Turning a new page in the Brompton and CHPT3 story, the latest collaboration brings a fresh dynamic to a proven partnership. One founded on fun, practicality, and high performance. 

Drawing on Brompton's previous three collaborations with David Millar of CHPT3, they turn to page 4, and the horizon broadens. A bike that originated as a city commuter and became a daily workhorse for David, a former pro-cyclist, is now embraced by a community who see beyond simply departing from point A and arriving at point B.

The Brompton x CHPT3 could be called an unlimited edition bike. It draws on the need for core Brompton practicality yet fulfills the desire for performance, causing you to stray from the shortest distance between two points. It’s everything you need and nothing that impedes your progress. Not a folding bike you could ride anywhere, but rather a bike that you will ride everywhere that also folds.
