A bicycle dynamo for a bicycle having a frame and a wheel has a stator, an internal stationary winding fixed on the stator, and an external rotor rotatable on the stator. This rotor has a rotatable cylindrical external casing surrounding the winding and formed with an outwardly open annular groove, a plurality of permanent magnets inside the casing that generate an electrical voltage in the internal stationary stator winding, and an elastic ring frictionally engageable with a rim of the bicycle wheel, set in the annular groove, and projecting from the outer casing. A holder carries the stator.
