Not good, but has potential.
It has all of the problems that Mosfisk has already stated, and the controls are a bit hard. You could add more features, i.e. actual tricks, more control of the bike in the air, etc.

The gameplay is nice when you actually play. But there are a few things that you really need to put in there. Among many things, where is the "select level" button when you finish a level? I wanted to go back and check up on achievements but then I had to go to next or restart. Small things but oh so important.
