Many people like listening to the radio while taking morning exercise. So we have a new idea ROCKING RADIO utilizing the mechanical power that are produced by the exercise facilities to supply the radio work. Just clip ROCKING RADIO on the exercise facilities; it may automatically collect the energy for the radio when you are doing exercise.
It can satisfy the needs of listening to the radio while taking morning exercise.
