In the past two years,millions of Americans have suddenly taken an
interest in the bicycle as if it were a startling new invention.Annual bike
sales doubled between 1960 and 1970,and there are nearly 70 million bikes
in the United States today.That's more than two for every three
automobiles.
Of course,the bike has been around for more than 150 years,and this isn't
America's first bicycle boom
(兴旺).A wave of bike enthusiasm swept the land in the late 1800s and
bicycle production hit two million units in 1897.Then with the coming of
the auto,bicycling declined,and for decades remained popular only with
children and a few adults.
Now,national concern with air pollution and physical fitness has brought
the bike back to the forefront --- particularly with adults.More than eight
million bikes were sold in the United States last year and a third of them
went to adults.The year before,only 15 percent of new bike sales were for
adults.
