Brompton C Line 4-Speed Folding Bike

The Brompton C Line 4-Speed is the original folding bike, expertly handcrafted in London and designed for everyday city riding, commuting, and travel. Built around Brompton's iconic steel frame, it folds into a compact, secure package in under 20 seconds, making it easy to carry, store, or take on trains, buses, and in car boots.

Handmade in England since 1975, the Brompton C Line has earned its reputation as one of the world's most versatile folding bikes. Whether you're commuting to work, running errands, or exploring a new city, it delivers the perfect balance of comfort, portability, and durability.

New Brompton 4-Speed Drivetrain

The latest 4-speed drivetrain expands the C Line range alongside the 2-speed and 6-speed models, offering a wider gear range while maintaining the lightweight simplicity Brompton is known for. Originally developed for the Brompton P Line, the advanced gearing system provides smooth, reliable shifting for everything from flat city streets to rolling terrain.

The Advance Rear Frame enhances portability by allowing the folded bike to glide effortlessly on its roller wheels with the seatpost locked halfway, making it easier than ever to navigate railway stations, offices, airports, and public spaces.

Designed for Everyday Commuting

Built from durable steel with Brompton's signature suspension system, the C Line delivers a smooth, comfortable ride while remaining compact enough to fit neatly under your desk, restaurant table, or in a hallway cupboard. Powerful brakes provide confident stopping performance, while the compact fold makes multimodal travel simple and stress-free.

Compatible with Brompton bags, racks, and frame-mounted tool kits, the C-Line can easily adapt to your daily commute or even those weekend adventures!
