Brompton C Line Explore



The original design with the 3-part fold, handmade in our London factory since 1975. Compact and robust – it’s a seriously engineered bike that’s fun to ride.

Although C Line is made to stand up to the rigours of everyday life in the city, owners have taken them on around-the-world trips, on country tours and even to the South Pole, but mainly they are used 364-days a year to improve the day-to-day (we recommend a day-off for an annual service).
