Dean Kamen must be sitting out on his private island asking himself "WTF???".
Fill the sidewalks with these and you could have your own startup!
Scooters go faster and have at least twice that range, I think.
I wonder what kind of wiggle room there is?
i would say the average athletic/fit person who is fairly lean (10-14% bf) [1] at a height of 6'0'' to 6'3'' will be anywhere from 165-205 lbs depending on frame, but very rarely more than 205 lbs
now there are definitely healthy and athletic and strong people who are at or above 220 at those heights but they will most probably be "overweight"[2] (have excess body fat) or on exogenous hormones enabling them to gain a lot of extra muscle mass (most bodybuilders, nfl players, college football players,etc) [3]

Even if the motors could (they probably can), heavy people would use more battery.
By the way, literally nobody said fat until you. We were talking about heavy people.
You'd need lean mass similar to Paulo Costa 6'1 https://i.imgur.com/ZBeIgGp.jpg to be a in a healthy body fat range if my napkin math is correct.
BMI is terrible except as a very quick "You really shouldn't be 35 on the BMI scale" sanity check.
Someone at 15% bodyfat and 6 feet, 1 inches tall can easily hit 220 pounds, if they have high muscle mass.
As another commenter pointed out, this isn't even considering the weight of clothing and carried items. My backpack usually weighs at least 15 pounds, sometimes up to 25. Clothes adds another, what, 3, 5, maybe even 8 pounds if I'm wearing boots?
At 193cm, with clothes, a backpack, laptop, i hit the 220lbs just so.
The BMI chart says someone should be 204cm tall for that weight to be the upper limit of healthy. Most charts don't bother extending this tall.
You know, the logical next step is a fleet of mechanical turk self-driving Segways. When the inconsiderate rider drops it off and blocks the sidewalk, just have someone take control over LTE+wide angle camera, and drive the Segway back to the nearest rental hotspot. Which could even have charging docks for the Segway to drive onto, like a Roomba.
Maybe now scooters actually will!
