Frequently Asked Questions
Is the mounting bracket included with the lock?
No — the USH2500 bracket is sold separately. Abus designed the lock to be compatible with the USH2500 bracket for secure frame mounting, but if you prefer not to use the bracket you can carry the lock in a pannier or backpack. Always ensure the bracket model matches the 2500 series for a secure fit.
How resistant is this lock to angle grinders and powered tools?
The Granit Super Extreme 2500 is reinforced with Wolfram (tungsten) carbide at critical points and carries the Sold Secure Powered Cycle Diamond rating, meaning it has been tested against battery-powered angle grinders and similar tools. While no lock is truly unbreakable, this model is one of the strongest commercially available and will dramatically slow or deter professional thieves.
What does the X-Plus cylinder and 'one key' option mean?
The X-Plus cylinder is Abus's high-security locking core offering excellent pick and drill resistance. The 'one key' option lets you order multiple Abus products keyed alike so a single key can open other locks from the same key-code family, simplifying daily use.
Will the lock fit my bike and rack?
With internal dimensions of 165 x 230 mm (6.5" x 9"), the lock fits most frames and allows locking a frame and rear wheel to a standard post or rack. Measure the distance between your frame and the anchor point to confirm fit — large frames or thick rails may require a larger clearance.
Is this lock too heavy for commuting?
At about 5 lb, the Granit Super Extreme 2500 is heavier than many commuter locks. It's intended for riders prioritizing maximum security (especially e-bike owners). If weight is a concern, consider carrying it in a pannier or using a lighter secondary lock for short stops.
Does Abus offer a warranty or key replacement service?
Abus typically supports key replacement when you register the product or keep the key code supplied with the lock. Warranty coverage varies by region and seller; check Abus's official warranty terms or contact Forest Bikes customer service for assistance with registration, replacement keys, or warranty claims.
Buying Guide
When choosing a U-lock for high-value bikes—especially e-bikes—prioritize shackle thickness, material reinforcement and cylinder security. Look for locks with hardened steel shackles, added carbide or ceramic reinforcement, and certified ratings like Sold Secure Powered Cycle Diamond for resistance to powered tools. Match internal clearance to your typical locking scenarios (frame + wheel vs. frame + post), consider how you'll carry the lock (bracket vs. pack), and accept the weight-security tradeoff. For maximum protection, pair a strong U-lock with a secondary cable or chain for loose components and consider insurance for expensive e-bikes.
