Isn't that pretty much what AZ, or at least some counties did? I'm not too current, but I thought I heard talk to that effect at the death race last spring, that Spooky tooth had helped get a more lax law passed for motorized bicycles. Mabye just in Bisbee? I'm not sure.
Wineboy, I wouldn't sweat the exact law if I was you. If the Tulie cops aren't stopping you, they must think you are legal. Sweet! I just lowered my speed to the fed limit because I want to lay low and not get motorized bikes kicked off the bike trail I depend on to get to work. So I lay on the spiel about the fed law to all who are interested. This also applies to the BLM mountain bike trails. So far 20 mph and the fed law is getting me the OK from the other riders on the trail to bring a motor. The signs say NO MOTOR VEHICLES, so I claim to still be a bicycle. But the state of NM still hasn't defined an ebike as a bicycle. It has defined a 2 wheel device with a low power motor as a moped though. Only a judge could really say for sure though. I'm pretty dang sure the way the statute is written, you put a motor on it, and you are some kind of motor vehicle, in this case a moped. But if they use horsepower at 50 cc levels as a measure of the size electric motor you could put on, that's at least 3000 watts or more.

8) Soooo, depending on how you read it, limit speed to 30 mh and you can run 100v.
One thing I learned though, if there is no law saying you can't, you can.
But laws can make a mess of it, when they disagree. Untill recently, you could sell an ebike in New York, and there was several shops in NY doing it. But they were totally illegal on the road. The fed law let em sell em, but NY law prohibited riding them except on private property.
