Electric bicycles which run on battery-operated (电瓶) motors are winning over riders of ordinary bikes
41 their speed, quality and environmental advantage.
They were first
42 on 1980s in China, but the selling was not very good. Today, thanks
43 improvements on battery quality, the electric bikes sell well. There are now more than 100 electric bicycle producers in China and 26 million such bicycles were produced in 2011. Japan is another large
44 of such bicycles in the world with a total production reaching 381,721in 2010.
45 China is one of the largest producers of electric bicycles in the world, the
46 of its producers with mass production (大批量生产) is actually small.
Electric bicycles are still
47 in China. Time is needed for people to become familiar with them and accept them. Each bike’s price of between 2,000 yuan (US $318) and 3,000 yuan (US $477) is still 48 for ordinary citizens (民众). Although such bikes are quick, safe and
49 to operate, their batteries still have shortcomings (不足). They weigh more than 10 kilograms; their service life is
50 two years and they
51 400 yuan each.
There were more than 450 million bikes in China in 2006. If just one percent of all these bikes are replaced by electric
52 , the market will be very large. And
53 the battery is further improved and the price is
54 , many of us will not be able to keep back from
55 the latest electric bikes
