Brompton P Line 4 Speed Mid Bar Folding Bike - Pacific Lacquer

Lightweight Performance. Refined Portability. Iconically Foldable.

Built for Fast-Moving Urban Life.
The Brompton P Line 4-Speed is a superlight folding bike engineered for riders who want all the practicality of a classic Brompton with an even more responsive, performance-focused ride. Hand built in Brompton’s London factory; the P Line combines Brompton’s iconic compact fold with advanced lightweight materials and premium components designed to move effortlessly through the city.

With a 2kg weight saving compared to the equivalent C Line model, the P Line feels faster to ride, easier to carry and more agile in every situation — whether you’re commuting, travelling or exploring beyond the usual route.

Superlight and Effortlessly Portable.
Designed for seamless everyday movement, the P Line folds down in under 20 seconds into Brompton’s famously compact package. The precision-engineered steel main frame is paired with a titanium rear frame and lightweight carbon fork, significantly reducing weight while maintaining the strength, durability and ride quality Brompton is known for.

From train platforms and office staircases to café stops and apartment living, the P Line makes carrying and storing your bike feel easier than ever. Large roller wheels and the integrated easy-grab saddle handle help the folded bike glide smoothly through busy spaces.

Fast, Agile and Responsive.
The superlight 4-speed drivetrain is fine-tuned specifically for city riding, delivering clean, intuitive shifting and a responsive ride feel with minimal complexity. The refined front end, carbon fork and upgraded aluminium crankset work together to create a bike that accelerates quickly, corners confidently and absorbs road vibration with ease.
Featuring Brompton’s 163% gear range with a 54T chainring and 11-13-15-18T sprockets, the P Line is perfectly suited to urban streets, rolling terrain and fast-paced commuting.

Premium Details. Elevated Everyday Riding.
Every detail on the P Line has been refined to enhance performance, comfort and portability. Ergonomic grips, lightweight aluminium handlebars, a superlight saddle and quick-release pedals all contribute to the bike’s dynamic ride feel and easy everyday usability.
Like every Brompton, it includes the front carrier block system for secure attachment of Brompton luggage and bags — making it as practical for commuting and errands as it is enjoyable to ride.
