Who is the Brompton G-Line suitable for?

The G Line is built for riders who want Brompton’s iconic fold and practicality, with more comfort, stability, and power. Its 20” wheels and balanced geometry make it perfect for daily commuting, multi-modal travel, and weekend adventures alike.

Whether you’re riding to work, running errands, or heading off for a countryside escape, the G Line fits effortlessly into your routine — folding neatly for trains, flats, or car boots.

With up to 55 miles of assisted range and smooth hill-start support, it’s ideal for anyone looking to swap short car journeys for something faster, cleaner, and far more fun.

Design and Performance

Hand-built in London, the Brompton Electric G Line combines classic craftsmanship with next-generation technology. At its heart is the e-Motiq drive system, developed entirely by Brompton to deliver responsive, intuitive power that adapts to your ride.

The new handlebar control puts key information — battery level, range, speed, and assist mode — right at your fingertips. During your first 100 miles, the system learns your riding style and personalises its range predictions, so you always know how far you can go.

Smart Power, Seamless Control

Powered by a 250W rear hub motor and a 345Wh removable battery, the G Line offers up to 90 km (55 miles) of smooth, dependable assistance. The Start Assist function gives a gentle push up to 6 km/h to make hill starts and stop-and-go traffic effortless, while the torque sensor ensures perfectly balanced power delivery.

Hydraulic disc brakes provide reliable stopping power in all conditions, and integrated lighting keeps you visible wherever your day takes you. With app connectivity via Brompton Electric for iOS and Android, you can monitor performance, customise assistance, and stay up to date with over-the-air software improvements.

Built for Adventure, Ready for Everyday

The Brompton Electric G Line is made for everyday rides and weekend escapes alike. Its 20” tyres, hydraulic disc brakes and stable geometry give you control on any surface — from city streets to gravel paths. Compact, capable and confident wherever you take it.

Big on ride feel yet compact in size, the G Line folds down in seconds — meaning adventure doesn’t have to stop when the road does. From misty woodland rides to the city streets, it’s a bike that proves practicality and possibility can coexist beautifully.
