The focus of this section of our guide is on motor scooters and motorized scooters, particularly the experience of riding them.

While both are referred to as "scooters," motor scooters and motorized scooters are not the same thing.

A "motor scooter" typically refers to a seated, step-through two-wheeled vehicle powered by a small internal-combustion engine or electric motor, with an engine size ranging from 50 cc up to 800 cc. On the other hand, a "motorized scooter," often referred to as an e-scooter, is a stand-up platform scooter powered by a hub motor (electric or gas) mounted in the front or rear wheel. Riders stand on a deck and steer via a collapsible handlebar.

They are both referred to as "scooters" because both designs feature low decks (foot rest platforms or standing decks), so mounting and dismounting require minimal leg lift. Both had narrow profiles, typically 8"-14" on motorized and 10"-16" on motor scooters, as well as upright ergonomics that facilitate curb-to-curb maneuvering. Most motor scooters employ a continuously variable transmission, while motorized scooters use electronically controlled motors; both eliminate the need for manual clutch and brake levers for shifting.

Motor scooters have a bench seat, often seating two, underpinned by a frame that integrates storage and fuel tank beneath and behind the rider. Motorized scooters are stand-only, folding for portability, and offer no integrated storage. Motor scooters are powered by internal combustion engines ranging from 50 to 800 cc or electric motors with a power output of 2-10 kW, reaching speeds of 30-70 mph and a range of 80-100 miles on fuel or battery. Motorized scooters utilize 250-500 W hub motors (either gas or brushless electric), achieving top speeds of 15-30 mph and ranges of 10-40 miles per charge. Frame motor scooters feature larger wheels (12"-16"), telescopic forks, front and rear shocks, and stamped-steel monocoque or tubular frames for enhanced stability at speed. Motorized scooters feature smaller wheels (8"-14"), minimal to no suspension, and lightweight aluminum decks.

Motor scooters utilize air- or liquid-cooled single-cylinder four-stroke or brushless electric hub motors, a CVT (automated belt), and a centrifugal clutch. The chassis features a steel bodywork with an integrated under-seat fuel and battery compartment. They use hand-lever brakes (hydraulic or drum), a twist-grip throttle, a foot peg, or a floorboard. Motorized scooters feature a front/rear hub motor with an electronic speed controller. The structure consists of a folding stem, an aluminum deck, and minimal guard or fender. They use regen braking, plus a mechanical disk or drum brake on the wheel. A lithium-ion battery pack, handlebar-mounted throttle, and brake lever power them.

The first motorized scooter was the Autoped, patented by Arthur Hugo and Cecil Gibson in 1915. It featured a 155 cc front-wheel engine, fold-down steering column, and 10" tires. It reached 20-35 mph.

In Italy in 1946, Piaggio introduced the Vespa, a monocoque steel-body motor scooter with a 98 cc two-stroke engine, CVT, and enclosed mechanicals for ease of use. Also in Italy, Lambretta followed in 1947.

While both are scooters, the evolution and realities of motorized scooters and motor scooters dictate that the former is more closely related to the non-motorized kick scooter, while the latter has a closer affinity with motorcycles.

Early kick scooters swapped human power for a tiny electric or gas motor, and left everything else the same, including the folding stem, standing platform, and minimal suspension. Motor scooters, on the other hand, essentially borrowed the drivetrain and chassis engineering of motorycles (engines, transmissions, suspensions), and repackaged them in a step-through monocoque or tubular frame with a lower center of gravity, an automatic clutch, and a wider floorboard.

Motorized scooters top out around 15-25 mph, and can travel from 10-30 miles on a charge, while motor scooters, with 50-300 cc engines or 2-5 kW electric motors, hit 30-60 mph or higher, and can travel 50-100 miles on a charge or a tank of gas, which is more in line with entry-level motorcycles scaled down for urban use.

In most jurisdications, motorized scooters require no vehicle registration or only a minimal power cap. In contrast, motor scooters typically fall under the rules for mopeds or light motorcycles, requiring plates, registration, insurance, and a motorcycle license; some jurisdictions offer specialized motor scooter licenses. In some jurisdictions, motorized scooters can be ridden on sidewalks or bicycle lanes, while motor scooters are restricted to streets or roads.

Motorized scooters and motor scooters share a sense of simplicity, but they are not the same thing.
