Etymology 1

From Middle English cicle (“fixed length period of years”), from Late Latin cyclus, from Ancient Greek κύκλος (kúklos, “circle”), from Proto-Hellenic kúklos, kʷókʷlos, from Proto-Indo-European *kʷékʷlos (“circle, wheel”). Doublet of chakra, chakram, charkha, chukker, cyclus, kike, and wheel (see there for more).

Etymology 2

From -cycle (in bicycle, monocycle, and tricycle), perhaps associated with etymology 1. Compare French cycle in the same sense. The verb is either from the noun or a clipping of bicycle (verb).
