You can choose for what cup you want to play, the time trail or the race. Then you can customize your rider, choose boy or girl, change the clothes or hair to your favorite style and when you earned enough points you can also upgrade from the bike that you start with to a horse, skateboard, inline skates and even a cow! There is also the option to change the colors and the controls used for the rider. Accelerate at the right moment for a turbo start! Once you do crazy stunts your nitro power meter will fill up and when it is full release it for a mega stunt!
