## Long description

ONGUARD Bulldog Medium DT bicycle lock in yellow (model 8015M) is a compact articulated chain lock designed for everyday urban use. The flexible chain construction allows the lock to wrap around bicycle frames, wheels and secure fixed objects such as poles or bike racks. The protective sleeve reduces paint damage and increases handling comfort while carrying. This lock is positioned for commuter and short-term parking needs where a portable, easy-to-use chain solution is required.
Advantages
The articulated chain design provides flexibility to secure awkward frame geometries and larger fixed objects while maintaining consistent closing points along the chain. A protective outer sleeve prevents metal-to-paint contact and reduces noise and wear. The medium length balances portability and reach, making it easier to carry on rides or store in panniers and backpacks. The visible yellow finish improves daytime visibility and helps identify the lock among other gear.
Suitable for
 Commuter bicycles during short stops and errands
 Securing scooters or children’s ride-on vehicles for brief parking
 Urban environments with bike racks, poles or fences
 Riders who need a portable chain solution with moderate security
Key specifications
 Lock type: articulated chain with integrated lock housing
 Finish: yellow protective sleeve over chain
 Length category: medium — designed for short to moderate reach
 Intended use: everyday urban and commuter applications
 Portability: compact for carrying in bags or mounting with accessories
How to use
Wrap the articulated chain around the bicycle frame and a fixed object such as a rack or pole so that both frame and wheel are secured where possible. Insert the chain end into the lock housing and engage the locking mechanism according to the supplied key or code system. Ensure the protective sleeve covers metal contact points to avoid scratching the frame. Store the key in a secure place and check the lock before leaving the bicycle to confirm it is fully engaged.
Usage recommendations
For higher-risk locations or extended parking periods, use this medium articulated chain in combination with a secondary lock or choose a higher-security chain model. Position the lock to minimize leverage on the locking mechanism and avoid leaving the bicycle in isolated, poorly lit areas when possible.
