Location is everything. You have to look up your local legal statutes on mopeds/motorized bicycles/motor-driven cycles/motor-assisted scooter/limited speed motorcycle/motorcycle. If you don't know the statute(s) number(s) then you don't know the law. My state Tennessee statute is 55-8-101(35).
Simply putting operating equipment on the vehicle may not be enough. Some states in the USA don't allow any kind of self-built motorized vehicle to be operated on their public roadways. These places require vehicles to be made by a certified manufacturer. They generally post list of certified manufacturers every 90 days. Do your research and look up your local statutes.
You have already asked this same question Ad Nauseum in another thread you had already started and the responses have already shut down how you think you can try to make it legal by your sheer force of will.
not exactly a bicycle but soon I plan to build a minibike that has two 49cc engines on it so it will be legal to ride on the street but still have decent speed. What is the practicality of this? Thanks for reading

Im a retired police lieutenant and I will tell you once again what I told you on your other thread there is NO WAY IN HELL you can make that street legal or lawful or try to skirt it by any cop out there as being anywhere near breathing distance of legal.
I am now locking this thread since you already have an existing thread covering this exact same subject...Do NOT try my patience with this nonsense of twin 49cc pitbike motors in tandem and trying to think it is legal or using your flawed reasoning to think you could ever make it legal...Take it up with your law makers in your state as well as Federal Law.
I have a friend, (My landlords son in law), a GS-14 that works in D.C for that Organisation known as The National Highway Traffic Safety Administration (NHTSA), and I already know it is illegal on the federal level on what your totally convinced in your own mind could be made legal.
