Brompton, G-Line eMotiq 4-Speed

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.

The most capable Brompton ever

Rigorously tested over 250,000 km, first to meet industry standards, then to meet ours, G Line goes where others can’t. Now, you can confidently tackle everything from dusty singletrack to rain-soaked cobbles. This bike does it all with ease.

Game-changing comfort

Nothing feels like G Line – the entirely new frame, all-new 20” wheels, our widest ever handlebars and tires. Everything is thoughtfully engineered to give the balanced feel of a mountain bike and all-day comfort that’s nothing short of joyous. You’ll feel the difference on every ride.

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.

Electric G Line. The most versatile bike in the world.

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.

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.
