I could always trigger the light with a steel framed bike (and getting off isn't necessary), but half the time an aluminum frame motorcycle doesn't have enough ferrous metal to trigger a light (and trust me, there's more steel in the crankshaft than in any bicycle frame, it's just farther away from the sensor and encased in aluminum). A bicycle with a non-steel frame doesn't have a hope triggering a light with nothing but the bearings and races.
