because they have to travel through one place to another.

if a machine is not maintained properly,it will rust and cannot be used any more.

a bicycle is called a complex machine as it can be used as a means of transportation, used as a means of fun , exercise,etc.

suguan100: add this point it has two peddles, chain ,gear,handles,etc.
