Expertly engineered to go where others can’t. G Line is the first ever Brompton with the ride feel of a full-size bike. Brand-new geometry, 20” wheels, game-changing comfort and capability. All holistically designed around the fold that made us famous. It's your one-bike solution to the city and beyond.
Rigorously tested over 250,000 km, first to meet industry standards, then to meet those of Brompton themselves. 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.
Nothing feels like G Line – the entirely new frame, all-new 20” wheels, Bromptons 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.
