Has anyone had an issue in Pennsylvania with riding an MB on the road? I've searched the PennDot website and it's pretty vague. As far as I can tell, an MB is classified as a moped and requires registration and a license plate. The confusion lies in the fact that a MB cannot be titled, and you cannot register a vehicle that doesn't have a title. In PA, it's the equavelent of a dog chasing it's tail when it comes answers on riding these bikes on the street.
