British cycling icon Brompton has reunited with internationally acclaimed artist Shantell Martin for a new limited-edition Brompton x Shantell Martin P Line, launching Dec. 5 and debuting during Miami Art Week. For urban riders, commuters, and folding-bike fans, this collaboration delivers one of the most striking—and most collectible—city bikes of the year.
A Folding Bike Designed as a Moving Artwork
Martin is known for her signature freehand line drawings, which often explore movement, identity, and storytelling. Her first collaboration with Brompton focused on black-and-white simplicity, but this new P Line limited edition embraces bold colour. Free-flowing lines sweep across the lightweight frame, saddle, and fenders, energized with unexpected pops of pink and burgundy.
The Brompton x Shantell Martin P Line is a peddling piece of artwork
“This project has been a long time in the works, and it’s exciting to finally see it out in the world,” says Martin. “As someone who grew up loving Brompton bikes, it feels very special to collaborate with a brand I grew up admiring. To be able to add something new and unique to Brompton’s legacy – through drawing, through color, through this sense of play – is a real joy. My hope is that people feel that when they ride it: that they’re part of the story, adding their own lines to the journey.”
The result is a folding bike that looks and feels like a piece of contemporary art—a head-turning ride designed for cyclists who want style and performance in equal measure.

Performance for Modern City Cycling
While the artwork makes this bike stand out, the P Line platform is built for the realities of fast-paced urban cycling. The bike features:
-
A lightweight frame ideal for carrying upstairs, onto transit, or into tight storage spaces
-
Responsive handling for navigating traffic, bike lanes, and busy downtown streets
-
Brompton’s renowned fast fold, making it perfect for multimodal commuting
For riders who combine cycling with transit—or anyone who needs a compact, high-performance commuter—the P Lineremains one of the most versatile folding bikes on the market.
Details You Discover Over Time
Part of the collaboration’s magic is its sense of play and discovery. Martin integrated subtle words, shapes, and colour shifts into the design, encouraging riders to notice new details long after their first ride. As Brompton celebrates 50 years of craftsmanship, this idea of continuous exploration felt central to the partnership: a bike that reveals itself slowly, just like a favourite city route you get to know over time.

“When we bring design and art into things we touch and use every day, we’re also bringing more possibility into daily life,” adds Martin. “It can change how you feel about something as simple as a commute or a quick ride to the shop. If more people are exposed to art in these small, accessible ways, I think it can only make the world a little better, a little more open.”
A Must-Have for Art Lovers and Urban Cyclists
For cyclists who love design-forward gear, or fans of limited-edition bikes, the Brompton x Shantell Martin P Line offers a rare blend of artistry, engineering, and collectability. It’s built to ride daily, fold quickly, and spark conversation at every stoplight.
