A sound and illumination device including a sound-making portion, an illumination portion, and an attachment portion for mounting on a bicycle. The sound-making portion including a lever, a spring, a striking portion, and a metal portion, wherein the metal portion covers the lever, the spring, and the striking portion. The lever may include a magnet. The illumination portion including a cover portion, an electrical circuit, a switch, a light emitting source and a power source. Actuation of the lever of the sound-making portion results in the activation of the light emitting source of the illumination portion resulting in the concurrent emission of light and sound.

A rotating wheel and a balance scooter are provided. The rotating wheel includes a motor and an acoustic unit. The motor includes a stator, a rotor sleeved on a periphery of the stator and rotatable relative to the stator, and a motor shaft passing through the stator and defining a motor hole penetrating through the motor shaft. The motor hole is configured to receive a power wire and an audio wire. The acoustic unit is arranged on the motor shaft and electrically connected to the power wire and the audio wire.
