If you follow motorcycle racing MotoGp/WSB, when the director cuts to an onboard camera, you'll hear the revs rise as the bike is cranked over, the gearing has effectively been altered as the bike's on the edge of the tyre. The speed remains the same, but with an increase in engine revs, as the rear wheel diameter has momentarily become smaller.
