ONGUARD K9 Heavy Duty Link Plate Lock

The ONGUARD K9 Heavy Duty Link Plate Lock is a high-security folding lock engineered to provide superior protection for bicycles against theft. Constructed with hardened steel link plates, this device offers exceptional resistance to cutting, sawing, and prying attempts. Its innovative folding design allows the lock to be collapsed into a compact shape, making it convenient to carry while riding. This lock is an essential accessory for urban cyclists who need a reliable and portable security solution for parking their bikes in high-risk public environments.

Advantages

The primary benefit of the ONGUARD K9 is its robust construction, which combines the strength of a traditional U-lock with the flexibility of a chain. The hardened steel plates are designed to withstand significant physical force, providing peace of mind when leaving your bicycle unattended. Furthermore, the compact folding mechanism ensures that the lock does not interfere with your pedaling or bike handling, as it can be easily mounted to the frame using the included bracket. The weather-resistant coating protects the lock mechanism and the bicycle frame from scratches and environmental damage.

Suitable for

• Securing bicycles in urban environments
• Commuters who require a portable and compact security device
• Cyclists parking in public areas with moderate to high theft risk

When it may not be suitable

This lock may not be suitable for securing bicycles in extremely high-risk areas where heavy-duty power tools are likely to be used, as no portable lock is entirely immune to such equipment. Additionally, it may not be the best choice for users who prefer the lightweight nature of cable locks, as the heavy-duty steel construction adds noticeable weight to the bicycle.

Key specifications

• Hardened steel link plate construction
• Folding design for compact storage
• Weather-resistant protective coating
• Includes frame-mount bracket
• High-security locking mechanism

How to use

To use the ONGUARD K9, unfold the link plates and wrap them around the bicycle frame and a secure, immovable object such as a bike rack or post. Once positioned, insert the locking end into the cylinder and engage the key to secure the mechanism. Ensure that the lock is positioned away from the ground to prevent leverage attacks. When not in use, fold the plates back into their compact configuration and secure the lock into the provided frame-mount bracket for easy transport.

What to consider before purchase

• Compatibility with your bicycle frame for mounting the bracket
• The weight of the lock relative to your riding style
• The length of the lock required to secure your bike to various types of street furniture

Usage recommendations

Regularly lubricate the locking cylinder with a silicone-based spray to ensure smooth operation and prevent debris buildup. Always lock your bicycle to a solid, permanent structure and ensure the lock captures both the frame and, if possible, the rear wheel.
