Scooters and Mopeds

Scooters and mopeds, if they fall under the category of "motorized bicycle," don't have to be registered. Missouri DMV officially uses the following criteria to define a motorized bicycle:

• Two or three wheels.

• Automatic transmission

• Motor with a cylinder capacity of less than 55 cubic centimeters.

• Motor produces less than three gross brake horsepower.

• Cannot have a maximum speed of more than 30 miles per hour on flat ground.

If your scooter can travel more than 30 miles per hour or has a cylinder capacity of more than 55 ccs must be registered as a motorcycle, and requires a motorcycle license.

Registration, Licenses, and Helmets

While motorized bicycles don't have to be registered, you do need a valid driver's license to operate one. Currently, Missouri law doesn't require helmets, but it's always better to be safe than sorry. Some local or municipal laws have different helmet requirements, so be sure to check.
