## Long description

ONGUARD Mastiff is a universal bike accessory mount designed to attach locks and similar security devices to bicycle frames or handlebars. The compact bracket keeps a U-lock, folding lock or other compact security device securely fastened and readily accessible while riding or storing the bike. Compatible with a range of tube diameters, the Mastiff mount offers a practical solution for commuters and urban cyclists who need to carry a lock without using panniers or backpacks.
Advantages
The Mastiff bracket provides tool-free installation and a low-profile fit that minimizes movement and noise during rides. Its adjustable mounting system adapts to different tube shapes and diameters, enabling placement on frames or handlebars. Constructed to hold common compact locks securely, the mount allows quick attachment and removal of the lock for convenient daily use. The design balances stability and accessibility so the security device is easy to reach when needed yet remains out of the way during cycling.
Suitable for
Commuting and urban cycling where quick access to a lock is required
Bikes with round or slightly oval frame tubes and standard handlebars
Transporting U-locks, folding locks and compact chain locks
Short-term bike storage and quick stops in city environments
Key specifications
Universal bracket compatible with a range of tube diameters (adjustable clamp)
Mounting position: frame tubes or handlebars
Designed for compact U-locks, folding locks and similar security devices
Low-profile form factor to reduce interference while riding
Tool-free installation and quick-release style attachment
How to use
Position the Mastiff bracket on a suitable section of the frame tube or handlebar where it will not obstruct controls or rider movement. Adjust the clamp to fit the tube diameter and secure the bracket using the integrated fastener until it is stable and does not rotate. Slide or clip the compatible lock into the bracket according to the lock manufacturer’s orientation so the lock is held firmly. Before each ride check that the bracket and lock are secure and that the lock does not contact moving parts such as the wheel or brake mechanisms.
Usage recommendations
For best results, install the mount on a clean, dry surface and avoid placing it where the lock could rub against cables or clothing. Periodically inspect the bracket and fastening hardware for wear and retighten as needed. If your frame has very large or unusually shaped tubes, verify fit before use or consider mounting on a standard-diameter section such as the seat tube or top tube.
