I think a bike would struggle to have enough batteries packaged in there for reasonable range and speed.
That's going on using lead acids, like Anon. I've actually got access to hundreds of them, but like I say, packaging, what does 100Ah weigh, 35-40kg? It's a hell of a mass to lug about.
If I had to electrify something I would only do it to a kawasaki, curvy does not deserve that treatment
