They are very quite and I've been watching videos of electric vehicles, bikes and a couple of snowmobiles and they are quite. But we really can't have a silent vehicle. So there has to be a trade off somewhere.
Here are some common sounds and that is why I have placed it around 60 dB, but it could lay closer to 50 dB as it is moving.
Rustling Leaves 20 dB
Whisper 30 dB
Wind @ 10 km/h 30 dB
Refrigerator Electric Motor Hum 40 dB
Light Traffic 50 dB
Normal Conversion 60 dB
Wind @ 20 km/h 62 dB
A really interesting article of now much noise an electric vehicle makes :
