This is a standing two-wheeled board from Kintone. By attaching separately sold parts, you can play with it as a go-kart! Includes box and instruction manual. The strap has been changed for safety (the included one uses Velcro, which tends to come off in go-kart mode). Please check the 4th image. Thank you for your consideration. #Kintone #Segway #Ninebot #GoKart #segway #StandingBoard #ninebot
