Description

GZR U4 is a robust U-lock designed to protect your ride from theft. The 16mm thick steel shackle is highly resistant to cutting, and the four-star ART security rating ensures that even skilled thieves won’t easily crack it. Thanks to its sturdy construction, a U-lock is harder to break than other locks and can be conveniently mounted to your bike frame with the included bracket.

The ART foundation is an organization that has developed a five-star rating system to evaluate the theft resistance of bike locks:

• 1 star: Minimum protection
• 2 stars: Basic bikes
• 3 stars: Mopeds
• 4 stars: Motorcycles for temporary parking
• 5 stars: Motorcycles for long-term storage

Regularly oil the lock mechanism with light oil to ensure smooth operation and prevent freezing.
