Limited-Edition Art Collaboration Meets Performance Engineering
The Brompton x Shantell Martin Limited Edition P Line 4 Speed V2 is a rare fusion of artistic expression and premium folding bike engineering. This collaboration with world-renowned artist Shantell Martin MBE transforms Brompton's performance-oriented P Line into a rolling canvas featuring her signature black-and-white line art with pink accents. Made in small numbers for those who move differently through the city, this limited-edition model features a unique one-of-a-kind iteration of the Brompton logo hand-drawn by Martin, an exclusive laser-etched serial plate showcasing her signature work, and a premium saddle featuring her artwork. Beyond aesthetics, this is a P Line at its core—saving approximately 4.4 pounds compared to all-steel equivalents through titanium fork and rear triangle construction.
Handcrafted in Brompton's London factory, this bike transforms into a portable lightweight package in under 20 seconds, making it ideal for multi-modal commuting and compact urban living. The titanium components provide natural vibration damping for a smoother ride, while the proprietary Brompton 4-speed derailleur system delivers a 163% gear range with a fraction of the weight of internal hub systems. The P Line's refined geometry, Advance Suspension Block, and best-in-class components ensure responsive handling and fast acceleration through city streets. This collaboration invites you to draw your own line through the city—fluid, spontaneous, and entirely your own—while riding a bike that's as unique as you are.

Size Information
How Do I Know Which Size Brompton I Need?
Every 16″ wheel Brompton — C Line, P Line, and T Line — uses the same one-size frame. Your fit comes down to two choices: handlebar type and seatpost length. Between those two, a Brompton fits riders from 4′10″ to 6′4″.
Short on time? Mid handlebar + Standard seatpost works for most riders between 5′4″ and 5′11″. It's now the default on every new Brompton — and it's the default for a reason.
Handlebar Types
The handlebar determines your riding posture. All three fit the same frame — only the bar shape and stem height differ.
| Type | Riding Position | Best For |
|---|---|---|
| Low | Sporty, forward-leaning | Shorter riders wanting a natural position, or taller riders who like an aggressive, road-bike feel |
| Mid | Neutral, comfortable | Most riders — good visibility, easy on the wrists, great all-rounder |
| High | Upright, relaxed | Taller riders, or anyone who prefers a Dutch-bike feel with minimal wrist pressure |
Low — A flat, straight bar that sits about 3.5″ lower than the Mid. This is the lightest and most responsive option. If you're under 5′6″, it feels like a normal upright ride. If you're taller, expect a sportier tuck. One thing to note: only the Brompton S-Bag front luggage works with the Low bar.
Mid — Brompton's most popular handlebar. A curved riser bar that puts you in a comfortable, slightly upright position with great traffic visibility. If you're not sure which to pick, this is the safe choice.
High — The same bar shape as the Mid, just on a taller stem — about 2″ higher. Most of your weight sits on the saddle instead of your hands, which is easier on wrists and shoulders over longer rides. Riders under 5′5″ may find this position feels too upright.
Seatpost Options
The seatpost sets your saddle height. Getting this right matters — proper leg extension means comfortable, efficient pedaling and less strain on your knees.
| Seatpost | Inseam Range | Notes |
|---|---|---|
| Standard | 26″ – 33″ | Most compact fold — sits flush, fits all travel cases |
| Extended | 33″ – 35″ | Adds about 2.5″ of height; saddle sits higher when folded |
| Telescopic | 27″ – 39″ | Up to 7″ extra height, only 1″ taller when folded — great for tall riders and shared bikes |
How to Measure Your Inseam
Stand barefoot against a wall, feet about 6″ apart. Place a hardcover book between your legs, spine up, snug against your body. Measure from the top of the book spine to the floor. That number is your cycling inseam.
