The original folding bike
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.
New 4-speed system
The latest development is the C Line 4-speed, brought in to accompany the 2 and 6-speed options. First seen on the P Line model, Brompton's unique 4-speed system is an expertly engineered solution that gives riders more gears and more range. It takes portability of Brompton’s classic bike to a whole new level, thanks to an Advance Rear Frame which allows owners to glide and steer their folded bikes through railway stations and entrance foyers with the seat post locked halfway up.
New Colors
The Brompton C Line 4-speed is available in three new exclusive colors: Cloud Metallic, Plum Red & Palm Green.
