The Brompton T Line Urban is the lightest Brompton ever made—an engineering marvel built for riders who demand portability without compromise. Weighing just 17.5 lbs, this ultra-light folding bike features a titanium frame paired with carbon fiber components including the fork, handlebars, crankset, and seatpost. It marks Brompton’s first departure from their iconic steel mainframe, pushing the limits of what a folding bike can be.

Made in London, every Brompton folds in under 20 seconds into a compact 24" x 24" x 12" package—small enough to store indoors, carry onto public transit, or take along on your travels. Despite its compact size, the Brompton rides like a full-sized bike, offering a smooth and stable experience.

To ensure smooth riding despite its small wheels, the Brompton T Line uses a large front chainring, optimizing gearing so you can maintain a comfortable cadence. This model features four-speed gearing, controlled with a simple and intuitive shifter. Two flat-bar style brake levers operate road-style caliper rim brakes for precise stopping power, with the right brake lever integrating a bell for added safety.

This model comes equipped with Schwalbe One Black tires, a lightweight, high-performance tire with a slick tread pattern designed for minimal rolling resistance while maintaining excellent grip. Full fenders provide all-weather protection, ensuring a clean and comfortable ride in various conditions. The included Brompton superlight saddle features carbon rails, a reinforced carbon base, and lightweight padding for added comfort on longer rides.

The Brompton T Line redefines what’s possible for a folding bike. Whether you're navigating the city, commuting, or traveling, this is the ultimate lightweight solution.
