About the Brompton C Line 12-speed – Low Handlebar
The original Brompton folding bike. With a robust steel frame, proudly handmade in London. The most customisable Brompton model, there’s a C Line for everyone.
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.
T The latest development is the C Line 12-speed, brought in to accompany the 2 and 6-speed options. First seen on the P Line model, Brompton's unique 12-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.
Extended Warranty
Brompton offers an extended 7-year frame warranty, and a 2-year warranty on all other non-wearing parts. Simply visit the Brompton website to register with your frame number.
