I've gotten into small electric vehicles lately:
- Ninebot ES2
- Ninebot gokart pro
- Ebikes (trek powerfly / liv / yuba / reise muller)
And I'm really interested in the `ninebot gt2`, but there's not really many good places to ride them around here, so I've started reading about how to build a small single lane go kart track.
- Small electric tractor with a digger arm on the front
- Large towable electric powered concrete mixer
And 5 friends and you could maybe build 100m of track a day on flat farmland (assuming its 1.5m wide). I think a 400m loop would make a great little race track. Maybe you add one or two passing lanes as well.
