The Brompton folding system.
Invented in 1975 by Brompton founder Andrew Richie. Expertly engineered to transform the bike into a small, locked package a little larger than its wheels - all in under 20-seconds. Nothing folds like a Brompton folds.
Not like other bikes.

Each bike is hand-built and quality-assured at Brompton's London factory to cope with the daily demands of city riding. All Brompton bikes are powder coated in the London factory's in-house paint facility using environmentally friendly powders and energy from renewable resources powder coated.
