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.
- karolist 5y agoWas it loud because of EV drive or just the lack of ICE attenuated chain and sprocket noise further?

According to the specs the motor is a permanent magnet synchronous motor, which is normally mostly silent.
