A motor bicycle is a two wheeled motor vehicle with a single track. This is also referred as motorcycle, motorbike, bike, or cycle. Motor bicycle comes in various designs depending on the task like distance which needs to be traveled, navigating congested urban traffic, cruising, sport and racing, or off-road conditions. Motorcycles are descended from the "safety" bicycle, bicycles with front and rear wheels of the same size, with a pedal crank mechanism to drive the rear wheel. Motorcycles are small, lightweight; performance oriented motorized vehicles compared to other vehicles. This gives them certain advantages on the road in an emergency situation.
