G Line. The most versatile bike in the world.

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.

Big on ride feel, compact in size
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.
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 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 full size bike and all-day comfort that’s nothing short of joyous. You’ll feel the difference on every ride.

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.
