No, this isn’t true. There is certainly variability in deck heights, and you’re right that the electrics tend to have higher decks because the batteries are often, but not always, in the deck. Even then it depends on the shape of the battery. And some electric scooters have the battery in the “neck” of the scooter instead!
Provisionally agree, we have the Xootr kick scooters with 180mm wheels and they work great! The M365 actually has even larger wheels at 8.5" or 216mm diameter. So I guess we’re good there?
That Xootr kick scooter I mentioned above is ~10-13 pounds, so we’re a little more than doubling that to get electric. And honestly that’s pretty good in my book! The 27 pounds of the M365 is OK. It would be nice if it was a bit lighter, but that’s at the lower end of the range as you can see here:
I think to get much lighter, we’d need next gen battery tech, beyond Lithium Ion. Which is damn exciting, considering how transformative Lithium Ion has been, I can only imagine what we’d unlock if we got 50% smaller, 50% lighter, 2× more powerful batteries!
I definitely agree that anything over 15mph isn’t necessary and gets dangerous. I do enjoy the briskness of the full 15mph on flat stretches though!
