The Brompton A Line is a simple, practical, and affordable folding bike, designed for city riders who need a reliable and compact solution for daily travel. Built with Brompton’s classic handmade steel frame, this model retains the brand’s renowned durability and smooth ride quality while offering an entry-level option for those new to Brompton.

Folding in under 20 seconds into a compact 24" x 24" x 12" package, the A Line is easy to store indoors, take on public transit, or transport in a car. Its three-speed gearing provides versatility for urban environments, whether cruising on flat streets or tackling mild inclines. The mid handlebar delivers a balanced, upright riding position, making it comfortable for city commutes and leisure rides alike.

For stopping power, the A Line features flat-bar style brake levers operating caliper rim brakes, ensuring reliable braking in all conditions. The bike rolls on Schwalbe Marathon Racer tires, designed to offer a blend of durability and efficiency. Unlike higher-tier models, the A Line keeps things simple by forgoing the front carrier block, fenders and a rear rack, though these can be added later for extra utility.

The Brompton A Line (Mid Handlebar, 3-Speed) is an ideal choice for riders looking for an affordable, no-frills folding bike that retains the engineering and practicality Brompton is known for. Whether commuting, exploring, or simply needing a space-saving bike for city life, the A Line delivers a smooth and efficient ride at an accessible price.
