Brompton C Line 4-Speed – Heritage Design, Refined for Everyday Riding

The Brompton C Line 4-speed is a versatile folding bike built for everyday riding, commuting and getting around with ease. With its classic steel frame, refined geometry and updated components, it offers the familiar Brompton ride with even more comfort, control and practicality. The 4-speed gearing provides a useful range for city streets and changing terrain, making it a reliable choice for daily journeys and rides further afield.

Like every Brompton, the C Line folds down in seconds into a compact package that is easy to store at home, take on public transport or keep at work. The front carrier block lets you carry luggage in a secure, balanced way, while the steel frame keeps the bike strong, agile and easy to handle. Hand-built in London, the Brompton C Line 4-speed is a practical and stylish folding bike designed to fit around everyday life.
