In 2015, David Millar met with Brompton CEO Will Butler-Adams. David expressed he rarely used a bike in the city, only for training and competing, so the conversation turned to what would be the best Brompton for a die-hard roadie, not a pastiche but a bike that was lightweight, stripped-down, dynamic to ride but useful day to day. That conversation created the collaboration and was the moment the idea for the Brompton x CHPT3 was forged.


2016 saw the first prototype of the Brompton x CHPT3 come to life. David had been using a series of different Brompton’s the previous year, working out through trial and error the spec required for the CHPT3 version. His racing DNA shone through, the brief was simple: lighter, stiffer and more aggressive in ride and feel, in fact, it was even simpler, could we make a Brompton feel like a BMX? It seemed appropriate that it’s testing ground was the 2016 Tour de France where David and Ned Boulting rode them before and after stages for three weeks all over France, even over some of the highest mountains.


2017 saw the CHPT3 Brompton development continue, production was scheduled for the end of the year, titanium parts were being stockpiled at the new factory in London and Scwhalbe worked on producing the tan wall tyres that would match David’s racing bikes. The bike went with David everywhere and was becoming well known in the road cycling scene, the final production prototype was delivered for the 2017 Tour de France, where once again it was ridden throughout the race displaying a versatility that impressed everyone. The CHPT3 Project Manager at Brompton, Andrew Finkill, comes from a mountain biking background and had embraced the challenge of creating a new type of Brompton with CHPT3: the V1 was ready to go.

2018 V1

2018 saw the first CHPT3 Brompton’s come off the factory line, initially limited to 500 it soon became clear the demand exceeded supply. The three years since the initial meeting between Will Butler-Adams and David Millar had seen more than product development, it created a relationship built on mutual respect, both Brompton and CHPT3 became fascinated by each other’s worlds of cycling. The V1 joined these two types of cycling together, practicality x performance, titanium forks and rear triangle, custom tyres and saddle, ergon grips and an overall look and feel that morphed the bike from commuting to racing without losing any of its core purpose.


said Will Butler-Adams OBE, Brompton CEO. “Two heats, 24 people in each heat, 12 of whom went forward and we just saw the mental ride, with people haring round the track, down to the last 2 ending in an epic ride at the end. Alec blasted in and won £10,048, the biggest prize money in the UK, what a day.”


David and Ned were no longer the only people at the Tour de France with CHPT3 Brompton’s. Others realised it was the best way to find some play in your work while on the road for three weeks. Equally at home on the roads of the Tour de France or the daily commute to work, the CHPT3 introduced a whole new type of cyclist to the Brompton way of life.

2019 V2

2019 saw the launch of the V2 bike, an evolution rather than a revolution, the concept remained the same with the details refined and improved. The Brooks saddle and Ergon grips were replaced by industry leading British company, fabric. The Schwalbe ONE tyres were developed especially for the CHPT3 V2 - the tan-wall with 35mm width lowers rolling resistance and uses extremely cut-resistant high tech fibre so maintaining a high level of puncture resistance. The rear suspension block is race-tuned, offering a stiffer more responsive ride allowing for improved handling. The fire red front tube is complimented by a textured black main frame as well as titanium forks and rear triangle. More and more events were taking place around the world: from the CHPT3 Supercar Scramble to the Jakarta CHPT3 Club, and of course, the Brompton World Championships where the men’s and women’s races were both won on CHPT3 bikes.

2020 V3

Five years since the collaboration began yet it feels like things are just starting. 2020 sees the launch of the V3 and the creation of a club for owners and fans. What we didn’t expect when we designed and built the CHPT3 Brompton was to also build a community of people - a pure product design project has turned into a design for life. For that reason in 2020 saw the launch of an official home and hub for owners and fans of the bike and style.


The street riding the CHPT3 Brompton encouraged us to dive into has now become a pillar of what we do. We wanted to tell the stories of others who use their Brompton's to find freedom and express themselves wherever they called home.
