Definition of motorbike

"Motorbike" is a relatively recent term, emerging in the early 20th century. It's a combination of "motor" and "bicycle", reflecting its nature as a bicycle powered by a motor. While "motorcycle" was the dominant term, "motorbike" gained traction in Britain, particularly in the 1920s, likely due to its catchy and concise nature. It spread to other English-speaking countries, especially in informal contexts and when referring to smaller motorcycles. Today, both "motorbike" and "motorcycle" are widely used, with the former often associated with a more casual tone.
