided cable with chain links and a keyed cylinder, this lock allows you to secure frames, wheels and accessories when parking in urban environments or at transit stops. Its design balances flexibility for easy wrapping around fixed objects with resistance against casual tampering, making it suitable for short- to medium-term parking and as part of a layered security approach.
Advantages
The cable/chain construction offers adaptability to different locking points while maintaining moderate cut resistance compared with simple cables. A keyed cylinder provides consistent locking and unlocking, and the overall weight and flexibility make the Doberman 8031 easy to carry or stow on most bikes. The lock’s configuration permits securing multiple parts of the bicycle simultaneously, reducing the risk of component theft when combined with a rigid lock or anchor.
Suitable for
Everyday urban bike parking
Short- to medium-term stops at shops, transit stations, or workplaces
Securing frames, wheels and accessories in combination with fixed anchor points
Use as a secondary lock in a layered security setup
Key specifications
Type: cable/chain hybrid lock suitable for bicycles
Locking mechanism: keyed cylinder
Construction: braided cable integrated with chain links for flexibility
Use case: designed for everyday urban use and short- to medium-term parking
Portability: flexible and compact for easy carrying or storage
How to use
Wrap the cable/chain around an immovable object and through the bicycle frame and at least one wheel, then engage the keyed cylinder and remove the key. Ensure the lock is routed to minimize leverage points and keep the cylinder facing downwards where possible to reduce exposure to dirt and moisture. For best results, use the Doberman 8031 in combination with a rigid D-lock or fixed anchor when leaving the bicycle for longer periods or in higher-risk areas.
Usage recommendations
Store keys in a secure place and carry a spare key separately. Inspect the cable and locking mechanism periodically for damage or wear. Avoid exposing the lock to prolonged heavy rain or salt without drying and light lubrication of the cylinder to maintain reliable operation.
