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).
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.
