The Brompton C Line 4 Speed is the definition of clever British engineering — a hand-built folding bike that rides as well as it folds. Designed for urban riders who want speed, simplicity, and flexibility, it transforms from a full-sized bike into a compact, easy-to-carry package in just 20 seconds.

Built in Brompton’s London factory, the precision-drawn, heat-treated steel frame is hand-brazed by skilled craftsmen for exceptional strength and durability. Every detail is finished with a durable powder coating, and the folding mechanism is engineered for smooth, reliable use day after day. The result is a bike that’s as robust as it is elegant — ready to handle the demands of daily commuting, travel, or city exploration.

The 4-speed gearing system combines a 2-speed internal rear hub with a 2-speed external derailleur, giving a wide range for hills and flat city streets alike. The Brompton trigger shifters make gear changes light and intuitive, while the dual-pivot caliper brakes deliver reliable stopping power and control in all conditions.

Rolling on 16" Schwalbe Marathon Racer tyres, this bike feels quick, nimble, and stable, with puncture protection and reflective sidewalls for extra peace of mind. The forged aluminium chainset with chainguard keeps your ride smooth and your trousers clean.

Compact when folded, the C Line fits neatly under a desk, on public transport, or in a car boot. It’s light enough to carry and designed to roll easily on small wheels when folded — ideal for mixed commutes or travel adventures.

Handmade with over 90% renewable energy, every Brompton is built to last and built to be ridden. The C Line 4 Speed gives you the freedom to move through the city with ease — agile, reliable, and always ready for wherever your day takes you.
