Electric motorcycles have this problem, too. Last year a popular German motorcycle magazine ("Motorrad") tested electric motorcycles in their big mountain test where they bring almost all available motorcycle models from that year to the alps.

The loudest motorcycle driven at normal speeds was an electric one.

I really hope they can bring that noise down further.

Was it loud because of EV drive or just the lack of ICE attenuated chain and sprocket noise further?

Looking at the powertrain:

It has to be either the planetary gear set or the chain - none of the gears are helical, so they're bound to be noisy. According to the specs the motor is a permanent magnet synchronous motor, which is normally mostly silent.
