Good to know
Per DOR: 'A motorized bicycle does not have to be registered with the Missouri Department of Revenue.' A 'motorized bicycle' is a two- or three-wheeled device with automatic transmission, a motor of not more than 50 cc, producing less than 3 gross brake horsepower, and a top speed of not more than 30 mph on level ground (electric equivalency 2237.1 watts). Any moped/scooter (gas or electric) that does NOT meet these specs is classified and must be licensed/registered as a motorcycle. So registers=false applies only to qualifying motorized bicycles.

General guidance
Whether a moped or scooter needs a plate at all usually comes down to engine size and top speed — states draw that line in different places, and some skip registration entirely below a certain threshold. Pick your state below for the sourced answer.
Most states define a "moped" by a maximum engine displacement or top speed, and anything above that line registers as a motorcycle instead. The threshold differs by state — the state guide below states it where the agency has published it.
Some states require a full plate and registration for any moped operated on a public road; others require only a decal, a lower-tier registration, or nothing at all below the engine-size threshold. Check the state guide below for the real requirement.
A number of states let a standard driver’s license cover a moped, while others require a motorcycle endorsement above a certain engine size. This guide covers registering the vehicle; confirm license requirements with your state’s driver-license division.

States typically draw the line by maximum engine displacement or top speed. If your scooter is above your state’s threshold, it usually registers under the motorcycle process instead — see the Motorcycle guide.
