Description
Brompton P Line 4-speed Folding Bike with Roller Frame
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 easy to lift, carry, and accelerate. Titanium’s natural shock-absorbing properties smooth out bumps in city streets, providing a comfortable, controlled ride. Its responsive handling and sleek design make commuting faster and leisure rides more enjoyable, whether navigating traffic or exploring quieter urban routes.
Precision 4-speed gearing engineered for the city
Brompton’s in-house 4-speed gearing system is designed specifically for city riding. The new, superlight 60-gram derailleur fits perfectly inside the narrow fold without compromising performance. This ensures crisp, reliable gear changes and a practical range for stop-start commuting, rolling hills, and casual weekend rides, delivering both simplicity and efficiency for everyday use.
Roller Frame for convenience and stability
The integrated Roller Frame makes folded travel effortless, allowing the bike to be rolled smoothly alongside you rather than carried. It also offers extra carrying capacity and improved balance, ideal for commuters transporting work bags or leisure cyclists bringing essentials for a day out. Combining portability, performance, and smart practicality, the Brompton P Line 4-speed with Roller Frame is a versatile, stylish, and lightweight folding bike built for life in the city.
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.
