so i am having questions about mopeds and motorized bicycles in Missouri. i have heard that in Missouri to ride a motorized bicycle you need a license. motorized bicycles are catagoried as being atleast 50cc. would anyone know if you need a drivers license to ride a motorized bicycle (moped) if the engine is under 50cc? i do not have a drivers license but i do have a permit and i would like to know if that would suffice for a moped under 50cc. i have found no answer for this question. thanks for your time all.
