The Classic All-Steel Folding Bike. Original design refined for modern cities. 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 the 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).
The 3-speed steel bike with hub gear was the first Brompton made-a solid city rider built for the streets of London. The sealed gears are protected from grit, water and impact for longer life and less maintenance. Easy-to-use hub gears let you shift when stationary making the C Line Utility a solid choice for stop/start commutes, especially in wetter cities
