I stumbled upon a video in German that talks about retrofitting a Vespa into an all ev drive vehicle.
https://evo-retrofit.com/
They have a kickstarter project on there. I can see some people being interested in the kit and making their vespa all electric. I not sure I want to change mine to electric anytime soon.
Anyone who does convert to electric hopefully isn't doing it cuz of the environment but cuz they will get a better ride performance .
