A generating apparatus includes an induction unit secured on a fixed mandrel of a bicycle, and a magnetic unit secured on a rotation member of the bicycle. Thus, when the magnetic unit is rotatable relative to the induction unit, the magnets of the magnetic unit are movable relative to the induction coil of the induction unit to produce a magnetic induction effect, so that the induction coil of the induction unit produces an induction electrical energy under action of the successive mutual interaction of the magnetic lines of force of the north poles and the south poles of the magnets of the magnetic unit to supply an electric power to the lamp of the bicycle so as to provide an illuminating function.
