Top Lock U-lock ART4 24.5 cm

This lock has a 4-star ART approval. This means that the lock is accepted by almost all insurance companies for taking out theft insurance for a motorcycle or scooter. A chain lock with the same rating would be too heavy to be practical for a bicycle, and that's the great advantage of a U-lock compared to a chain lock. U-lock's tend to be lighter, more compact and therefore easier to handle than a chain lock of the same strength.

ART Rating

The best way to check the real security level of a lock is to look for an official rating. The best known is the Dutch organization, ART. For bicycle locks the industry standard for insurance companies is an Art 2 Star rated lock, meaning that insurance companies will only insure a lock rated ART 2 and above for a bicycle.
