What Wiki says about mopeds: A moped (/ˈmoʊpɛd/ MOH-ped) is a type of light motorcycle designed to provide economical and relatively safe transport with minimal licensing requirements.
Mopeds were once all equipped with bicycle-like pedals (the source of the term, motor + pedal), but moped has been increasingly applied by governments to vehicles without pedals, based on their restricted engine displacement, speed, and/or power output. Mopeds occasionally resemble powered bicycles, but most are now step-through designs (of both kinds, having either large or small wheels) and step-over designs similar to a regular motorcycle.
Although mopeds usually have two wheels, in some jurisdictions low-powered three- or four-wheeled vehicles are also classified as mopeds.
In most countries, the legal driving age for a moped is lower than for regular motorcycles and cars. Mopeds are typically restricted to 45 km/h (28 mph) or 50 km/h (31 mph) from a maximum displacement of 49 cc (3.0 cu in), though there are a few variations.
In some countries, scooter motorcycles are sometimes called mopeds.
