I was wanting to run a shift kit and be legal in Tennessee. Thanks for the reply.It depends on the state. NY is messed up, MaB are supposedly completely illegal there and NYC itself is known for confiscating ebikes
Most states don't have a plate for MBs unless you went through all the trouble to legally obtain a motorcycle or moped plate. Most states don't even have moped plates. In California it's really easy to get a moped plate, bike unseen by authorities (despite that, I refuse to plate mine).
Even if you were to have a friend set you up with a legal Cali plate for your bike, the dang things are illegal in NY state. Might make an interesting fight regarding right-to-travel perhaps, if one has the time.
