Brompton G Line 8-Speed Folding Bike – Big-Wheel Performance, Iconic Fold

The Brompton G Line 8-Speed brings the confident ride feel of a full-size bike to a folding design. With new frame geometry, larger 20-inch wheels and improved comfort, it offers more stability and control on city streets, rougher paths and longer rides, while still keeping the famous Brompton fold.

The bigger wheels and puncture-resistant tyres deliver a smoother ride over mixed surfaces, while hydraulic disc brakesprovide strong, reliable stopping power in all weather conditions. Wide handlebars, ergonomic grips and wide platform pedals improve comfort and handling, making everyday riding easier and more enjoyable.

Like every Brompton, the G Line folds down in seconds into a compact package that’s easy to carry, store or take on public transport. Combining full-size bike confidence with Brompton portability, the G Line 8-Speed is a versatile folding bike built for riders who want to go further.

Adventure-ready with the Brompton fold.

Big on ride feel, compact in size

Brompton created G Line to be the best one-bike solution for the city and beyond. The frame geometry is comparable to a full-size bike, yet it transforms into a compact package that stores and travels easily. So you can go anywhere.

The most capable Brompton ever

Rigorously tested over 250,000 km, first to meet industry standards, then to meet Brompton's, G Line goes where others can’t. Now, you can confidently tackle everything from dusty singletrack to rain-soaked cobbles. This bike does it all with ease.
