A Brompton is one of the most portable bicycles, thanks to its three-fold design. This makes it the perfect urban mobility tool, but take the trifold beyond smooth pavement and you’re in for a rough ride. That’s why the British bicycle maker came up with the all-new G Line.

What does the G stand for? Looking at the photos, we can’t think of anything other than “gravel.” Brompton’s latest model is almost as revolutionary as its very first one with all the new features.

The biggest change is the 20-inch wheels covered in 2.1-inch Schwalbe G-One gravel tires. In the place of a Sturmey Archer internal-gear hub (IGH) is an eight-speed Shimano Alfine IGH with a range of 307%. Stopping power is provided by Tektro hydraulic disc brakes—another first for Brompton.

While the frame is still made of steel, the geometry has been revamped for a stabler ride, similar to a full-size bike. The G-Line is available in three sizes (small, medium, and large) to accommodate riders of different heights.

The stem and the fork are constructed from aluminum, and feature mounting points for accessories such as bottle cages. The G Line still uses the same front carrier block so it’s compatible with current Brompton bags and luggage.

Even the most casual of cyclists can appreciate the Brompton G Line. It combines the practicality of a trifold with rugged features such as thick tires and disc brakes, making it highly suitable for the rough roads of Metro Manila. The question isn’t whether we want one, but rather if we can afford it.

The Brompton G-Line will be available in three variants starting at £2,399 (P176,600). To get fenders and a roller rack, you’ll have to shell out £100 more for a total of £2,499 (P184,000). And if you want pedal assist, the Electric G Line costs even more at £3,499 (P257,600).
