People can sometimes get confused by the terms used to describe various forms of transportation. When a little boy, and a large gruff looking man in a leather jacket, both refer to a bike they are probably referring to something a little different. When motorcycles were first being built they were simply variations on the bicycles that were popular at the time. So when they first came out they were referred to as motorbikes. As the motorbike evolved it took on the name of motorcycle and that is where we are at right now with the terminology. However the term motorbike was never really phased out, it was simply shortened to bike and the term bike is now used to refer to both a pedal type bicycle and a motorcycle. So when you are using the term bike you can correctly be referring to two different things. However the one big difference between the two is that with the bicycle you do not need bike insurance to ride it, with the motorcycle you usually do need bike insurance before you can take it on the road.
