Let's compare on and off-road performance and fun on the $2,000 Tesla Cyberquad for Kids versus $2,000 Segway Ninebot Gokart Pro! It seems the Cyberquad ATV four-wheeler is primarily made for kids (ages 8+), however it's less fun the older you get (Low power, torque, and max speed only 10 MPH). Unlike the electric GoKart Pro which is extendable in size for adults, carries up 220lbs, and max speed up to 23 MPH, it's insanely fun to drive!
