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. It rides like a full-sized bike, yet it transforms into a compact package that stores and travels easily. So you can go anywhere.

Adventure-ready
The first ever Brompton with the ride feel of a full-size bike. Brand-new geometry, larger 20" wheels, game-changing comfort and capability. All holistically designed around the fold that made us famous.

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.

A closer look

Larger 20" wheels
Big enough for any adventure yet compact enough to fit inside the fold. The G Line’s solidly built 20” wheelset comes equipped with custom-made puncture-resistant tires. And if you’re looking for even more off-road performance and protection, they are tubeless-ready whenever you are.

Hydraulic disc brakes
Super dependable stopping power. The first ever Brompton to come equipped with disc brakes for all terrain, all-weather riding. Uphill, downhill, rough, smooth, with luggage, in the rain, you can do it all on G Line.

Shimano Alfine Hub Gear
A solidly built 8-gear system that covers all grounds. Super simple to use and brilliantly low maintenance. There’s just one trigger on your handlebars. And the gears are tucked away inside your rear wheel hub - protected from water, mud, and impact.

Wide platform pedals
The grippiest, most comfortable Brompton pedal set. For riding on all kinds of ground. And if you want to make your folded bike even more compact, you can remove the left-hand pedal with a quick squeeze and pull, then stow it securely behind your handlebar.

Wide handlebars
Stay in control. With the custom-designed handlebars, G Line gives you exceptional stability – from leverage on uphills and rough ground to comfort on longer rides. Expertly engineered to fit inside the fold.

Ergonomic grips
Every touchpoint between you and the bike is designed with comfort and control in mind. The all-new Brompton Ergonomic Grips are developed and tested by us for G Line, so you have the right cushioning and support exactly where you need it.

Brompton Superlight Saddle
Brompton-designed saddles enhance your ride and more. The Superlight Saddle carbon base quietens vibrations and reduces pressures. The carry handle under the nose makes lifting and rolling your folded bike even easier. And when it comes to adding Brompton Luggage or lights, the mount and loops are all in place.

Brompton engineering

A fold designed for life
From a go-anywhere bike to a compact package in under 20 seconds. It stores easily. Tucks in car boots and campers and even one-person tents. There is no need to lock and leave your G Line – it fits into your life indoors and out.

Moving with this folded bike is easy
Fold halfway. Steer with the saddle or tow with your handlebar. G Line stays locked together and glides like a wheelie suitcase. Breeze through train stations, along plazas and into buildings. Nothing folds like a Brompton folds.

Carry everything you need
Brompton Bags sit securely on the front of your bike with one quick click. The unique mounting system places the weight on your frame instead of the handlebars. So when carrying loads, your ride remains brilliantly stable.

Built tough
Built on fifty years of expertise, Brompton bikes are made for real life and a long life. G Line’s production is a labour of love, with each steel frame handmade and quality assured in our London Factory. With our 7-year frame warranty, you can ride with peace of mind.
