In New Zealand, "learner" and "restricted" motorcycles need only have a 250 cc engine capacity. This distinction draws some criticism, as it allows 15-year-old learner riders to operate bikes capable of reaching speeds in excess of 250 km/h.

The laws of some countries allow anyone with a car licence to legally ride mopeds not exceeding 50 cc in capacity, meaning that they do not need to show any competency in handling such a vehicle.

The laws and regulations for legal moped usage in the U.S. vary by state.^[18] The specifics of the motorcycle and moped laws in the U.S. can be obtained from each individual state's Department of Motor Vehicles' websites
