Ernst Mach Ernst Mach Ernst Waldfried Josef Wenzel Mach (; ; 18 February 1838 – 19 February 1916) was an Austrian physicist and philosopher, noted for his contributions to physics such as study of shock waves. The ratio of one's speed to that of sound is named the Mach number in his honor. As a philosopher of science, he was a major influence on logical positivism and American pragmatism. Through his criticism of Newton's theories of space and time, he foreshadowed Einstein's theory of relativity.

Mach Rider and obstacles on the road. The up and down buttons are used to shift gears. Mach Rider's bike has four speeds and shifting to the fourth gear at high speed will grant the player in instant speed boost. Conversely, the player remaining in a higher gear while stopping results in a slower acceleration. In each round, points can be scored by destroying enemies and certain obstacles with the machine gun. The number of points scored for destroying enemies and obstacles is determined by the type of enemy or obstacle destroyed. If the player blocks an attacking enemy by ramming it
