I think that travelling is a good way to learning about the world. And I like very much. There are many kinds of transport to choose of when travelling. We may neither take a plane, a train, a bus, a car, a bike, a ship or even take a trip on feet. As for me, I prefer to ride a bike. There are a good many advantages of travelling by a bike. I suppose it is not only cheaply, but also help us take exercise. Compare with other forms of transport, riding a bike causes little pollution, and is better for the environment.
