But the article from Digikey that you referenced says how much better it is to drive a “BLDC“ motor with sine waves.
That may be so but.. It also said how much harder and that it is seldom used.

"Sinusoidal control is complex and very few engineers can implement a system from first principles."

"Pure sinusoidal drive voltages are rarely used in practice because they are inefficient to generate for each motor terminal with respect to ground"

Both quotes from that Digikey link. So I'm doubting a BLDC scooter uses sine drive. And that is the thing that was being the topic, a BLDC scooter.
