Instructions
Start any type of race or battle, but be sure to choose a bike when picking out your vehicle.
Accelerate to a fairly high speed as soon as the race starts, and wait for an opportunity where you have a long straightaway in front of you and few opponents and obstacles surrounding you.
Jerk the Wii wheel backwards towards your body. Your character will pop a wheelie, and your speed boost will start instantly. Be careful as you proceed, because your steering capability will be limited while your wheel is in the air and your bike will be more vulnerable to ramming by your opponents.
Jerk the Wii wheel forward, away from your body, when you want to put your front wheel back down. If you do not do this for several seconds after initially going into a wheelie, your character will automatically drop out of the wheelie.
