Utility cycling encompasses any cycling not done primarily for fitness, recreation such as cycle touring, or sport such as cycle racing, but simply as a means of transport. It is the most common type of cycling in the world. In the Chinese city of Beijing alone, there an estimated four million bicycles in use (It has been estimated that in the early 1980s there were approximately 500 million cyclists in China). It generally involves travelling short and medium distances (several kilometres). It includes commuting, going to school, high school or college, making errands, and delivering goods or services. In cities, the bicycle courier is often a familiar feature, and freight bicycles are capable of competing with trucks and vans particularly where many small deliveries are required, especially in congested areas. Velotaxis can also provide a public transport service like buses, and taxicabs.
