Of course, the bicycle has been around for more than 160 years and this isn't America's first bicycle passion. A wave of bicycle enthusiasm swept the land in the late 1800s and bicycle production was up to two million in 18917. Then with the coming of the automobile, bicycle declined, and for decades remained popular only with children and a few adults.
Now, a national concern with air pollution and physical fitness has brought the bicycle back to the forefront, particularly with adults. More than eight million bikes were sold in the United States last year, a third of which bought by adults. But the year before, only 15 percent of new bicycle sales were for adults.
