The Brompton P Line Explore 12 features a carefully crafted lightweight frame, utilising a steel mainframe and a titanium rear section. This combination reduces weight by 700 grams compared to traditional all-steel frames, enhancing both portability and agility for city commuting. The frame’s responsive suspension block and superlight titanium fork further absorb vibrations, ensuring a smooth ride over uneven urban terrain.
Equipped with Brompton’s unique 12-speed drivetrain, this bike offers a broad range of gears while maintaining Brompton’s compact folding design. Engineered specifically for urban riding, the 12-speed system combines a 4-speed derailleur with a 3-speed hub, giving you versatile gearing without compromising the fold. The Brompton dual pivot caliper brakes provide reliable stopping power for quick manoeuvring in traffic or crowded spaces.
Its lightweight double-wall rims and Brompton tyres are designed for durability, supporting a quick and agile ride. The compact handlebars, foldable design, and larger 54mm roller wheels make it easy to manoeuvre the bike when folded, whether you’re rolling it through buildings or storing it at work.
