Description
Brompton Electric G Line 4-speed Folding Bike with Roller Frame
Designed from the ground up, the Brompton Electric G Line Folding Bike integrates its 4-speed gearing system with a cutting-edge UK-engineered electric motor and battery. The robust rear motor delivers smooth, responsive assistance, while the handlebar display offers Smart features like Adaptive Range Estimation and Start Assist. Together, they make navigating stop-start city streets, hills, or longer leisure rides effortless. Over-the-air updates and smartphone app integration ensure your e-bike stays current, reliable, and tailored to your riding style.
Roller Frame and full mudguards for convenience and stability
The lightweight Roller Frame transforms folded travel, providing stability, extra carrying capacity, and smooth rolling over stations, pavements, or offices. Full-length front and rear mudguards keep you protected from road spray in all weather, while the bike’s frame accommodates racks, bags, water bottles, and even a toolkit. The 20” puncture-resistant tyres strike the perfect balance: large enough for comfort and control, small enough to fold easily.
Compact fold for effortless portability
Despite its powerful electric system, the Electric G Line folds down in under 20 seconds into a compact, lockable package that fits in trains, car boots, or small apartments, even one-person tents. Lightweight, versatile, and expertly engineered, the Brompton Electric G Line 4-speed with Roller Frame is a do-it-all e-bike that makes commuting faster, exploring easier, and every ride more enjoyable, rain or shine, city or trail.
