Scooters, Mopeds, Etc... in Missouri

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:

  • 2 or 3 wheels.
  • Automatic transmission
  • Motor with a cylinder capacity of no more than 50 cubic centimeters.
  • Motor produces less than 3 gross brake horsepower.
  • Cannot have a maximum speed of more than 30 MPH on flat ground.

If your scooter exceeds the specifications above, it must be registered as a motorcycle, and requires a motorcycle license.


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.
