For those who love their e-bike, cargo bike, or bicycle in general, protecting it to the fullest extent is a priority – even against theft attempts using angle grinders. In developing the Granit Super Extreme 2500, great attention was paid to achieving the highest possible resistance against attacks with angle grinders, as this method of overcoming bicycle locks is becoming increasingly common in urban areas. Our special carbide material mixture around the lock shackle and body is the answer to this phenomenon, making it particularly difficult for thieves. The shackle, housing, and construction parts of the lock are made from hardened steel. The Abus XPlus cylinder offers high protection against manipulations such as picking. If you want to secure your bike properly, lock it with the Granit Super Extreme 2500. The USH 2500 holder for the lock can be flexibly attached to the bike thanks to plastic-coated metal mounting brackets and optional screw holes. Helpful for installation: When attaching, you can pivot the holder by loosening two screws. To prevent the lock from rattling in the holder during rides, it is secured with both ends of the shackle in the USH 2500. It is unobtrusive while riding and secure when parked.
