Travel by Bike or Train
Many people, especially young people, like to travel by bike simply because it is convenient.
You can ride your hike whenever you like and go wherever you like to go. Besides, to travel by bike is
economical and does a lot of good to your health.
But still many people like to travel by train. They say it's faster and more comfortable to travel by train
over a long distance. Besides, it saves lots of their time.
In fact, both traveling by bike and traveling by train have their own shortcomings. By bike you can not
travel long distances and the speed is low. While traveling by train, you cannot go to the places where there
is no railway.
