Sneakster

The Sneakster (known as Nitrocycle in the British English version) is a medium-sized hang-on type bike in Mario Kart Wii. It resembles a café racer, specifically a Moto Guzzi Le Mans. The character's emblem is located at the very back of the bike as well as behind the handlebars. It is unlocked by getting a one-star rank or better on all 100cc Wii Grand Prix cups or by playing 3,300 races. Its kart counterpart is the Sprinter. In addition, its large counterpart is the Spear in that both are the fastest and second heaviest bike in their respective classes.

Stats
The Sneakster is the fastest medium bike in the game (its speed can surpass that of the Sprinter by two points if ridden by Daisy, though it will still be one point below that of the Spear), tying with the Flame Flyer, a large kart. It is also the second fastest bike in the game after the Spear. In addition, it is tied with the Flame Flyer for the fourth fastest vehicle in the game, only being slower than the Sprinter (its kart counterpart), the Spear (its aforementioned large counterpart), and the Jetsetter (the Spear's kart counterpart). It also has average weight (tied with the Super Blooper) and drift (tied with the Bit Bike), but is actually the second heaviest medium bike in the game behind the Dolphin Dasher. Its other stats are quite low, and it has the worst handling, off-road, and mini-turbo of the medium bikes. Its acceleration is equivalent to that of the Shooting Star, Mini Beast, and Piranha Prowler, the last of which also has the same mini-turbo. Its off-road stat is tied with the Honeycoupe, the Blue Falcon, and the Wild Wing. The Sneakster also has the lowest stat total out of any medium bike in the game, having a mere 249 stat points.

Trading Card info
"If you take a look at the Sneakster's stats you'll notice one thing: awesome top Speed. It's one of the fastest in the game. Naturally, that Speed comes at a high cost, as all other categories have far lower stats..."
