Brompton C Line 12-speed “M12L” 1975 50th Anniversary Edition

Brompton C Line 1975 Edition

London, 1975. Andrew Ritchie, a brilliant young inventor, put pen to paper and sketched our original folding bike, calling it the ‘bike of the future.’ It was a radical departure from bicycles of the day – the first in a line of iconic designs which, today, represent the gold standard in folding bicycles.

The 1975 Edition is a tribute to 50 years of innovation, excellence, and the people who make it possible.

Each detail tells a chapter of our story. The Thermal Fade finish evokes the brazing process used by our team to produce bikes that last a lifetime. Each bike comes with one of 1,975 collectible ‘Brazer’s Coins’ as a tribute to our team’s talent and dedication. And, of course, there’s 50th anniversary gold wherever you look because this is a moment to celebrate!
