It is not too much to say that bicycle riding has many advantages. As it is,bicycles are not expensive so that every family can afford one. Besides, bicycle riding is especially good for health. It is good exercise. If you go to work by riding a bicycle instead of driving or taking a bus, you can have a better chance of getting enough exercise you need everyday. In addition,bicycling is also good for our environment. It is less noisy and does not pollute the air.In the meantime,it does save energy. And there is no denying that it is so convenient that we needn't wait for the bus,which in the long run gives us more time to do what we like.
As a whole,I take it for granted that bicycles are our best friends and play an important role in our daily life.
