Brompton 1975 Edition C Line 12 Speed Mid Handlebar Folding Bike

Season:2026

The Brompton 1975 bike. The Gold Standard. A tribute to 50 years of innovation, excellence, and the people who make it possible.

The Thermal Fade finish is inspired by the colours created during the crucially important frame brazing process.

Brazing is the method we use to create a strong and stable bond between the steel tubes that come together to make a Brompton frame. The frame is the heart of every bike, and brazing produces a high-quality, and super-durable result.

A highly skilled craft, our brazers are trained in-house for 18-months. Some Master Brazers have been crafting our bikes for over 20 years – passing on their well-honed skills to the newer team members. Each brazer has their own unique style and a small signature at the bottom of every bike frame marks that maker.

    • Thermal Fade lacquer frame - The Thermal Fade finish evokes the brazing process used by our team to produce bikes that last a lifetime.
    • 1975 Edition Serial Plate - Own 1 of 1,975 limited edition Bromptons with a individually numbered gold serial plate.
    • Gold Anniversary Details - Everything from the logo to the bell is done up in gold to celebrate 50 years of innovation and excellence.
    • Brazer’s coin - Each brass coin is embossed with one of our brazer’s initials. The material will naturally patina over time, making it as unique as your Brompton bike.
    • Brompton 1975 Edition saddle - With a premium carbon base that’s light and agile. Strong Chromoly rails. A specially designed integrated carry handle. 23% lighter than the standard UK Brompton saddle.
