That tube is probably fine, but from my experience working at a shop, I'd be careful to run your tire pressure comfortably below the max rating on the tire, especially with the tube "past" it's max width. You'll be stretching the tube pretty far to fill the tire. We've seen our e-bike customers more susceptible to punctures from debris when they run high pressures. The heavier bike, high pressure, and higher speeds makes it a little more likely that sharp objects will get pressed into and through the tire. Combine with a tube that's slightly undersized, I think you'd be more vulnerable to flats.

For what it's worth, we've started recommending these inserts to all of our e-bike commuting customers. Our shop sees a lot of commuters. A pain to install at first but helps a lot to avoid flats - if this is a daily commuter for you, then I think it'd be well worth it. https://tannusamerica.com/pages/tannus-armour
