The box states that the Razor Crazy Cart is suitable for people ages 9 and up, but there will likely be some older ‘kids’ trying it out when the kids aren’t around. The Crazy Cart is a kind of battery-powered go-kart that allows you to drift it through a full 360-degree sweep at varying speeds up to 12 mph. It can even be made to spin like a top, if your stomach is up for such antics. On a full charge, the 24-volt battery allows the Crazy Cart to operate for up to 40 minutes before taking a 12-hour time-out to recharge. You can purchase the Razor Crazy Cart starting at $300 from www.razor.com.
