Brand-new geometry, 20” wheels, game-changing comfort and capability. All holistically designed around the fold that made Brompton famous. Ride it, fold it, store it anywhere. G Line takes you there.

The all-new one-bike solution for the city and beyond. Big on ride feel. Compact in size. You can ride G Line anywhere and take it everywhere. Happily delivering on all sorts of surfaces. Confident in all conditions. Comfortable hour after hour. G Line is expertly engineered to give you everything you need for the rough, the smooth and the beautiful. You can run a rack, mudguards, and bags, add water bottles, and even store your toolkit inside the frame. And with the original Brompton fold, the ever-ready G Line transforms into a compact, locked package in under 20 seconds. Goes on trains. Travels in car boots. Stores in small spaces (including one-person tents). In a world full of possibilities, G Line is your one-bike route to everywhere. Equipped with a Shimano Alfine hub gear and available with or without the rear roller frame. The frame acts as the mount for rollers on which you can move the folded package.
