The bike is based of the Bullet Bill enemies, combined with a box car. It is also the only vehicle in the entire game to not display the characters emblem on it. It can be considered to be the Bullet Blaster's successor from Mario Kart: Double Dash!!.
It Is also one of the three fastest starting bikes. Bullet Bike (with Baby Mario/Baby Daisy), Mach Bike (with Daisy or Mii) and Flame Runner (with Funky Kong or Rosalina). The Bullet exceeds in almost everything except for handling, acceleration, and off-road. It is one of the top three bikes for getting a good Time Trial record. It is, however quite low on weight, for instance, if you are going up a ramp and someone pushes you off, you may very well fall off from the course and have to get picked up. That is why it is better to be farther ahead than anyone else, and to avoid other larger characters, such as King Boo and Donkey Kong. Its kart counterpart is the Mini Beast.
