Brompton C-Line Racing Green

The Brompton C-Line Racing Green is a 6-speed folding bike handcrafted at Brompton's factory in London. The high-tensile steel frame — made from drawn, heat-treated tubes brazed with selected self-brazing joints — delivers a level of stiffness and durability that's rare in a bike this compact. The Racing Green finish gives it a clean, confident look well-suited to city riding.

The 6-speed transmission pairs a Sturmey-Archer 3-speed internal hub with two external sprockets (13T and 16T), controlled by two independent trigger shifters. This combination covers a 300% gear range, handling everything from flat urban stretches to bridges and gentle inclines. The forged 6061 aluminium crankset with a 50T chainring and integrated chainguard keeps the drivetrain tidy and low-maintenance.

The 16-inch wheels (ETRTO 349) run double-walled 28-spoke rims fitted with Schwalbe Marathon Racer tyres — puncture-resistant with reflective sidewalls for added safety in poor light. Brompton Dual Pivot Caliper brakes provide reliable, modulated stopping power suited to small-diameter wheels. The M-type handlebar positions the rider semi-upright with a hand height of approximately 1013 mm, comfortable for a wide range of riders.

Folded, the bike measures just 645 × 565 × 270 mm — compact enough to slide under a seat on the train or tuck into a corner of the office. The front luggage block gives access to the entire Brompton bag ecosystem, so you can carry what you need without adding a rear rack. A practical, well-built companion for anyone who moves through the city every day.
