Where it begun ???
Arguably, the first motorcycle was designed and built by the German inventors Gottlieb Daimler and Wilhelm Maybach in Bad Cannstatt (since 1905 a city district of Stuttgart) in 1885. The first petroleum-powered vehicle was essentially a motorized bicycle, although the inventors called their invention the Reitwagen ("riding car"). It was designed as an expedient testbed for their new engine, rather than a true prototype vehicle.

However, if a two-wheeled vehicle with steam propulsion is considered a motorcycle, then the first one may have been American. One such machine was demonstrated at fairs and circuses in the eastern U.S. in 1867, built by Sylvester Howard Roper of Roxbury, Massachusetts.

In 1894, Hildebrand & Wolfmüller became the first motorcycle available for purchase. In the early period of motorcycle history, many producers of bicycles adapted their designs to accommodate the new internal combustion engine. As the engines became more powerful and designs outgrew the bicycle origins, the number of motorcycle producers increased.

The word moped was coined by Swedish journalist Harald Nielsen in 1952, as a portmanteau of motor and pedal. It is however often claimed to be derived from "motorvelociped", as Velocipede is an obsolete term for bicycle that is still being used in some languages such as Russian. According to Douglas Harper, the Swedish terms originated from "(trampcykel med) mo(tor och) ped(aler)", which means "pedal cycle with engine and pedals." (the earliest versions had auxiliary pedals).

Other terms used for low-powered cycles include motorbicycle, motorized bicycle, motor-driven cycle, and goped (motorized inline skateboard with T-bar). In German, the terms Mofa (from Motor-Fahrrad, "motor-bicycle") and Mokick (equipped with kick-start) are also used. In Finnish, the common term is mopo (from moottoripolkupyörä, "motor-powered bicycle"). The term noped is sometimes used for mopeds that do not have pedals.

Did you that...
Motorcycle fuel economy varies greatly with engine displacement and riding style ranging from a low of 29 mpg_-US (8.1 L/100 km; 35 mpg_-imp) reported by a Honda VTR1000F rider, to 107 mpg_-US (2.20 L/100 km; 129 mpg_-imp) reported for the Verucci Nitro 50 cc Scooter. A specially designed Matzu Matsuzawa Honda XL125 achieved 470 mpg_-US (0.50 L/100 km; 560 mpg_-imp) "on real highways - in real conditions." Due to lower engine displacements (100 cc–200 cc), motorcycles in developing countries offer good fuel economy.

In the Indian market, the second most selling company, Bajaj, offers two models with superior fuel economy: XCD 125 and Platina. Both are 125 cc motorbikes with a company-claimed fuel economy of 256 mpg_-US (0.919 L/100 km; 307 mpg_-imp) and 261 mpg_-US (0.901 L/100 km; 313 mpg_-imp), respectively
