Heads up
I went thru this earlier this morning with the Ohio BMV (bureau of motor vehicles) when I called my local office and talked to some of the little old ladies.
What we are doing here is putting motors on our bicycles. It's "installing a helper motor on a bicycle". It may be purchased as a KIT, or a homespun adaption "RAQUIMBILI" style. My state requires pedals so it so it can be peddaled under human power. Some states may not. WHEN YOU SAY....MOPED..... to those who don't know what we know.......yur opening a can of worms....that will eat your sanity.
Don't go there with Government bureaucrats. They will see/hear "Moped" and assume it to be what we here would know as a factory built moped like a Solex, Puch, Peugeot, or whatever. Then they will look for what you have on the state approved list. If you say it's a Schwinn bicycle with a Tas motor....it won't be on the list and they will tell you to take a hike.
Here is a brief list of laws, rules, and requirements State by State.

When I talked to them this morning after 1/2 hour I convinced them that this was a bicycle with a helper motor. It had pedals and I could ride it with the power off or out of gas just like a bicycle.(cause it was a bicycle) They kept wanting to go to "The LIST". I kept explaining I was in their web site...in the section for powered bicycles and explaining that if this was a real factory built "MOPED" I'd agree
to do so. So they kept saying that they would have to call in on the 1-800 number to which I told them that would be great as there would be people who understand this stuff there. Well, they didn't like the sound of my voice and wanted to know why a grown man wanted to do something like this anyways.
When I explained to Aunt Do-Do....that they get 200 miles per gallon.....I made a convert and she was wanting me to bring the thing by cause SHE had to see THIS !

I explained to her to imagine a weed whacker motor bolted up to a bicycle so it could run along at about 20 miles an hour and you could do your local errands on it and put stuff in the basket to carry home AND NOT BURN $20 DOLLARS WORTH OF GAS !!!!
So her last remark was......young man......when you come here just remember to bring your receipts/proof of purchase.

Oh..........gag and puke........I bought the bike in a flea market, and the "used motor only" (not all parts included) the same way.
I hope there's a full moon out tonight so I can go out and howl at it. And keep Aunt Do Do from sleeping.
GGGGRRRRRRR Bureaucrats !
