I've ridden a number of EV motorbikes now, so I can tell you from experience that there are both good and bad points about the genre. How you ultimately feel about them will depend on your feelings regarding several things.
The TL;DR version is, if you commute frequently in stop-and-go small town or urban traffic, and you don't have to do a lot of battery-draining highway mile-munching, they're great. That's also assuming you find one you like at a price you're willing to pay, but that's another issue.
But the number of motorcycle OEMs that are thinking differently about the EV motorbike range conundrum has now doubled. First, there was Kawasaki and its Ninja 7 and Z7 Hybrids. And now, Yamaha's just introduced its new Series Parallel Hybrid Electric Vehicle technology with a short introductory video (in Japanese, but the diagrams are labeled in English).
