I actually called the guys. They have a base price, and you can add 20 miles chunk of batteries for like 5 grand (that might have been for the car) and up to 8 or 10 5k chunks of batteries fit in the car. And they have a controller upgrade for a few hundred. Looks like they use several chargers at a time to get the times down or something.
$16k would be a nice write off, and look at all the advertising space on that two wheeler
Sorry, I can't get excited about a three wheeler though, have fun
