Main issue with electric motorcycles is that it still doesn't solve the safety issue of motorcycles, especially at freeway speeds.
At least e-bikes are locked at 25kph/mph. And can be folded into public transportation.
* Currently the predominant category of motorcycle riders are young males who ride like idiots (i.e. they are their own biggest cause of their own accidents)
* People driving 2 ton vehicles with their heads completely up their posteriors while driving. Fortunately those people are generally easy to spot and deal with.
If anything, more motorcycle riding will make the roads safer because you actually have to pay attention to what you're doing while riding. You can't shave, put on your makeup, or read text messages while riding. You actually have to pay attention! Also, motorcycle-on-motorcycle crashes are extremely rare outside of the context of group rides.
My biggest concern with e-bikes is people treat them like bicycles. I see people cruising around my neighborhood going 35 MPH on an e-bike without any safety gear on outside of maybe a bicycle helmet. The motorcycle safety culture of ATGATT isn't even on the radar of the e-bikers. Not to mention they don't seem to know the strategies of lane position, how to make yourself visible to others, how to swerve and brake quickly - which are all standard fare for motorcycle riders.
