C Line - 12-speed - Renewed - Grade A

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.

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.
