The Brompton P Line 12-Speed SuperRoll+ is a lightweight folding bike designed for riders who want everyday versatility without sacrificing portability. Combining Brompton's compact folding design with a titanium rear frame, carbon fork and wide-range 12-speed gearing, it's a practical choice for commuting, city riding and journeys involving public transport.
The main frame is constructed from precision-drawn, heat-treated steel tubing with hand-brazed joints, providing a durable foundation for regular riding. It's paired with Brompton's Superlight Advance titanium rear frame, which helps reduce weight while retaining the strength needed for everyday use. The rear frame also features a replaceable derailleur hanger, making maintenance and repairs more straightforward.
According to Brompton, the lightweight frame construction saves approximately 700g compared with an equivalent all-steel design, while the P Line offers a weight saving of around 2kg compared with the original C Line. This makes a noticeable difference when lifting the bike onto trains, carrying it upstairs or moving it between journeys.
A one-piece Brompton carbon fibre fork further reduces weight while providing precise steering and helping absorb some of the vibrations encountered on uneven roads. Wider aluminium handlebars complement the refined front-end design, offering a comfortable and controlled riding position for navigating busy streets.
The P Line features Brompton's 12-speed drivetrain, combining a 4-speed external derailleur system with a 3-speed internal hub. This provides a wide selection of gears while maintaining the compact dimensions required for Brompton's folding mechanism.
Separate shifters control the external and internal gearing, allowing riders to adjust their pedalling effort to suit different terrain. Whether accelerating away from junctions, tackling hills or maintaining speed on flatter roads, the additional gear range makes the P Line more adaptable to varied routes.
The drivetrain uses Brompton's direct-mount derailleur arrangement and an 11-13-15-18T cassette, paired with a forged 6061 aluminium crankset and 50T chainring. The integrated chainguard helps protect clothing from contact with the drivetrain, making the bike practical for commuting in everyday clothes.
Brompton Dual Pivot Caliper brakes provide straightforward stopping power, helping riders manage their speed through traffic, approaching junctions and on descents. Their compact design also works neatly with the bike's folding mechanism.
The P Line rolls on lightweight 16in wheels featuring double-wall rims, double-butted spokes and aluminium hub bodies. Continental CONTACT Urban tyres provide a balance of rolling efficiency, grip and durability for everyday road riding, making them well suited to commuting and exploring city streets.
The smaller wheels contribute to the bike's responsive handling and compact folded dimensions, allowing it to be manoeuvred through tighter spaces and stored more easily than a conventional bike.
A Brompton Superlight saddle provides a comfortable contact point for regular riding, while its integrated nose handle offers a convenient place to grip when lifting or carrying the bike. Seatpost configurations vary depending on the selected handlebar height, with an extended seatpost on High models and a standard seatpost on Mid and Low versions.
Superlight quick-release pedals further improve portability, allowing the bike's width to be reduced when folded for easier storage and transport.
One of the standout features of this model is its SuperRoll+ system, designed to make the folded bike easier to move. The Advance Roller Frame provides improved stability and manoeuvrability, allowing the bike to be pushed or pulled through railway stations, offices and other indoor spaces rather than carried.
Combined with Brompton's compact folding mechanism, this makes the P Line particularly useful for riders who regularly switch between cycling and public transport. The bike can be folded into a compact package for storage at home, under a desk or in a car boot.
With its lightweight construction, versatile 12-speed drivetrain and improved folded portability, the Brompton P Line 12-Speed SuperRoll+ is well suited to riders who want a practical bike for commuting and everyday adventures. It brings together the convenience of Brompton's folding design with the additional gearing and refined components needed for varied urban journeys.
