Super Mario Combo biker
I think this is one of the hardest Super Mario flash bike games that I have played lately, yet I like it very much because it features a great number of good animated stunts that you can perform once you are launched off the ramp high in the air. The game has two available modes to choose from, "Championship" and "Time trial" where you must score the given amount by performing different tricks or and backflips. Hardest part of the game is to have a good landing once your perform is done but given the fact that all this happens at very high speed and high altitude you will see how difficult is to control your fall.
