为何电动自行车欧洲受追捧?

　　New York Times: E-bike sales are now surging in Europe, especially in northern countries with long cycling traditions. For some markets, e-bikes have recently been the only area of growth.

　　According to the European Cyclists' Federation, there are 250,000 on the road in Switzerland.

　　In Germany, bike sales were down 5.5 percent last year, but sales of more expensive e-bikes were up almost 8 percent and now command about 11 percent of the market. In the Netherlands, which has Europe's highest per capita bicycle usage, the overall bike market fell slightly last year, but e-bike sales rose more than 9 percent.
