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.
