In MX Offroad Mountain Bike, you must drive your MX bicycle all over the course. You can choose the actual mountain trails, or you can take it "easy" and drive around the practice course to see how it's done. There's a very good chance you're going to crash. A lot. Arrow keys control movement. Up arrow for acceleration. Down arrow to brake. Left and right arrows to steer. Note: This game has advanced 3D graphics for an HTML5 game, and it has been known to crash a bit. If that happens, just reload the page and it should start out okay.
