I pride myself on searching for loopholes that benefit the consumer.
After a little research I found a few more things to consider: With my interpretation of the law about motor wattage, they are referring to how much power output the motor produces. Not how much power draw it has.
HB 727 says "an electric motor of less than 750 watts (1 h.p.)" The term horsepower is a term of output power.
Don't get this confused with what is labeled on an electric motor. When electrical products are measured for products of circuits for engineers to use, they often rate them as how much power they consume.
"Motor nameplates generally will show starting watts, some as high as nine times the running wattage."

No I'm not suggesting that the federal government is referring to the rated running wattage of the motor. However, they don't clarify it. I've also never seen a park ranger trained and carrying a multimeter rated for 1,000 consumption to properly test our bikes.
So that's why I'm interpretating the law as "produced power."
By themselves, motors don't produce any power. They need to be a part of a completed circuit to do that. So to properly measure the output of power that your bike produces you will need to include the battery being used, motor controls, and transmission. In other words, your complete bike and not just the motor.
The best realistic way IMO is to purchase a smart trainer that measures wattage output. Like the Bkool Smart Go for $400
However it can only measure up to 800 watts.
The cheapest way IMO to measure wattage output is by Strava.
Here is how to do it: Pick a level street and create a segment of 1/4 - 1/2 mile. Ride the the bike on full power and record. Ride it again with the motor off, preferably disengaged. Save the results on Strava and analyze them on a computer. Strava gives an output in power of each. Deduct your power from the ride that calculated both you and the motor and you should have your results.
The nice thing about Strava is that you can print out the third party results if you ever need to show proof in the court of law.
Make sure to always keep your label simple just like Amish David did. As of now it's the only thing the park rangers are looking for.
