Bit Bike

The Bit Bike (known as the Nanobike in Europe) is a small-sized bike in the game Mario Kart Wii. Its kart counterpart is the Booster Seat.

Stats
The Bit Bike has the best handling in the game. It also features great acceleration, off-road, and Mini-Turbo stats. Its drifting is average. However, it's the slowest vehicle in the game. Additionally, it's very light, making it easy for heavy vehicles to push it around.

When compared to the Quacker, the Bit Bike has a tad worse acceleration, but slightly better off-road. On the other hand, the Bit Bike is heavier than the Quacker, but lighter than the Cheep Charger.

Trivia

 * The Bit Bike is the only small bike, other than the standard bike, that drifts out.
