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.

This bike uses the Low Handlebar which is Brompton’s lowest and sportiest handlebar. This gives a zippy, fast position for riders of average height and a mid-height position for shorter riders - perfect for fast commutes.

The bikes finish takes inspiration from Urban materials. High-shine Gloss Winter Sky and textured Concrete Grey are complimented with Fire Red and Aqua Teal accents. There CHPT3 captures the feeling of inner-city riding.

Aside from the excludive colour the bike is fitted with Schwalbe One Tanwall tires, Premium aluminium touch points, a Fizik Terra Argo Saddle, Ergon GE1 grips, exlusive CHPT3 frame bag and Tublioto inner tubes.
