The paper motorcycle designed by Nan Paper is based on the 1:1 reduction of Harley motor, and is the world's first 1:1 paper motorcycle. This paper motorcycle not only imitates Harley's tough mechanical lines and rugged shape, but also achieves realistic details of the shock absorption system, fuel tank, pedals, nuts and other particular characteristics. The charm of paper art lies in its infinite ability to express. These diverse expressions highlight the all-encompassing nature of paper art. By using the paper to bend and fold, the paper can be multi-angled, geometrically folded, and the surface effect can be supported at the same time, so that the three-dimensional shape of the flat paper transitions from thin to fragile.
