2.
(intr) to ride a bicycle; cycle
[C19: from bi-1 + Late Latin cyclus, from Greek kuklos wheel]
1868, coined from bi- "two" + Gk. kyklos "circle, wheel" (see cycle), on the pattern of tricycle; both the word and the vehicle superseding earlier velocipede. Probably not from French, though often said to be. The
assumption apparently is because Pierre Lallement, employee of a French carriage works, improved Macmillan's 1839 pedal velocipede in 1865 and took the invention to America. See also pennyfarthing.
"That ne plus ultra of snobbishness -- bicyclism." [1876]
