Motorbikes are two-wheeled vehicles that come in a variety of styles. A MOPED is a type of motorbike that has a small engine and is designed for short-distance travel. It is usually restricted to a maximum speed of 30 mph and requires the rider to have a valid driver's license. A SCRAMBLER is another type of motorbike that is designed for off-road use. It typically has a higher ground clearance, knobby tires, and a more powerful engine than a MOPED. Scramblers are often used for racing and other recreational activities.
