Brompton Electric G Line 4-Speed
Electric G Line. The most versatile bike in the world.
The all-new one-bike solution for the city and beyond.
You can ride the Electric G Line anywhere and take it everywhere.
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.
Happily delivering on all sorts of surfaces. Confident in all conditions. Comfortable hour after hour. Electric G Line is expertly engineered to give you everything you need for the rough, the smooth and the beautiful. You can run a rack, fenders, and bags, add water bottles, and even store your toolkit inside the frame. And with the original Brompton fold, the ever-ready Electric G Line transforms into a compact, locked package in under 20 seconds. Goes on trains. Travels in car trunks. Stores in small spaces (including one-person tents). In a world full of possibilities, G Line is your one-bike route to everywhere.
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.
