A moped is a type of small motorcycle that is generally smaller and slower than a full motorcycle or automobile. Historically, the term "moped" referred to a vehicle with both bicycle pedals and a motorcycle engine, but now they are defined by their low-powered engine and step-through frame design. Mopeds typically travel only slightly faster than bicycles on public roads and 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. Most are similar to a regular motorcycle but with pedals and a crankset that may be used with or instead of motor drive.
Mopeds are generally less powerful than scooters, which have a more powerful motor and larger wheels. Mopeds are also typically slower than scooters, but they get better gas mileage. In some jurisdictions, low-powered three- or four-wheeled vehicles, including ATVs and go-karts, are classified as mopeds.
In summary, a moped is a small motorcycle with a low-powered engine and a step-through frame design that is generally slower and less powerful than a scooter.
