Protect your pride and joy with the Amperio Citadel, a Sold Secure Gold-rated U-Lock engineered for high-risk areas.

Your e-bike is a significant investment, and it deserves the highest level of protection. The Amperio Citadel U-Lock provides exactly that. Independently tested and awarded the coveted 'Gold' rating by Sold Secure, this lock is built to withstand the most determined attacks from thieves. It’s the ultimate peace of mind for any rider who has to leave their bike unattended in a city centre, at a train station, or on a university campus. Don't let the fear of theft stop you from riding; lock it down with the Citadel.

At its core is a 14mm MAX-Performance hardened steel shackle, designed to resist bolt cutters, leverage attacks, and sawing. This is paired with a double deadbolt locking mechanism that provides exceptional holding power by securing both ends of the shackle within the crossbar. The high-security, disc-style cylinder is pick and drill-resistant, while a weatherproof vinyl coating protects your bike's paintwork from scratches. We even include a convenient frame-mounted bracket for easy transport, and three keys, one of which has a built-in LED light to help you find the keyhole on dark evenings.
