The latest development is the C Line 12-speed, brought in to accompany the 2 and 6-speed options. First seen on the P Line model, Brompton's unique 12-speed system is an expertly engineered solution that gives riders more gears and more range. It takes portability of Brompton’s classic bike to a whole new level, thanks to an Advance Rear Frame which allows owners to glide and steer their folded bikes through railway stations and entrance foyers with the seat post locked halfway up.

The Brompton C Line 12-speed is the ultimate city companion, blending iconic British craftsmanship with cutting-edge portability. Proudly handmade in London since 1975, our bikes transform from a full-sized ride into a compact, locked package in under 20 seconds. Whether navigating bustling streets, hopping on a train, or tucking it under a café table, the C Line is designed to move with you effortlessly. Now featuring a new 12-speed system, it delivers an impressive gear range—matching, if not exceeding, traditional road and commuter bikes—all while maintaining Brompton’s renowned compact design. The Advance Rear Frame takes portability even further, allowing riders to glide and steer their folded bike with ease, thanks to larger, smoother-rolling wheels.

Personalisation has always been at the heart of Brompton, and the C Line 12-speed continues this tradition with three striking new colours: Cloud Metallic, Palm Green and Plum Red. Its unique Brompton Luggage System ensures a stable ride, even when carrying heavy loads, by keeping weight on the frame rather than the handlebars. Whether you're commuting, adventuring, or simply enjoying the ride, the C Line 12-speed is a versatile, stylish, and practical bike that redefines urban mobility.
