Add this to the list of things we wish was around when we were kids. The Actev Arrow Smart-Kart is an electric go-kart for kids 5-9 years old. It features two independent 250-Watt electric motors, a steel chassis, and can hit a top speed of about 12 miles per hour. It also has built-in WiFi and GPS, along with an app that allows parents to geo-fence kids inside a parent-defined boundary and control speed and safety. And if you pre-order, they’ll throw in a double capacity battery.
