Only commuter and bikepacking bikes have mudguards, almost nobody puts one on a mountain bike or a proper road bike, regardless of whether they’re electrified. This looks like it’s more for these “sporty” categories of bikes.
That's a big blanket statement

I suspect this depends on the weather in your area - road cycling clubs near me often require mudguards for "winter club rides".
