The Brompton P Line V2 4 Speed is designed for riders who want a lighter, faster-feeling folding bike for everyday urban travel. Handbuilt using precision-drawn steel tubing with a titanium Superlight rear frame, it delivers a lively and responsive ride while reducing overall weight compared to Brompton’s traditional steel models.
The redesigned front end improves steering precision and stiffness thanks to the larger head tube, updated aluminium stem and one-piece carbon fork. Together, these updates create a smoother and more controlled ride feel across rough city streets, uneven tarmac and daily commutes. The carbon fork also helps absorb road vibration for added comfort on longer rides.
This 4-speed version focuses on simplicity and low weight, using Brompton’s patent-pending direct-mount derailleur system to provide clean, reliable shifting with minimal fuss. The drivetrain is lighter than the 12-speed setup while still offering enough range for typical urban riding, flatter routes and rolling terrain. Ergonomic trigger shifting keeps operation intuitive and easy to use in stop-start traffic.
The lightweight wheelset and Continental Contact Urban tyres help the bike accelerate quickly while maintaining dependable grip and comfort on paved surfaces. Wider riser handlebars improve control and stability, especially when weaving through traffic or riding at higher city speeds.
One of the key strengths of the P Line remains its practicality off the bike. The folding mechanism is fast and compact, making it easy to store under desks, carry onto trains or tuck away neatly at home. Large roller wheels help the folded bike glide smoothly through stations and offices, while the quick-release left pedal reduces the folded size even further.
Additional details such as the Superlight saddle with integrated carry handle, ergonomic grips, bottle cage mounts and luggage compatibility add to the bike’s everyday usability. At just 9.85kg, the Brompton P Line V2 4 Speed feels noticeably lighter to lift and carry, making it an excellent option for riders combining cycling with public transport or navigating busy urban environments daily.
