Half of these rules are just opinions, and made me go looking for the affiliate links to figure out what they were trying to monetize. The rest of the article completely skipped any legal concerns other than saying they hope to ask a lawyer someday. But the line between an e-bike and a motorcycle is not fuzzy, it is clearly defined in your local regulations. It impacts where you can ride it, what license is required, and other such things.

Not that the article is all wrong - nearly half of it is good info, and probably will help people just getting into this arena.
