Can Electric Bikes Provide Sustainable Transportation Solutions to Chinese Cities? An Investigation of Impacts on the Transportation System

Despite unprecedented motorization in China, most Chinese still rely on non-motorized modes. As a result of rising incomes and a long legacy of bicycle use, electric powered two-wheelers have risen in popularity over the past five years and the country has seen tremendous growth of this mode. Touted as environmentally friendly vehicles, they are capable of traveling about 40–50 kilometers on a single charge and emit zero tailpipe emissions. However, many cities are banning electric two-wheelers from city streets, citing safety and environmental problems. This research quantifies both the negative externalities (environmental and safety impacts) and positive mobility benefits of electric two-wheelers in China. Electric bikes perform well on most metrics, although their use results in much higher environmental lead emissions from battery production and disposal than any alternative. They do however provide unmatched, cost effective mobility and accessibility advantages compared to most alternative modes.
