Brompton G Line Preorder - Nonrefundable Deposit

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.
