What's soured me on electric scooters and bikes is the complete lack of repair infrastructure. My electric scooter was not cheap and when it broke (out of warranty) my local bike shop wouldn't touch it.
Which is why you buy from the local bike shop of the brand they sell.
My local bike shop will work on my ebike even though they didn't sell it, but it is a big brand that other bike shops in town sell so they see it enough and it is standard enough they can work on it. (I was given it for free, otherwise I'd have bought from the local bike shop). Bike shops will never work on the junk you buy at a big box store - the quality means it isn't worth it.
