Brompton C Line folding bikes

The Brompton C Line is the "Core" range of Brompton bikes - available (since 2023) with two (since 2025) three gearing choices:

• 2-speed (previously known as Urban)
• 6-speed (previously known as Explore)
• 12-speed (introduced in 2025)

All C Line Brompton folding bikes come with the following standard equipment - in previous years some of this was optional 

• Mudguards front and rear
• Front carrier block for carrying luggage on the front of the Brompton

The C Line is available in 3 handlebar types / handlebar ride heights

• Low - this was previously known as the S-type with a low / sporty ride position comparable with a drop handlebar racing / road bike
• Mid - this is the classic Brompton handlebar type previously known as the M-type
• High - this has the same shape bars as the Mid but with a slightly longer stem to give a more upright riding position as popular in The Netherlands / Germany and the Nordic countries. This handlebar type is also good for very tall riders who do't want to lean forwards too much when riding

The C Line comes as standard with a choice of 3 seat post heights

• Standard - for riders with up to a 31 inch inside leg
• Extended - for slightly taller riders with an inside leg up to 35 inches
• Telescopic - for very tall riders
• We also offer a shorter (6cm shorter than the standard) seat post for very short riders

The C Line comes in a range of colours - for 2025 these are:

• Black
• Bumblebee Yellow
• Dune Sand
• Gloss Black Lacquer
• Ocean Blue
• Racing Green

Additionally the 12-speed C Line also is also available in:

• Flamingo Pink
• Turkish Green
• Amethyst Lacquer

With regards to colour the Brompton C Line bike can have (with the exception of the Gloss Black Lacquer) different colour frame and extremities (so for example a red main frame and green forks, rear triangle and handlebar stem)

We think that the most important thing in selecting the right size is a test ride on a Brompton demo bike (or 3) so you get try all handlebar types and see which feels best for your riding style
