Adult-sized children, rejoice. The Razor Crazy Cart , which we showed you way back in July of 2013 and which one fun-hating Autoblog staffer called "a pediatrician's nightmare," is now available for grownups. This is the best news you'll read all week.For those that need a refresher, the Crazy Cart is a fairly simple thing, riding on four corner-mounted castors with a single powered wheel under the steering column. This combination allows the sort of lurid drifts that would result in a very large accident were they attempted behind the wheel of a full-size vehicle.The sole downside of the original Crazy Cart was that was a tight fit for full-size humans and its top speed was limited by the extra mass behind the flat steering wheel. With the Crazy Cart XL, though, Razor has strengthened the frame and upgraded the electric powertrain with a larger motor and battery pack to accommodate up to 300 pounds and maintain 17 miles per hour. The drift bar, which lifts the central wheel, has also been upgraded to allow the Crazy Cart's wild slides. The result is arguably the most fun five wheels can provide.Prices aren't cheap, though, with the XL kicking off at $800. That's twice as much as the standard Crazy Cart. Of course, we simply don't care. All we want is to use one of these to scythe about the world's auto shows and use as a distraction when working from the Autoblog office. Scroll down to see the Crazy Cart XL and understand why we're so geeked about this wild toy.
