Ditch landings:
While going in a ditch, try making a smooth landing. Land on the downward side for special momentum, especially in Beat The Bird and Time Trial modes.
Extra points:
-Lose one or two lives on purpose when you are sure you can complete the final level or when on a level you are sure you cannot complete.
-Keep your front wheel up to gain points and increase speed.
Wheelies:
On the wheelie level, keep your bike as vertical to the ground as possible. This make your upper body parallel to the ground. Avoid leaning too far back to avoid falling. By doing this you will not fly forward after landing, and can continue your wheelie.
