Features and Construction

The lock is built around an alloy body that houses both the locking mechanism and the alarm. This dual function means you get physical security plus an audible deterrent when the lock is tampered with.

Material and Build

The alloy construction gives the lock a solid feel and resistance to everyday wear. It is designed to withstand outdoor conditions thanks to its waterproof build. The alarm system is integrated into the lock body, powered by six AG13 button batteries. Three keys are provided, so you have spares for convenience or to share with another user.

Size and Practical Fit

Weighing 440g, the lock is substantial enough to feel secure yet manageable to carry. It fits standard disc brake rotors on bicycles, motorcycles, and electric cars. The compact design allows it to be stored in a bag or under a seat when not in use. The optional reminder rope helps you remember to remove the lock before riding off.

Uses and Placement

This lock is suitable for both everyday commuting and longer parking periods. It can be used on a variety of two-wheeled vehicles, offering flexibility across different ownership situations.

Event or Professional Use

For those who use their bikes or motorcycles professionally, such as delivery riders or event staff, this lock provides a visible security measure. The alarm adds an extra layer of protection in busy areas where vehicles may be left unattended for periods. The waterproof rating ensures it remains functional even if it rains during a shift.

Everyday Home Use

For daily commuters or occasional riders, the lock offers peace of mind when parking outside shops, at work, or at home. The three keys mean you can keep one on your main keyring and leave a spare at home. The choice of black or silver lets you coordinate with your vehicle's look. The reminder rope is a simple but effective way to avoid riding off with the lock still attached.

Benefits and Buying Value

Reuse and Low Maintenance

The lock is designed for repeated use. The alloy body can be wiped clean with a dry cloth if it gets dirty or wet. The AG13 batteries are widely available and easy to replace when needed. The three keys reduce the risk of being locked out if one is lost. The waterproof build means you do not need to worry about rain damage during normal use.
