A motorized scooter (also gas scooter ) is a powered support scooter using a small utility gas engine or electric motor. These scooters are generally designed with a large "deck" in the center where the operator can stand. The first production scooter, "Sport" was released by Go-Ped in 1985. Recently the electric kick scooter has grown in popularity. This is considered by many different legislative bodies of motor scooters like the popular Vespa.

History
- 1915: Autoped introduces its stand-up scooter. Pulling back on the handlebar releases the clutch and applies the brake. Continued production of autoped until 1921; Krupp from Germany built the Autoped under license from 1919 to 1922.
- 1986: Go-Ped introduces the first production support scooter, "Roadster", which is soon followed by "Sport"
- May 2001: Go-Ped introduces the first full suspension electric scooter, "Hoverboard."
- 2004: Evo Powerboards introduces the first scooter with a two-speed transmission, "2x."
- November 2009: Go-ped introduces their first propane-powered scooter and go-kart, "GSR Pro-Ped" and "GSR Pro-Quad"
- 2013-2014: light electric folding scooters based on lithium batteries and brushless motor hubs become available.
- 2018: scooter sharing system without docking launched in major cities, largely as an extension of the bicycle distribution system.

Electricity
Electric kick scooters generally surpassed the popular gas-engined scooter since 2000. They usually have two small hard wheels, with folding chassis, usually aluminum. Some kick scooters have 3 or 4 wheels, or are made of plastic, or large, or not folded. A high-performance stunt shooter made for adults resembles a 19th century penny-fyhing, with a much larger wheel in front. Electric kick scooters differ from mobility scooters because they also allow human movers, and do not have gears. Reach usually varies from 5 km to 50 km, and a maximum speed of about 30 km/hour.
By 2017, some companies share bikes like LimeBike, and some scooter companies, such as Bird, start offering scooter sharing services with kick scooters.
Overview
Usage
In addition to its use for transportation, upright scooters can be used in law enforcement, security, or patrol.
Wheels and tires
There are two general categories of tires in which scooter travel stands - hard tires and air tires. Hard tires are generally six inches in diameter and are made of hard-plastic inserts surrounded by solid rubber tires. Air tires are most often 10 × inches in diameter. They are made of steel or aluminum split rim, inner tubes and rubber tires. Other, less common types of wheels and tires include 8 inch and 13 inch air tires.
Transmission
The most simple vertical scooter drive mechanism is the "spindle" drive. This propulsion mechanism puts an extension of the engine output shaft, spindle, in direct contact with the rear tire of the scooter. To function properly, the tire must have a clean, dry surface for the spindle to interact effectively. Scooters with this type of direct transmission can be pulled starting with the rear wheel of the ground or "bump" begins by forcibly pushing the scooter with the rear tire in contact with the ground.
Simple chain drive reductions are also used to transfer energy to the rear wheels of the engine. It generally combines a type of centrifugal clutch to allow the engine to be stationary independently.
Belt drive reductions use a wide and flat belt and pulley combination to transfer power to the rear wheels. Like a chain drive, belt drives include centrifugal clutch. Belt drives are more susceptible to damage in off-road conditions.
Suspension
The stand-up scooter suspension system ranges from simple spring-based fork systems to complex, wetted cam-link and suspension mechanisms of C.I.D.L.I.
Legality
- United States
In many parts of the United States, motorized scooters are not a street legal tool, because they can not be marked, titled, insured, and do not meet federal requirements for lights or mirrors. Certain regions may have further procedures that limit the use of motorized scooters. The highest speed of the average motor scooter is about 20 miles per hour (32 kilometers). Because their small wheel scooters are not usually safe to use on the road because even the smallest mounds can cause accidents.
California requires a person to ride a motorized scooter on the road should be 16 years of age or older, have a valid driver's license, wear a bicycle helmet, have no passengers, and otherwise follow the sames rules of the same road as the car. Motorized scooters must have brakes, may not have a handlebars raised above the operator's shoulders, and if driven at night should have headlights, taillights, and side reflectors. Motorized scooters can not operate on sidewalks or on roads if speed limits are installed more than 25 mph (40 km/h) except on Class II bicycle lanes.
