Bikes are popular in the Dutch（荷兰）. In fact, nearly half of all travel in the Dutch is by bike. Now, one Dutch bike designer（设计师）, Thomas, has taken the country’s interest in bikes by making a school bus bike.
The big bike has eight sets of pedals (踏板) for kids, a driver seat for an adult, and three other seats, comfortably letting little kids for their trip to and from school. The bike even has a motor, which can help with high hills or at times when few kids on it.
So far, Thomas tells Fast Company, he’s sold 25 school-hikes, at a price of $ 25,000 each—less than it would cost to buy a traditional school bus with the same number of seats. Along with  the traditional color, the bikes are colored yellow so that they can be seen easily.
Thomas says he’s sold school bus bikes to neighboring countries such as Belgium. England
and Germany, but so far, the school bus bike hasn't been sold in the United States. If the U.S. agrees to buy this kind of school bus bike, it could do a lot of good to improve exercise for a young age and help them keep healthy.
