OK, apart from the poor audio, this annoys me a little bit (well quite a lot actually).
They say in the video they ‘cut out the middle man’, but wait … this scooter is just a rebrand of a ‘T9’ white label model that has been in the market for several years.
Here’s an almost identical scooter on AliExpress (which has a bigger 600W motor) and can be specified with a 13Ah battery and comes out at $859 US: https://s.click.aliexpress.com/e/_dZu3pBl (NB affiliate link)
So it looks like the main thing they customised was the branding! But hey, sure, I do actually love their deck decal, good job!
