It seems they "only" had $150,000 in funding, but as they were basically white labelling the Segway ES2[1] I'm surprised they didn't just hold onto their sales revenue to purchase the product...
Interestingly enough, about 2 clicks around their site and you realise they didn't even put the effort into setting up their Shopify site correctly... - https://unicornrides.com/collections/all
Playing devil's advocate here but the Shopify issue is because they removed the only products they sold on Shopify (that's why it 404s at /products/unicorn-scooter-product), that results in the collection being empty and that page showing up.
So their Shopify was likely fine until the business went under. Then they quite correctly stopped letting people make additional orders.
I’d rather they white-label the Segway than build the monstrosity in the video. Though the Ninebot won’t let you tote your three year old on it like in the video. (WTF? I know people do it, but advertise it as a feature? I ride a Boosted Rev to work every day, and my advice is: no one under 13 admitted, at all.)
Others in this thread are saying it was $700? Why not buy the Ninebot for $100 less? Or were the shipping models really going to have custom deck as in the video?
