The Brompton P Line V2 12 Speed with Roller Frame refines the classic folding bike concept with lower weight, smoother ride quality and improved portability for everyday urban riding. Handbuilt using precision-drawn steel tubing alongside a titanium Superlight rear frame, it offers a lively and responsive ride while remaining compact enough to fold and store almost anywhere.
The updated frame design features a larger head tube and revised aluminium cockpit components for increased front-end stiffness and more confident steering. Combined with the one-piece carbon fork, the bike feels smoother and more composed over rough roads, broken tarmac and longer commutes. The carbon construction also helps reduce vibration through the handlebars for added comfort throughout the ride.
Its 12-speed drivetrain combines a 3-speed internal hub with Brompton’s direct-mount 4-speed derailleur to create a wide 402% gear range. This setup gives you plenty of flexibility for flatter city routes, stop-start traffic and steeper gradients while maintaining the compact practicality Brompton is known for. Ergonomic trigger shifters make changing gear simple and intuitive.
The lightweight wheelset and Continental Contact Urban tyres help the bike accelerate quickly while offering dependable grip and comfort on paved surfaces. Wider riser handlebars improve control and stability, particularly when manoeuvring through traffic or carrying speed across longer rides.
A major highlight of this version is the Advance Roller Frame, which improves the folded bike’s rolling capability when off the bike. Large roller wheels allow the folded package to glide smoothly through train stations, office corridors and shops, reducing the need to carry it continuously. The quick-release left pedal also helps minimise the folded size for easier storage.
Additional details like the Superlight saddle with integrated carry handle, ergonomic grips, bottle cage mounts and luggage compatibility make the P Line practical for everyday use. At around 10.6kg, it remains impressively light for a fully equipped 12-speed folding bike, making it a strong option for riders who combine cycling with public transport or need a compact bike that’s easy to live with day to day.
