It’s certainly one of the less obvious add-ons for the Wii. It really is an inflatable kart for kids, see below.

CTA Digital has launched their newest accessory for Nintendo Wii, an Inflatable Race Kart. This stationary Kart has a hard plastic steering wheel connected to the
dashboard which houses the Wii Remote. The seat is soft and comfortable and can support even up to 300 lbs. The Kart is 47 by 28 inches and is simple to inflate with any air pump via the air-valves on the sides.

The Inflatable Racing Kart is designed for kids to have fun, by letting them sit behind a steering wheel and feel like they are driving. Instead of worrying about the Wii Remote, children can maneuver their way through obstacles with precision using the MotionPlus compatible steering wheel.

With this Kart, children can sit in their make-belief car while playing their favorite racing games, including: Mario Kart, Need for Speed, NASCAR Kart Racing, and all other Wii racing games. Since it is inflatable, the Kart becomes portable and easy to pack up and put
aside if families want to free up space quickly.
