Brompton G Line
A folding bike that deliberately gets bigger: 20-inch wheels, disc brakes and a more conventional ride, without abandoning the fold.
Traditional Brompton bikes optimize aggressively for compactness. G Line relaxes that constraint enough to change the ride: 20-inch wheels, hydraulic disc brakes, wider tires and an eight-speed drivetrain, all built around the company's familiar folding architecture.
Brompton lists the US model from 32.63 pounds and says the folded package measures 28.3 by 26.2 by 16 inches. That is no longer tiny by folding-bike standards, but it is still small enough to create a genuine transport advantage compared with a full-size bicycle.
What we know
What does the premium buy?
The rational baseline is either a smaller classic Brompton for maximum portability or a conventional full-size bike for ride quality. G Line's premium buys a rare middle ground: 20-inch wheels, hydraulic discs, wider tires and an eight-speed drivetrain while retaining a meaningful fold.
Best when the folding bike has to ride like a real bike
G Line is a rational premium for mixed-mode riders who want the fold but have outgrown the compromises of smaller wheels. Train-and-office commuters who prioritize minimum folded size should stay with a classic Brompton.
The catch
The same changes that make G Line feel more like a normal bike also make it heavier and less compact than the classic Brompton proposition.
