Whether navigating bustling streets, hopping on a train, or tucking itunder a café table, the C Line is designed to move with you effortlessly. Nowfeaturing a new 12-speed system, it delivers an impressive gear range—matching,if not exceeding, traditional road and commuter bikes—all while maintainingBrompton’s renowned compact design. The Advance Rear Frame takes portabilityeven further, allowing riders to glide and steer their folded bike with ease,thanks to larger, smoother-rolling wheels.
