The DS-3 has a Hi-ten steel suspension frame that provides a fun and responsive riding experience. V-luxe 21-speed twist shift drive train and linear pull brakes upgrade performance, and the Kolo 5200 suspension fork and 3-piece crank are designed for and exclusively available on Huffy mountain bikes. Huffy Corporation manufactures mass-market bicycles. It was founded in 1887 when George P. Huffman purchased the Davis Sewing Machine Company and moved the factory to Ohio. Seven years later, in 1894, Huffman adapted the factory to manufacture bicycles. In 1949, Huffy became a common name after inventing training wheels for its Convertible Bike. From then on, Huffy made popular bikes, such as the Radio Bicycle, Dragster, Scout and Sigma.
