Nothing feels like G Line – the entirely new frame, larger 20” wheels, our widest ever handlebars and tyres.
Everything is thoughtfully engineered to give the balanced feel of a full-size bike and all-day comfort that’s nothing short of joyous. You’ll feel the difference on every ride.
We created G Line to be the best one-bike solution for the city and beyond, and then we made it a Brompton.
It rides like a full-sized bike, yet it transforms into a compact package that stores and travels easily. So you can go anywhere.
The most capable Brompton ever
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 single track to rain-soaked cobbles. Built tough with disc brake stopping power, this bike does it all with ease.
