Digit (ru: Игрек / Igrek) is the smartest Fixie in Fixie School. He doesn't really have any friends, though.

Rather, he is a favorite of Grandpus, as he is proud of Digit.

Digit is the smartest kid in Fixie School, a great student that Grandpus is proud to have in his class! He seems to know just about everything about everything. Whenever you see him Digit is always in thought and he doesn't like to be distracted. Unfortunately he's always so busy figuring things out that he never seems to have time for just fooling around with the other kids and getting some exercise. That sure has made gym class a bit of a tough time. But he's so sweet that the other Fixie kids help him get through it. To tell the truth, Digit isn't always great at fixing things with his own hands, but no one understands technology better than he does and if something breaks, Digit can always figure out exactly what's wrong with it and the very best way to fix it.
