The G Line comes equipped with mudguards and a roller rack set. Full-coverage front and rear mudguards help protect you from road spray, while the lightweight rear rack provides stable support for luggage or gear. Additional roller wheels on the rack make it smooth and easy to roll the bike when folded, whether on city streets or indoors.
Built for a wide range of riding adventures while still folding down to a compact size. The G Line features strong and durable 20-inch wheels with puncture-resistant tyres developed specifically for this bike, delivering stable and reliable performance for city commuting, gravel paths, and longer rides.
Stable and reliable braking power. The G Line is the first Brompton range to come fully equipped with hydraulic disc brakes, delivering strong and precise stopping performance when you need it, whether for all-terrain adventures or all-weather commuting.
Brompton’s grippiest and most comfortable pedal set yet. The left pedal can be removed with a quick press-and-pull mechanism, helping the folded bike become even more compact and easier to store or carry.
Stay in control across every kilometre. The G Line is fitted with wide handlebars designed specifically for this bike, offering greater stability and confidence whether climbing, handling rougher surfaces, or riding longer distances.
Every contact point between you and the bike has been carefully designed. The ergonomic grips provide more natural hand support, improve control, and help reduce fatigue on longer rides, making every journey more comfortable and relaxed.
The G Line is available in three simple size options: S, M, and L, making it easy to choose the most suitable size based on rider height.
The full range uses a single frame design, with different stem and seatpost lengths used to adjust the riding position. The sizing proportions were developed and tested with leading bicycle fit experts to ensure every rider can enjoy a natural, comfortable, and efficient riding experience.
We created the G Line as the ideal bike solution for both inside and outside the city, infused with the spirit of Brompton.
The G Line’s frame geometry delivers the stable and natural handling of a full-size bike, while still folding down in seconds into a compact and easy-to-carry form. It is designed to let you go wherever you want, whenever you want.
After more than 250,000 kilometres of demanding testing, the G Line not only meets industry standards, but exceeds Brompton’s own requirements.
It can go where other folding bikes cannot — from dusty off-road trails to rain-slicked cobbled streets, the G Line is built to handle it all with confidence and stability.
The G Line delivers a riding experience unlike any Brompton before it, with a newly designed frame, new 20-inch wheels, and Brompton’s widest-ever handlebars and tyres.
Every detail has been precisely engineered to create the ideal balance between off-road capability and city comfort, making every ride feel like a new experience.
