Original just as if you walked into a bike store back in 1981. The only unoriginal part is the ear correct vintage Kenda rear tire. Most don't know this but BMX bikes have a larger front tire for reasons of steering. Rear tires were 20.175 and the Fronts were 20.2 and up. many people unknowing place the smaller tire up front thinking it is a hot rod automobile or something. Today BMX has went soft and front and rear tires are basically the same size today. The wheels we called them "Super Spokes" on account of the heavy gauge spoke and heavy steel rims.
