Recommended use

This alarm lock is designed to secure a parked two-wheeler outside a home, in a car park, in the city centre, outside a shop, on a campus or near a workplace. It can be used for both short stops and longer parking periods. Thanks to its compact size, it is suitable for users who need a lightweight, space-saving anti-theft system for their daily journeys.

It is particularly suitable for:

• Bicycles fitted with disc brakes
• Electric bikes and electric mountain bikes
• Electric or petrol scooters
• Small motorbikes and motorcycles
• Users looking for a brake disc lock with an audible alarm

Product features

The system works directly on the brake disc by blocking the rotation of the wheel. This protection method is widely used for powered two-wheelers and modern bicycles fitted with disc brakes. The alloy structure provides good mechanical strength while keeping the weight moderate, making it easy to carry every day.

The anti-corrosion finish helps limit the effects of moisture and water splashes. This lock is therefore suited to more reliable outdoor use, particularly for people who often park their vehicle on the street or in uncovered areas. Its green colour can also act as a visual reminder to avoid forgetting the lock before setting off again.

The compact format is an important advantage for urban use. It is easy to handle and quick to fit onto the brake disc without requiring tools. This type of anti-theft lock is well suited as a complement to another security device, such as a chain or D-lock, to increase the vehicle’s overall level of protection.
