The Future of Folding. Electrified.

Meet the 2026 Brompton Electric G Line — the most advanced folding e-bike Brompton has ever made. With the integrated e-Motiq motor system, SuperRoll+ wheels, and intuitive handlebar control, this is urban commuting reimagined. And in Traildust White, it looks every bit as good as it rides.

e-Motiq Motor System

The G Line is powered by Brompton's e-Motiq system — a fully integrated electric drive unit that delivers smooth, natural-feeling assistance up to 15.5mph. The motor is seamlessly built into the frame, keeping the iconic Brompton silhouette clean and compact. Whether you're tackling a hill, pushing through headwinds, or simply arriving without breaking a sweat, the e-Motiq system has you covered.

SuperRoll+ Wheels with Roller Frame

The G Line features Brompton's SuperRoll+ wheels — larger 16" wheels with a roller-integrated frame design that makes folding and rolling the bike effortless. Push it through a station, tuck it under your desk, or stow it in the boot of a car — the G Line folds in seconds and rolls smoothly wherever you take it.

Handlebar Control

The dedicated handlebar-mounted controller puts everything at your fingertips. Switch assistance levels, monitor battery, and stay in control — all without taking your eyes off the road. Simple, intuitive, and perfectly integrated into the Brompton cockpit.

4-Speed Gearing

The 4-speed drivetrain gives you a versatile range for city riding — enough to spin comfortably on the flat and tackle steeper gradients with ease, all complemented by the electric assist.
