ART approved

The ART certification is one of the most important standards for chain locks and other locks for two-wheelers such as bicycles, scooters, and motorcycles. The ART Foundation tests and certifies locks for theft resistance: the more stars a lock receives, the higher its security. Below is an overview of the different ART levels and what they mean.

ART 1

• Meaning: Basic protection; guards against simple and quick force.
• Use: Short-term parking in well-monitored or private areas.
• Insurance: Often not recognized by insurers.
• Security: Easily forced with basic tools; minimal protection.

ART 2

• Meaning: Standard protection against limited professional tools.
• Use: Short-term parking in areas with some supervision or locked garages.
• Insurance: Sometimes recognized for basic theft coverage.
• Why: Offers slightly more resistance but still vulnerable to targeted attacks.

ART 3

• Meaning: Enhanced protection against more advanced tools and longer attempts.
• Use: Unmonitored public areas for short to medium parking periods.
• Insurance: Usually recognized by insurers as minimum requirement for motorcycle theft coverage.
