Description
Expertly engineered to go where others can't, the G Line 8 Speed Folding Bike is the first Brompton to deliver the ride feel of a full-size bike. With brand-new geometry, 20-inch wheels, and game-changing comfort and capability, it redefines what a folding bike can do. Every detail is designed around Brompton’s iconic fold, making it the perfect one-bike solution for the city and beyond.
The Brompton G Line is built for versatility and performance, featuring a range of innovations that enhance comfort, control, and durability.
Its solidly built 20-inch wheelset is large enough for any adventure yet compact enough to fit within the fold. Custom-made puncture-resistant tyres ensure reliability on varied terrain. Hydraulic disc brakes provide super dependable stopping power, making this the first Brompton equipped for all-weather, all-terrain riding.
The wide platform pedals offer exceptional grip and comfort, with the left-hand pedal designed for quick release to make the bike even more compact when folded. Custom-made wide handlebars deliver outstanding stability, whether climbing, navigating rough ground, or enjoying longer rides. Ergonomic grips ensure that every touchpoint between rider and bike is optimised for comfort and control.
The Brompton G Line is available in three sizes: small, medium, and large, based on rider height. Its single-size frame features different stem and seatpost heights, developed and tested with a world-leading bike fit expert to ensure the best possible ride experience.
