Brompton G Line 8 speed with Roller Frame 2025 - Folding Bike
G Line
The G Line features an entirely new frame from Brompton, built around larger 20” wheels to offer a balanced feel of a full-size bike and all-day comfort. This new frame allows for more space allowing riders to fit racks, mudguards and bags for longer rides and adventures. It rides just like a full-sized bike, yet folds into a compact size for riders to store and travel with ease.
Larger Wheels
Big enough for any adventure, yet compact enough to fold with ease. The Larger 20” wheels roll over bumps easier offering a smoother more stable ride. The G Line's 20” custom-made, puncture-resistant tyres are also tubeless-ready, giving you the option for tubeless when you're ready.
Hydraulic Disc Brakes
Brompton's hydraulic disc brakes offer super dependable stopping power. The G Line is the first ever Brompton to come equipped with disc brakes for all terrain and all-weather riding. Uphill, downhill, rough, smooth, with luggage, in the rain, you can do it all on the G Line.
Wider Handlebars
Stay in control with the custom-designed handlebars from Brompton. These wider handlebars give you exceptional stability from leverage on uphills, control on rough ground and comfort on longer rides. They are also expertly designed to fit inside the fold.
Shimano Alfine 8-Speed Shifting
The G Line is equipped with the dependable Shimano Alfine 8 gear system that covers all terrain. It’s super simple to use and low maintenance, with just one trigger on your handlebars. The gears are tucked away inside your rear wheel hub, protected from impact and the elements.
