Brompton
G Line / 4-Speed - Electric e-Motiq
We have one C Line (12 speed, Mid size in Dune Sand color,) and one G Line (8 speed, Medium size in Adventure Orange color) to view and test ride at the store. All bikes need to be checked for true availability, and then ordered by Rove Goods even though it states "1 item left in stock." Bikes take roughly 7-10 days to arrive here. Please call to check availability before ordering, as warehouse stock is currently in flux.

G Line / 4-Speed - Electric e-Motiq
One-bike solution to the city and beyond
Big on ride feel. Compact in size. You can ride the Electric G Line anywhere and take it everywhere.
G Line is the first ever Brompton with the ride feel of a full-size bike. Brand-new geometry, 20" wheels, game-changing comfort and capability.
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.
Powered to go places
Go anywhere in all weathers. With the Electric G Line's all-new 250W rear hub motor, you have superb stability and traction on all terrain.
With up to 56 miles of range and 3 assistance modes up to a maximum speed of 20mph, this motor and battery system is designed to help you go further without breaking a sweat.
Tested for durability, serious about safety
Designed with the same systems engineering approach found in the automotive and aerospace industries, the Brompton Electric sets the benchmark for quality and safety. Our bikes are independently certified to the
UL2849 standard, the most comprehensive e-bike electrical test out there.
Quietly intelligent
From the new and intuitive handlebar control to our first-ever fully synchronized app, with this bike everything and everywhere connects. Over the first 62 miles of riding, your Brompton Electric starts to build a good understanding of your riding style so it can make smart range predictions. Every 4 miles you ride it personalizes even further.
Handbuilt in London
Built on fifty years of expertise, Brompton bikes are made for real life and a long life.
Each frame is handmade and quality assured in our London Factory.
Experience the power of innovation
Brompton's all-new compact electric system, engineered from the ground up in the UK. Featuring a robust rear motor and a cutting-edge battery, rigorously tested for unmatched reliability and safety. Stay ahead with over-the-air updates and seamless integration with our bike app for your smartphone—designed to elevate your ride to new heights.
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.
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. C 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.
G Line sizes
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.
