Brompton Electric G Line 4 Speed 2026 Folding Bike in Forest Green

Season:2026

Brand:Brompton

Code:2026EGGREEN

The Brompton Electric G Line 4 Speed was designed as a complete system, bike and e-system built together from scratch.

Rather than adapting an existing frame, Brompton's engineers started with a clean sheet, making every component work in harmony across city streets and longer mixed-terrain days out. The result feels seamless in a way that bolt-on electric conversions simply don't.

  • The most versatile e-bike in the world - Built from the ground up as one unified system, the Brompton G Line is engineered to perform in the city and comfortably beyond.
  • 20" wheels - Big enough to handle rough tarmac and kerbs with real confidence, yet compact enough to sit neatly within the bike's folded profile. Custom-made puncture-resistant tyres come as standard.
  • Roller Frame - G Line mudguards and roller frame are included from the off. Full-length coverage front and rear keeps road spray away on wet British days, the lightweight roller frame gives a stable platform for carrying cargo, and those extra wheels mean the folded bike rolls rather than needs to be lugged around.
  • Fine-tuned motor - Assist up to 15 mph for a quicker, more responsive feel on every ride.
  • Smart control - Handlebar display with Adaptive Range Estimation, Start Assist, and more, all within easy reach.
  • Built for real-world use - UL-certified for proven safety, with a rugged front carrier block and up to 50 miles of range.
  • Always improving - The companion app delivers over-the-air updates and new features, so the bike keeps getting better over time.

The whole system, rear motor included, was engineered in the UK. The battery has been rigorously tested for reliability and safety, and over-the-air updates through the app mean you stay current without needing a workshop visit each time something changes.

Among the best Brompton electric folding bikes available right now, the Electric G Line Brompton covers the bases that matter most to British riders: genuine range, proper weather protection, and a fold compact enough for the Tube, the train, or a car boot.

If you're looking at a Brompton folding bike that earns its place in daily life, the Brompton G Line electric bike in Forest Green is a strong contender. Available to buy now at Edinburgh Bicycle Co-operative, this is one of the most complete and well-thought-out Brompton electric folding bikes we stock.
