What’s the difference between a scooter, a moped, and a motorized bicycle?
Even though the terms are used interchangably there is a quite a difference between scooters and mopeds. wiseGEEK.com‘s article “What is the Difference Between Scooters and Mopeds?” says that “The difference between a moped and scooter is found in the size of the engine and the power capacity,” but there are several differences between them. The line between them may be gray, but scooters and mopeds are as different as black and white.
First of all, the most obvious difference between mopeds and scooters is that mopeds typically have pedals on them that can be used to propel the bike. These pedals are also used to start the engine by engaging the clutch while the pedals are being turned or by turning them in reverse. In contrast, scooters usually have platforms in front of the rider that the rider places his or her feet on.
Scooters normally have smaller wheels than mopeds. Scooter wheels are generally 10″ (25.4 cm) to 16″ (40.64 cm) in diameter, whereas moped wheels are usually at least 16″ (40.64 cm) in diameter. Typically, mopeds have a smaller engine than most motor scooters. Moped engines are usually between 50 cc and 100 cc, whereas scooter motors generally range from 50 cc to 250 cc with some scooter engines being well over 400 cc. Scooter engines are usually mounted towards the back of the bike, typically on the rear swingarm. Moped engines are usually mounted on the underside of the frame near the rider’s feet.
The Wikipedia article on mopeds explains: “The earliest mopeds, introduced in the early 1950s, were standard bicycles with a helper motor in various locations, for example on top of the front wheel; they were also called cyclemotors.” These early vehicles were similar to what would now be referred to as a motorized bicycles, or motoredbikes.
Modern mopeds are designed to be propelled primarily by the engine, with the pedals being used only to start the engine. They can be used for propulsion in case of emergencies, such as engine failure. However, due to the weight of the vehicle, and the low gearing of the pedals, a moped being pedaled without engine power is often quite slow. Pedals are often only installed to comply with laws that require pedals in order for the vehicle to be legally recognized as a moped.
“Noped” is a term that is used to describe a vehicle that would otherwise be classified as a moped, but has been modified to have its pedals removed. Nopeds are popular in areas where the government does not require pedals on the vehicle for it to receive the legal benefits of a moped. (Photo of Yamaha QT50 Noped courtesy of Arman Bohn.)
Motorized bicycles, or motoredbikes,
are generally bicycles with an internal combustion or electric engine attached to it. Usually, the engine is an afterthought in the overall design of the vehicle, or it has been added as an aftermarket attachment. Several companies sell bicycle motors, whereas few companies sell fully built motorized bicycles.
The legality of these classifications of vehicles varies greatly around the world and within each country.
