G Line:  The most versatile bike in the world

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.

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.

The most capable Brompton ever

A closer look:

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 pedal with a quick squeeze and pull, the stow it securely behind you handlebar.

Wide Handlebars
Stay in control.  With the custom-designed handlebars, G-Line gives you exceptional stability - from leverage on uphiils 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 of 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 quiets vibrations and reduces pressure. 

The carrying 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, campers, an 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.
