Price range: $5,000.00 through $5,300.00

The 2026 P-Line 12-Speed takes everything that makes the 4-Speed brilliant—and stretches it further. A steel main frame for strength, a titanium rear triangle for smoothness, carbon fork and oversized head tube for precision, and alloy contact points for weight savings. Together, they make a bike that feels fast, planted, and ready for distance.

With a new 12-speed drivetrain, it’s the widest gear range Brompton has ever built—perfect for hills, headwinds, and long rides that go beyond the city. Fast to fold, light to lift, and engineered to go the distance. Read our overview of the 2026 P-Line here.
