The Brompton P Line Urban 4 is a high-performance folding bike designed for urban living. Its lightweight titanium rear frame is 700g lighter than standard steel equivalents, making it easy to carry, fold, and ride. The signature Brompton folding mechanism allows it to transform into a compact package, perfect for city dwellers or commuters with limited storage.
This model features a 4-speed drivetrain tailored for city riding, offering smooth and efficient gear changes to handle varying gradients with ease. The dual-pivot caliper brakes ensure reliable stopping power, while the Superlight wheels enhance agility and speed. The Superlight titanium fork further reduces weight without compromising durability.
Designed with comfort and usability in mind, the bike includes a dual-locking seat post for added stability when folded, and a front carrier block for additional practicality. The Brompton saddle integrates a rubber grip for carrying ease and includes mounts for a compatible rear light.
