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). Geared up to go further: You can load this 6-speed all-steel workhorse with luggage and a rack for all-weather commuting or touring, then go explore. Some owners have cycled these around the world. Most use them to improve their day-to-day.
