C Line is the original steel folding bike built for the city. Proudly handmade in London since 1975. It transforms from a go-anywhere vehicle to a small, locked package in under 20 seconds. Easy to lift, carry or store. You can take it on trains, tuck it in car boots or under restaurant tables. Add luggage, run a rack, and even store a toolkit inside the frame.
The Brompton C Line 12-speed is available in three new exclusive colours, Palm Green, Plum Red and Cloud Metallic.
Brompton bikes expertly undergo a meticulous powder-coating process using environmentally friendly powders, all powered by 100% renewable energy. With seven striking colours to choose from and new shades released throughout the year, your ride is as unique as you are.
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.
