Description
Brompton P Line 12-speed Folding Bike with Roller Frame
At the heart of the Brompton P Line 12-speed Folding Bike is a titanium rear frame and forks that are 700 grams lighter than all-steel equivalents, without compromising strength or durability. This makes lifting, carrying, and accelerating easier, ideal for commuters navigating stairs, platforms, and busy urban environments. The addition of the Roller Frame takes everyday practicality to the next level, making the bike more stable when folded and allowing it to be smoothly rolled alongside you through stations, offices, and cafés rather than carried.
12-speed performance for confident city riding
Brompton’s expertly engineered 12-speed gearing system delivers an impressive range while retaining the bike’s famously compact fold. Whether cruising flat city streets, tackling hills, or picking up speed in traffic, the P Line 12-speed provides precise, responsive shifting and total control. The redesigned suspension block maximises efficiency by transferring pedal power directly into forward motion. At the same time, titanium’s natural shock absorption smooths out the road for a comfortable, composed ride at any pace.
Roller Frame practicality with premium components
The integrated Roller Frame not only enables effortless rolling when folded, but also offers extra carrying capacity and improved balance - perfect for commuter cyclists transporting bags or leisure riders exploring new places. Paired with Continental Contact Urban tyres featuring Kevlar beads for reduced weight and Purgrip technology for reliable wet and dry grip, the P Line 12-speed with Roller Frame is fast, stable, and refined.
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.
