In as much as I'm in the motorcycle aftermarket parts business (and I do quite well monetarily with it btw), I look at the Livewire as a 'Feel Good' vehicle, much like the Tesla. Both are cult vehicles for the 'greenies'. Problem is, both contribute to pollution, just not source pollution but the juice to recharge comes at the cost of stack emissions from power plants, radioactive waste from N plants and a tiny bit actually comes from renewable energy like Hydro, solar and wind, but very little.
The internal combustion engine will be around for a long time, certainly longer than I'll be alive and probably longer than most posters on here will live as well.
Ypu'll never find a plug in vehicle in my garage. Maybe a hybrid like a Prius but never an extension cord car or bike.
I think the Livewire is a 'feel good' experiment for HD and nothing more.
