The Brompton Electric G Line SuperRoll+ represents the next evolution of folding e-bikes—powerful, versatile and purpose-built for modern city life and beyond. Designed as a fully integrated system from the ground up, the Electric G Line combines Brompton’s iconic compact fold with a refined e-Motiq electric drive system for smooth, confident assistance wherever you ride.

Built around a hand-brazed steel frame with full-size bike geometry, the G Line delivers exceptional ride quality while still folding into a remarkably compact package in under 20 seconds. The 4-speed drivetrain provides intuitive, low-maintenance gearing that’s perfectly matched to urban riding, mixed terrain and everyday adventure.

The SuperRoll+ roller rack and mudguards come fitted as standard, making the folded bike easy to roll through stations, offices and shops, while keeping you protected from road spray in all conditions. Integrated lighting, ergonomic contact points and hydraulic disc brakes ensure comfort, control and safety—hour after hour.

Powered by Brompton’s all-new rear motor and 345Wh battery, the Electric G Line offers responsive assistance with a real-world range of up to 45 miles (60 km). Smart handlebar controls, adaptive range estimation and the Brompton Electric app provide seamless control, regular over-the-air updates and future-proof performance.

Big on ride feel yet compact in size, the Brompton Electric G Line SuperRoll+ is a true one-bike solution—ready for commuting, touring, travel and everything in between.

Available now at On Your Bike London, Birmingham & East Grinstead.
