I'm not sure how this is accessible, the drive-shaft is entirely customly designed and customly built to handle the torque. That's not even mentioning the 3D design software and laser cutting for the motor mount. This feels simple because he already has everything planned very well and it's a year long endeavour compactified into short youtube videos.

I don't see why 3D design software and getting parts fabricated (if you don't have the equipment to do it yourself) is all that inaccessible. It may cost more than getting into computer software, but just about everything is. It may not go very quick but there's nothing stopping you from doing this.

Heh, of course, I'm just taking the mickey out of myself. It avoids the car things that make me I'm know out of my depth: carburettors, gearboxes, firing patterns and such. Those come from a mysterious world I have no experience with.

If imagining a kit car then you won't be worrying about the custom designed elements you highlight.

The first time you mess up with a 90Ah pack and a serious electric motor will make you wish for carburettors.
