The Brompton P Line V2 4 Speed with Roller Frame is designed for riders who want Brompton’s famous folding practicality combined with lower weight, sharper ride quality and easier day-to-day portability. Handbuilt using precision-drawn steel tubing and a lightweight titanium rear frame, the P Line saves significant weight over the standard C Line while maintaining Brompton’s compact folding performance.
The updated frame design includes a larger head tube and refined front-end stiffness, helping deliver more precise handling and improved ride feel across busy streets and longer urban rides. Brompton’s self-aligning hinge clamps help the folding process feel quicker and more intuitive, allowing the bike to transform into a compact package within seconds.
A carbon fibre fork helps reduce weight while also improving vibration damping over rough roads and broken city surfaces. Combined with the redesigned aluminium cockpit and wider riser handlebars, the bike feels stable, responsive and comfortable whether weaving through traffic or cruising across town.
This version uses Brompton’s lightweight 4-speed drivetrain setup, which trims additional weight compared to the 12-speed model while still offering a practical range of gears for urban riding and rolling terrain. The direct-mount derailleur design keeps shifting smooth and efficient, while the 54T chainring and compact cassette provide simple, low-maintenance performance.
The Advance Roller Frame improves folded mobility significantly, allowing the bike to glide more smoothly when folded, making station platforms, offices and shops easier to navigate. Brompton’s large roller wheels and quick-fold design make carrying and storing the bike simple when space is limited.
Further premium touches include the Superlight saddle with integrated carry handle, ergonomic grips for improved comfort, and quick-release pedals that help reduce folded dimensions even further. The lightweight rims and Continental Contact Urban tyres keep rolling resistance low while maintaining dependable grip across city streets.
Weighing approximately 9.85kg, the Brompton P Line V2 4 Speed with Roller Frame is an excellent option for riders who prioritise lightweight portability, fast folding performance and a refined ride feel for commuting and everyday urban travel.
