Brompton G Line Electric Folding Bike Traildust White Medium

Brompton 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.

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.

Brompton 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.

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.

The all-new one-bike solution for the city and beyond.

You can ride Electric G Line anywhere and take it everywhere.

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, mudguards, 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 boots.
Stores in small spaces (including one-person tents). In a world full of possibilities, Electric G Line is your one-bike route to everywhere.
