We created G Line to be the best one-bike solution for the city and beyond, and then we made it a Brompton. The frame geometry is comparable to a full size bike, yet it transforms into a compact package that stores and travels easily. So you can go anywhere.
Rigorously tested over 250,000 km, first to meet industry standards, then to meet ours, G Line goes where others can’t. Now, you can confidently tackle everything from dusty singletrack to rain-soaked cobbles. This bike does it all with ease.
Game-changing comfort
Nothing feels like G Line – the entirely new frame, all-new 20” wheels, our widest ever handlebars and tyres. Everything is thoughtfully engineered to give the balanced feel of a mountain bike and all-day comfort that’s nothing short of joyous. You’ll feel the difference on every ride.
