We are ...
You are alone. Start it with "I are" or "we am".
You have zero evidence. What evidence do you need more?
I am not the only one to have asked.
But if you insist.
I are wanting you to tell me what evidence you would accept.
You won't accept pictures or Amazon listings where you can buy them yourself or my telling you I've ridden hub motor powered devices.
What will you accept? What kind of evidence would you allow?
