Brompton Electric G Line 4 Speed 2026 Folding Bike in Space Black

Brompton designed the all-new Electric G Line bike and e-system together, so every part works as a single package for city use and beyond. From sharp on- and off-road handling to simple charging and compact storage, the whole system is built to feel seamless on the road.

• 20-inch wheels, large enough for varied surfaces yet small enough to fold. Supplied with custom puncture-resistant tyres.
• Roller frame, fitted with G Line mudguards and roller wheels as standard, gives full-length spray protection and makes the folded bike easy to manoeuvre.
• Fine-tuned motor, offering assist up to 15 mph for a quicker, more engaging ride.
• Smart control, with handlebar display that includes Adaptive Range Estimation and Start Assist.
• Built for mixed surfaces and safety, UL-certified and fitted with a rugged front carrier block. Up to 50 miles of range depending on load, route and riding mode.
• The companion app provides over-the-air updates and added features.

The G Line electric Brompton balances compact folding convenience with genuinely useful range and stability when loaded. The 20-inch wheelset and roller frame make it straightforward to move the folded bike through public transport hubs or store it in small flats.

Adaptive Range Estimation gives a realistic idea of how far you can go with your chosen assist level and load. If you need a bike for commuting, mixed-surface rides, or light cargo, the Brompton G Line electric bike is a strong option.
