Add this $15 seat adapter to a $65 self-balancing scooter, and you've got a $80 electric car with about 20km range per charge and a quite high top speed. They say that it won't explode under you, and if you are a good driver you shouldn't end up under a car while using it. Beware though, it seems easy to accelerate to top-speed using this setup.
