Despite not emerging victorious in our lock test, the lock I favorably recommend is now priced lower than the top-performing OnGuard RockSolid lock during the Amazon Prime Day Sale.
The Abus Granit Super Extreme 2500 is a heavyweight U-lock designed for maximum theft resistance, boasting a tough tungsten carbide reinforced shackle, a large locking area, moderate weight for its size, and top-tier security certification.
Key Features
- Weight: Approximately 2.1 kg (4.6 lbs), though slight variations or packaging may cause the weight to be listed as 2.51 kg (5.5 lbs) in some sources.
- Shackle material: Made from a special tungsten carbide composite, which is extremely hard (second only to diamonds), combined with hardened steel for the shackle, housing, and load-bearing parts. This material mix provides outstanding resistance to angle grinder attacks.
- Locking area (inner dimensions): Height approximately 22–23 cm (8.6"–9.1"), width about 10 cm (4"). This gives a total usable locking area around 220 cm².
- Security rating: Rated Sold Secure Diamond and has a protection class of 15/15, indicating very high security suitable for high-theft risk areas.
Additional Details
- The 27 mm thick square parabolic shackle balances toughness and reach for securing larger bike frames, such as e-bike downtubes.
- It includes a versatile on-bike mounting bracket (USH 2500), which makes it easy to carry without rattling.
- Despite its size and high security, it is considered relatively lightweight and portable for a lock of this class.

The Abus Granit Super Extreme 2500 is the third most expensive overall in the tested bike locks, but offers exceptional value due to its high level of security and solid functionality. The lock has a high level of security, feels solid to use, and has little to no play in the shackle. Additionally, it comes with an excellent rack mount, which is an additional purchase on the Litelok X3.
In conclusion, the Abus Granit Super Extreme 2500 is a heavyweight U-lock designed for maximum theft resistance with a tough tungsten carbide reinforced shackle, large locking area, moderate weight for its size, and top-tier security certification.
