This will fail.
1. Harley demographic is entrenched, hard to pivot. Most associate with wealthy boomers and 'lowlifes', or working class murica. Not things as popular today. Other, better, performance ebikes exist, and outside this restrictive submarket, but are not thriving. And I will casually remind readers of Southparks opinion. That said, they do have diehard fans that would buy anything they made.
2. Motorcycles are all about freedom. Range issues, or even the idea of them, robs confidence. This will change, but gas is way more energy dense and on a bike it matters even more than cars. Going into the mountains is not when you want to wonder if your range will halve going up hills with gusto, or screwing it on for the corners.
3. Price perception. The electric will be awesome. Torque is so fun on bikes. But to harley riders, I think it will fell like a 'toy'. And for the price point, its gonna be a tough sell.
4. Tinkering. You do not buy a harley as an intelligent person without ever expecting to work on it. Hell, that is part of the classical appeal of them. There are more than a few explorations of life and motorcycle maintance in print. Maybe this is just my bias, but the connection with the machine is part of what makes motorcycling so intimate.
I very much welcome being incorrect. I shopped for an ebike and bought another used sportbike instead.
