One-Click Frame Lock for Quick, Everyday Stops
The Abus 4750S Pro Amparo is a frame-mounted lock that makes quick errands and coffee stops simpler and more secure. Once installed on the rear triangle, a single turn of the key drops an 8.5 mm hardened steel bar through the rear wheel so the bike cannot be rolled away. It is basic immobilization that is always with the bike, no extra lock to remember.
Designed with a large wheel opening, the 4750S clears most city and e-bike tire and fender combinations. The lock body includes a port for Abus plug-in chains or cables (sold separately), so you can add a second lock to secure the bike to a rack when you need more than just a quick “no roll” lock-up.
