Our most secure bike locks are therefore equipped with the ART certification, indicating how well the lock is secured against theft. There are distinctions between five categories. The higher the number of stars, the better this lock secures your bike. A bike lock with the ART-3 certification provides even more security.

Securing your bike against theft is crucial, and it's wise to invest in a good bike lock. Locks with the Sold Secure certification undergo thorough testing and are then classified based on the level of security. Sold Secure distinguishes three levels: bronze, silver, and gold. A bike lock with a gold classification is suitable for parking your bike for more than an hour in areas with a higher risk of theft, such as large towns or cities, or for individuals living on a university campus, for example.
