This set guides children through the basic recognition of the parts of a mechanical system, helping them learn the various special uses of gears. By understanding how differently sized gears relate to one another, children will grasp the purpose of transmissions and develop an understanding of ratios. Using three-dimensional thinking, children will create models with various types of transmission and enhance their basic building skills.

The colorful guide contains various examples of gear combinations, from beginner models to more advanced ones. It includes many pieces, allowing children to expand their ideas, construct at the limits of their imagination, and build multiple models simultaneously.
