Pocketbikes are small, two wheeled recreational vehicles approximately one-quarter the size of a regular motorcycles, and are powered by two-stroke internal combustion engines of between 40 and 50 cc. Pocketbikes maintain the look of full-sized sport bikes and are known outside of North America for racing on specialty tracks designed for small Power Sport machines. These specialized models, designed for competition, produce up to 17 hp, and have front and rear suspension akin to larger sport bikes. Most consumer models are far less powerful, usually below 3hp, and do not feature suspension, relying on the tires alone for shock-absorption. Weight for most machines are approximately . The usual height is less than , and up to length. The popularity of these types of recreational machines originate from the introduction of Asian Imports to the North American market in late 2003. At the time costing as little as $200 US, these machines were unregulated, and many people believed they were legal for use as transportation on public roads. Pocketbikes variations have also been offered featuring four-stroke engines or electric motors, but these are far less common and are a derivative from the import market. Due to the diminutive size of the machines, and the origins of MiniMoto racing, Pocketbikes have been informally and inaccurately referred to as Minibikes. While the machines share certain attributes, Pocketbikes are more akin to sport bikes than minibikes, and are wholly their own machine by construct. The differences include frame manufacture and material, fairings, controls, engine placement and overall design. The misconception is likely due to two factors; The introduction of Pocketbikes into North America as inexpensive models not recognized for their intended competitive purpose, and being seen as toys rather than unique vehicles. The rapidness of law changes in the mid-2000s to remove previously undefined and unregulated Pocketbikes from public through-ways in American, due to safety concerns, lead to lawmakers hastily lumping Pocketbike in with Minibikes, Mopeds, and Motorized bicycle laws. Pocketbikes enjoyed a brief stint as recreational vehicles that did not receive citations when used on public roads, due to a lack of regulation. In North America, Pocketbikes have never been legal for use on roads and highways due to lack of safety features, height and visibility concerns. Laws are now in effect in most states and provinces to cite those that operate Pocketbikes on public through-ways or on public land. Due to the
