Why should kids have all the newfangled fun? They shouldn’t! Quarter-life crises are on the rise, and those who can are spoiling their inner child with adult-sized Heelys and electric Mario Karts that can drift. [austiwawa] finally got his hands on a used Crazy Cart XL, and while it’s incredibly fun, the puny 500W motor doesn’t quite satisfy his need for speed. A 3x power upgrade should do the trick.

The new 1600W motor is considerably bigger, so [austiwawa] had to grind off part of the front fork to make it fit. He designed a replacement motor support plate and had it cut from quarter-inch steel. Of course, you can’t just drop in a crazy new motor like that and go — you need a battery and controller to match. A couple of attempts and a new spot welder later, [austiwawa] built a 48V battery pack out of 18650s. The cart actually weighs less now, which should make the ride extra insane. Put a helmet on FFS and drift past the break to the build video and demo. Then watch him tear up the mean streets parking lots of Canada and take the kart off some sweet jumps.

We love a good fun-mobile around here, be it scratch-built or hacked OEM. This wasn’t even [austiwawa]’s first rodeo — check out his water-cooled electric drift trike.
