A moped (/ˈmoʊ.pɛd/ MOH-ped) is a type of small and inexpensive motorcycle, generally having a less stringent licensing requirement than full motorcycles or automobiles. Historically, the term exclusively meant a motorcycle with bicycle pedals. Mopeds typically travel only slightly faster than bicycles on public roads.
Traditional mopeds are distinguishable by their pedals, similar to a bicycle. Some mopeds have a step-through frame design, while others have motorcycle frame designs, including a backbone and a raised fuel tank, mounted directly between the saddle and the head tube. Some resemble motorized bicycles, similar to modern ebikes. Most are similar to a regular motorcycle but with pedals and a crankset that may be used with or instead of motor drive. Although mopeds usually have two wheels, some jurisdictions classify low-powered three- or four-wheeled vehicles (including ATVs and go-karts) as a moped.
