A minibike is a two-wheeled, motorized, off-highway recreational vehicle popularized in the 1960s and 1970s, but available continuously from a wide variety of manufacturers since 1959. Their off-highway nature and typically entirely off-road legal status differentiate minibikes from motorcycles and mopeds, and their miniature size differentiates them from dirt bikes.

The six main types of motorcycles are generally recognized as standard, cruiser, touring, sports, off-road, and dual-purpose. Scooters and sport touring are sometimes recognised as a seventh category, or integrated with the touring category in the case of the latter.
