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.
