Brompton G Line

The most capable Brompton ever.

The Brompton G Line goes where others can’t. Now you can confidently tackle everything from the city streets to singletrack trails.

Brompton G Line First Look

We tested the G Line over several days on our local streets and gravel tracks in South Wales. Check the video to see what we thought.

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.

Electric G Line

The Electric G Line is the most versatile e-bike in the world. Brompton’s all new compact electric system features a robust 250W rear motor and 345kwh battery offering riders 3 levels of smooth assistance when needed. Just like the G Line, the Electric G Line features larger 20” wheels, hydraulic disc brakes and wide handlebars.

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.
