I don't know why we have to have this conversation over and over again. Maybe save it for an ebike thread in General or Road?
I am not sure what motivation for the argument against calling an ebike an ebike. There is no confusion that there isn't a motor involved. Honestly, seems like trolling in this particular forum.
Having said that, there is no question that there are two wheeled vehicles powered by electric motors that aren't ebikes. I just learned yesterday that the Netherlands has another legal category that's faster than an ebike and has stricter requirements. I learned it because the police there now have treadmills where they can test how fast an ebike will go. There are 200 of them in the country.
