No word on when these might be coming to the USA, but it looks like Ninebot just released two new Segway-brand transporters in Asia (shipping there in September 2017). One is the "plus" we've already seen, and the other is a "lite" model for children and smaller people (with a shorter leansteer).

Notably the riders on the new units in the photos are multi-cultural and mostly non-Asian. Which makes me think they're getting ready for a worldwide launch--but starting with local markets first.
Also, it appears that Ninebot has already submitted the miniPLUS to the FCC--which is only applicable to the USA market. So I'm hoping to see the machine here for the holiday shopping season. In the $999-$1,299 range maybe?

P.S. Ninebot is also launching a new kids bike and traditional scooter--so if you're seeing those photos in the gallery just keep scrolling.
