It’s a great, simple EV and my only knock against it is the slow max charging speed making it not ideal for multiple stop road trips.
Thankfully they're easier to DIY than an EV car.
Look at some of the cars of (say) the late-19thC where not even the steering wheel was standard. So, while e-bikes are probably not quite that early stage right now, they've not advanced terribly far from the plain vanilla bicycle yet.

Obviously very tailored for a nostalgic UK market, but if there's not equivalent companies in the US and elsewhere I'd be surprised!
You can sacrifice range of course.
Your 1967 Pontiac GTO sitting on Kragers isnt going to go very far on batteries.
Glad you wanna stay behind. Enjoy your horses.
