One way to get an electric vehicle is through converting an existing gasoline vehicle. That's the route taken by most EV owners today.
Wilderness EV offers a series of kits, and will also sell pre-converted cars using their kits.
What their kits offer are instructions, an electric motor, wiring, and a controller. It's up to you to find a suitable donor car, remove the gasoline related equipment, and install the parts. And once you install the parts you must find a set of batteries.
Their kit design uses a "shunt motor" which they claim to be superior to the "series motors" that are widely used in EV conversions today. I don't know enough about the differences to say which is best.
