Description

Brompton P Line 4-speed Folding Bike

The Brompton P Line 4-speed Folding Bike features a titanium rear frame and forks that are 700 grams lighter than all-steel equivalents, making it noticeably easier to carry, lift, and accelerate. Ideal for busy commutes and spontaneous leisure rides, the naturally shock-absorbing titanium smooths out uneven roads for a refined, comfortable feel. Its responsive handling and elegant design make city exploration faster, lighter, and more enjoyable, whether you’re weaving through traffic or cruising along quieter streets.

Purpose-built 4-speed gearing for the city

Designed in-house by Brompton, the superlight compact 4-speed gearing system is fine-tuned specifically for urban riding. Featuring an all-new 60-gram derailleur, the system is meticulously engineered to fit neatly within Brompton’s famously narrow fold without compromising performance. The result is crisp, reliable shifting and a perfectly judged gear range for flat routes, rolling terrain, and frequent stop-start riding.

Effortless folding with premium, everyday practicality

Folding down in around 20 seconds, the Brompton P Line 4-speed transforms into a compact, easy-to-carry package that fits seamlessly into trains, offices, and small living spaces. Finished with Brompton’s signature minimalist style and high-quality components, it delivers a ride that feels light, controlled, and rewarding every time. 

Handlebar options: 

  • Low: The straight handlebar. For a sporty, more forward position.
  • Mid: The riser handlebar. For a natural, relaxed position.
  • High: Riser bar with extra height. The ultimate relaxed cruising position.
