Brompton G Line - 8-Speed - Small - Standard Seatpost - Rear Rack - 20" Folding Bike - 2026 - Space Black

G-LINE - The most versatile bike in the world.

Expertly engineered to go where others can’t. G Line is the first ever Brompton with the ride feel of a full-size bike. Brand-new geometry, 20” wheels, game-changing comfort and capability. All holistically designed around the fold that made Brompton famous. It's your one-bike solution to the city and beyond.

Brompton created G Line to be the best one-bike solution for the city and beyond, and then they made it a Brompton. 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.

Rigorously tested over 250,000 km, first to meet industry standards, then to meet Brompton own, 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.

The Brompton folding system.

Invented in 1975 by Brompton founder Andrew Richie. Expertly engineered to transform the bike into a small, locked package a little larger than its wheels - all in under 20-seconds. Nothing folds like a Brompton folds.

Not like other bikes.

Brompton engineer an efficient solution for moving around the city and beyond. This is a bike that does more than the obvious, it answers problems owners say they didn't know they had. ‘You don’t get Brompton until you get a Brompton.

Each bike is hand-built and quality-assured at Brompton's London factory to cope with the daily demands of city riding. All Brompton bikes are powder coated in the London factory's in-house paint facility using environmentally friendly powders and energy from renewable resources powder coated.
