Speed, Agility, Accuracy, Precision, Adeptness, and Clever Tactics
That is the reason why they won. The Mongols (cavalry) were known for their hit and fade tactics. Fire a shower of arrows, run, fire again. They will circle, fire, move. Run, lead them to a valley, where other Mongols would lie in wait and cut them off. Plus, China was "weak" in the sense that they weren't prepared for the Mongols and underestimated them. The composite bow of the Mongols had a pull of I think about 166 pounds, which was great in its day. The Mongols also had a longbow that was more powerful and had a bit more range.
