Difference between moped and scooter

A moped is a bicycle-type vehicle, equipped with pedals and a low-powered motor, which provides an economical mode of transportation. The term moped, or motor-pedal, is derived from the bicycle-like pedals that the rider uses to propel the vehicle and to start its helper motor. Most states classify a two-wheeled vehicle with a engine displacement lower than 49 cubic centimeters as a moped.  There are only two classifications of motorized cycle. Cycles with an engine below 50cc of power are considered mopeds. Engines that are over 50cc are considered a motor scooter even if they are not traditionally what one would think of a motorcycle. As far as manufacturing some makers will consider a moped a motor scooter even if it is under 50cc of power.

Mopeds are usually equipped with a pedaling system. Many states require this pedaling system. A number of mopeds can still be operated with only the pedaling system if necessary. Motor scooters do not have a pedaling system, they rely fully on the use of their electric or gas powered motor. Motor scooters also have foot wells to add protection to the operator.

In states where motor scooters are considered motorcycles, a helmet is required for any age of operator. For mopeds, in most states, a helmet is not required for operators passed a certain age. Additionally, a moped license can be acquired at an earlier age than a motor scooter license if the scooter is indeed considered a motorcycle.
