Often confused with each other, scooters and mopeds are quite dissimilar. Both are small motorised vehicles that operate on two wheels, but this is where the similarities end. So what is a moped, really, and why are scooters so different?
Defining the Moped

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 centimetres as a moped. Certain states, such as California, require mopeds to be equipped with pedals.
Scooter is readily identified by its step-through chassis and lack of pedals.
Motor-scooters, are distinguishable by their step-through chassis and footrest platform. They are typically powered by a small motor with displacements ranging from 50cc to 650cc. Scooters typically operate on smaller-diameter 10-inch wheels. Good examples of scooters are Honda's Spree, Yamaha's Vino, Suzuki's Burgman and the famous Italian scooters from Vespa.
Mopeds and scooters both use small motors for propulsion. However, a moped's motor is designed to assist the rider when pedalling and provides only a portion of the locomotive power. A scooter uses its motor to provide all of the propulsion, all the time. The scooter uses an electrical and charging system, which powers the lights and ignition system, as well as replenishes the battery. Mopeds may be equipped with a basic electrical system, but many can still be ridden by sole use of the pedals. Mopeds may use small or large diameter wheels, such as a 36-inch bicycle wheel. Scooters use only smaller-diameter wheels, the largest diameter being 12 inches.
Most states classify mopeds as motorised bicycles and do not require the moped to be registered. However, the rider must have a valid driver's license. Scooters are classified as a motorcycle, requiring registration, motorcycle-endorsed licenses, and in some states, insurance. Mopeds are generally restricted in speed and engine displacement, with most states limiting engine sizes to 49cc or less and maximum speeds of 30mph. Kansas, however, allows moped engine displacements up to 130cc. Scooters aren't limited in maximum speed or displacement.
Scooters and mopeds have long been entrenched in Europe's heritage, providing transportation to much of France, Spain and Italy. The moped moniker is commonplace and refers to many of the scooters and true mopeds that ferry people across many European cities.
