Brompton G Line with Roller Frame

Brompton G Line 8‑Speed with Roller Frame – Built for City Streets and Beyond

The Brompton G Line 8‑Speed is Brompton’s most capable non‑electric folding bike, designed for riders who want full‑size bike confidence with Brompton’s legendary fold. With 20" wheels, disc brakes, and an 8‑speed internal hub, the G Line handles city streets, waterfront paths, rail trails, and light gravel with ease — while still folding compactly for storage, transit, and travel.

Ideal for Ontario and Canadian riders who split their time between pavement and unpaved paths, the G Line delivers comfort, control, and versatility without sacrificing portability. Whether you’re commuting, exploring the Waterfront Trail, or loading a bike into a car or RV, the G Line adapts seamlessly.

Why choose the Brompton G Line 8‑Speed?

The G Line bridges the gap between a traditional bike and a folding bike. Its longer wheelbase, wide handlebars, and 20" wheels create a stable, confidence‑inspiring ride that feels familiar to riders coming from hybrid or gravel bikes. At the same time, Brompton’s precision folding system allows it to collapse in under 20 seconds.

The included roller frame lets the folded bike roll smoothly beside you — perfect for train stations, offices, and condo hallways.

Designed for Canadian riding conditions

• Stable handling on pavement, bike paths, and packed gravel

• Disc brakes for consistent stopping power in wet or variable weather

• Comfortable geometry for longer rides and mixed‑terrain routes

• Compact fold for GO Transit, car trunks, condos, and apartments

Free shipping is available across Canada, and test rides are available at our Burlington, Ontario store.
