The most versatile bike in the world.
Coming 2025.
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.
We designed the all-new Electric G Line bike and e-system as one. Every element is meticulously engineered from scratch to work together in the city and beyond.
From brilliant on and off-road handling to easy charging and storing in small places, everything feels seamless with this bike.
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.
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.
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 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.
G Line comes in three easy-to-choose sizes based on your height. Small, medium or large. The single-size frame has varying stem and seatpost heights, developed and tested with a world-leading bike fit expert for the best ride experience.
