Dahon"s Vector P8 combines the feel of a large wheeled bike with the size of a small wheeled one. It boasts Dahon"s light and lively hydroformed aluminum frame and fast-rolling Dahon 20-inch wheels. Up front, an aluminum Dahon fork steers the way. Plus, you get a precision-shifting 8-speed SRAM/Dahon drivetrain, powerful linear-pull brakes, corner-carving Schwalbe tires, and flat bars for awesome comfort.
