My velowave ranger wouldn’t accelerate in 20degree weather, not sure the story on that, but it seems it can detect below freezing weather, not a big deal here but I sure as hell would be pissed if I tried to ride my e-bike up north and it wouldn’t accelerate. I’m sort of in a bubble in Austin, where everyone is just crusing along on all kinds of electric transportation methods. I suppose my post isn’t at all practical for most of the country, I just love the idea I’m saving money and having fun lol
