3．What is the most popular way to travel in the whole world，not counting a human being's two legs？You say by car？No．Train？Wrong again．Airplane？I'm sorry，but you're not even close．The most popular way of going from one place to another is by bicycle．And it is a surprise to most Americans．After all，we see thousands of cars each day．We don't see nearly as many bikes．
In the United States most bike riders are either young people or adults bicycling for exercise．About nine million bikes are sold in America each year．Nearly three million are sold to adults．The rest are to children．But in the rest of the world，far more people use the bike as their main way of traveling．They ride bikes to work，to school，and to stores．
Bicycles have been around for a long time-about 300 years．You would not like to ride around on those early bikes，though．They didn't have any pedals （脚蹬）．The riders had to push along with their feet．And this bike only went straight ahead．There was no way to turn the front wheel．If the rider wanted to change direction，he or she had to get off and move the bicycle．When pedals were put on the front wheels，riding became easier．The most popular kind of bike in the late 1800s had a very high front wheel and a small back wheel．It was a long fall to the ground!
Another problem was that there were no rubber tires （橡胶轮胎）．It's no wonder that one bike was called the"Boneshaker．"Then in the 1880s，air-filled rubber tires were put on the bicycle's wheels．Since then the bicycle has not changed very much．Of course bikes come in different shapes and colors now，but the main design is still the same．
