Although this video is about eSkateboards, the technology is the same for eScooters.
At least most eScooters these days are hub motors and don’t use chains or belts.
The video also contains, at the end, an eye-popping revelation about their referral program. That prompts me to remind people of my FTC Disclosure published at a past blog but which still remains in effect here. It hasn’t been updated because no one has since tried to graft me (don’t even try!).
