2025 Brompton G Line (Medium) – Traildust White with Roller Rack & Bag Included

This is a 2025 Brompton G Line folding bike in Traildust White, medium frame size, complete with the factory Roller Rack and a Small Borough Waterproof Roll Top Bag. The bike has covered fewer than 500 dry miles since purchase in October 2024 from the Brompton Junction Store in Covent Garden, and it's been stored indoors and meticulously maintained throughout. Everything runs flawlessly and it's ready to ride straight away.

The G Line moves away from the classic Brompton formula by fitting 20-inch wheels instead of the usual 16-inch, which changes how the bike rides and handles. It uses Schwalbe G-One all-round tyres and Tektro hydraulic disc brakes, giving genuine stopping power and stability that feels different from rim-braked folder alternatives. The larger wheel size means it's quicker on mixed terrain—city streets and light gravel alike—and it maintains momentum better over distance than smaller-wheeled folders. The 8-speed hub gears handle hills reasonably well without demanding constant attention.

What comes with the bike covers most bases. Beyond the integrated Roller Rack and Borough Bag, there's a Rhino soft carry bag (the bike fits inside with pedals removed), original wide platform quick-release pedals, Garmin Varia under-saddle light mount, front mount for Garmin, and all original paperwork and manuals. The condition is excellent across the frame, hinges, tyres and mechanical components, all showing minimal signs of use.

Brompton's lateral fold remains unchanged, so it still folds down to a compact size for train luggage racks or storage in tight spaces. The steel frame is robust and the build quality is consistent with what you'd expect from British-made Brompton engineering. Collection is preferred, though shipping can be discussed.
