Riding a bike has never been this fun. The Speed combines sporty performance with unbelievable value. The frame is hand-welded from custom-drawn 4130 chromoly Sonus tubing and incorporates six different patented technologies, resulting in what is probably our stiffest frame. It features the Dahon Neos rear derailleur, a revolutionary new design that has an ultra short cage for improved ground clearance and super fast shifting. We've paired the Neos with an 11-30T cassette, which, when compared with the previous 14-28T freewheel, represents a 37% increase in gear range. Sleek, simple and excellent value - just what most people want in a folding bike.
