Electric Bikes in the People’s Republic of China: Impact on the Environment and Prospects for Growth
ADB, SIDA, 2009. 94 p. ISBN:9715617932.
This report analyzes the environmental performance of e-bikes relative to other competing modes, their market potential, and the viability of alteative battery technologies. It also frames the role of e-bikes in the PRC's transportation system and recommends policy for decision makers in the PRC's central and municipal govements.
Electric bikes (e-bikes) provide low-cost, convenient, and relatively energy-efficient transportation to an estimated 40 million-50 million people in the People's Republic of China (PRC), quickly becoming one of the dominant travel modes in the country. As e-bike use grows, conces are rising about lead pollution from their batteries and emissions from their use of grid electricity, primarily generated by coal power plants.
