I usually ride my ENGWE EP-2 Pro, but I have a Trek 820 MTB, skateboard, and I recently bought a ripstick because it was $4 at good will and I always wanted to try (I am bad at it btw)
Yeah, I had a battery issue where the charge doesn't show correctly and so far the support has been fucking awful: Very reminiscent of trying to deal with Creality support, which is also an absolute dumpster fire.
