Dahon, the folding bicycle manufacturer, has reported an increase in revenues of 36 percent to for the first half ended June 30, while volume deliveries went up by 27 percent to 180,000 units. The company attributes the increase to the consumer response to higher gasoline prices, greater environmental concerns and an increased sophistication in consumer tastes, particularly in the Netherlands, in China and in cities such as New York City and Chicago. With Dahon rapidly approaching its production capacity limit, the company is investigating alternatives for expansion and has started to ship products to Nissan, Volkswagen, Audi and Toyota to promote greater visibility and generate product tie-ins. To celebrate its 25th anniversary, Dahon has produced the lightest folding bicycle ever, the Mu XXV, due for limited distribution this month at Eurobike.
