The kanji 騎 is a phono-semantic compound (形声文字). The left side is the radical 馬 (うま/uma), meaning "horse". The right side is 奇 (き/ki), which gives a phonetic indication and is associated with something unusual or special. Thus, the kanji depicts someone on a horse, with the horse being the main focus of the meaning "riding".
