Your kid may not be old enough to cruise around in an Audi R8, but he can probably hold his own with the Audi Mini Runner. This scooter isn't powered by any motor but it is a convertible, in a certain sense. The scooter can go from a seated position to a standing one and features a handbrake for safety purposes.
The Audi Mini Runner is made out of aluminum in a process known as "hydroforming," so you can rest assured that this just isn't a normal aluminum scooter with Audi branding. The scooter isn't exactly as expensive as an R8 or TT Turbo, but it will set you back $450. You can't cut corners when it comes to starting kids down the path of brand loyalty.
