On snow and sand, yes, they are very much in their element and nothing else comes close. But on pavement, what's the point? No one in this discussion has been advocating in favor of fatbike tires, it's been about wide vs narrow road tires. In an ebike context, I'd call 28-32 narrow, 38-48 wide.

Any claim that wide tires as such do not steer accurately is just plain wrong.

I am a little slower on the trek overall too. I have debated on using the bulls wheels on the trek to really see how different the bikes work. but have been too lazy to get the parts to convert the hubs.
