Source: Video Game / Need for Speed - Wii also introduced bikes, which couldn't charge up mini turbos to the same degree as karts, but popping wheelies gave a speed boost (at the expense of turning ability, which became practically nonexistent) and you would slow down a lot if bumped into while using a wheelie.
