Nice project!

Did you know that instead of buying new motor controllers, you can re-use the hoverboard motor controller? Awesome people have made open source firmware you can flash to it: https://github.com/EFeru/hoverboard-firmware-hack-FOC. With this firmware you can make the motors go way faster, up to 40km/h with a 12S battery.

We are also building a kart with hoverboard motors, with a custom welded steel frame. Vibrations are a real issue with the standard solid rubber wheels, hopefully I can find the same air tires you used!

Our website is in Dutch, but you can watch the videos: https://projects.raphson.nl/projects/kart/
