C Line - Brompton Custom Shop - Base Model

Your Classic Brompton, Ready to Make Your Own This is the factory Brompton C Line—the starting point for designing a fully personalized C Line through our Custom Brompton Tool. Out of the box, the C Line is Brompton’s classic all-steel folding bike: durable, comfortable, and built to handle everyday riding with ease. In the Custom Shop, it becomes the foundation for whatever you want it to be. Use this base model to choose your drivetrain, bar style, lighting, wheels, touch points, colors, and premium finish options like Cerakote. Every component you select is installed and tuned by our Brompton specialists, so your final build is tailored to your riding style and ready for years of use. Whether you want a practical daily commuter, a weekend city bike, or a dramatic one-off creation. The C Line base gives you a trusted Brompton platform to start from. Begin your design, save as many configurations as you like, and build the C Line that fits you perfectly.
