Motorcycles used to be one of the hottest means of transportation. With the development of society and the continuous progress of domestic economy, motorcycles are no longer popular. Even have banned on the road in many big cities. And gradually they have been eliminated by constantly improving the quality of life and scientific and technological products! Chongqing is a mountain city with great ups and downs. Bicycles and electric cars can't adapt to the terrain of Chongqing at all. Apart from public transportation, motorcycles are the most convenient ones. Motorcycles basically appear in the streets and alleys of Chongqing.
