ABSTRACT:
An electromotive scooter comprises an electric drive motor and a power source indicator that provides a visual indication when the electric drive motor is in the on condition. An electric circuit supplies electric current to an acoustic device, causing it to emit an acoustical warning, when the electric drive motor is in the on condition and a seat load sensor does not sense a load on the rider's seat.
