The Brompton fold

Invented by our founder, Andrew Richie, in 1975, 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

Bromptons are made different. We engineer an efficient solution for moving around the city and beyond. Ours is a bike that does more than the obvious, it answers problems owners say they didn't know they had. ‘You don’t get Brompton until you get a Brompton.’
