Big on ride feel. Compact in size. One-bike freedom for the city and beyond.
Introducing the G Line 8-Speed – the most capable and comfortable Brompton ever built. Expertly engineered to deliver the ride feel of a full-size bike, yet compact enough to fold in seconds and carry anywhere, the G Line sets a new standard for versatile urban cycling.
With brand-new geometry, 20” wheels, hydraulic disc brakes, and thoughtful comfort features, this is your one-bike solution for tackling everything from daily commutes to multi-surface adventures.
Whether you choose the version with roller frame for easy wheeling when folded, or the lighter standard model, the G Line is ready to meet you wherever the road leads.
The G Line is the first Brompton to deliver the handling and stability of a full-size bike thanks to its innovative 20” wheels and reimagined geometry. Yet in true Brompton fashion, it folds down in under 20 seconds into a compact, locked package that fits on trains, in car boots, or even inside a one-person tent.
You can take it anywhere – and ride it everywhere.
The G Line has been tested over 250,000 km to meet not only industry benchmarks, but Brompton’s own high standards. It’s designed to thrive on gritty city streets, rain-slick roads, gravel tracks and more — delivering unwavering performance, ride after ride.
Want to pack for an overnighter or long-distance tour? G Line supports bags, bottles, and toolkits — even integrates storage options inside the frame.
G Line is available in three sizes – Small, Medium, and Large – with a consistent main frame and tailored seatpost and stem heights. Each size has been developed with expert bike fit specialists to ensure optimal comfort and control for a range of riders.
Experience the G Line 8-Speed at any of our stores in London, Birmingham, and East Grinstead. Whether you're looking to streamline your daily commute or explore beyond the city limits, this is the most adaptable Brompton ever.
