A braking apparatus for stopping a children's kick scooter is described. The braking apparatus comprises a hand-held remote control to transmit a command signal when a radio-frequency (RF) signal transmitter is activated. The braking apparatus also comprises a remote control signal receiver located on the children's kick scooter to receive the command signal and convert it to an electric current. The braking apparatus additionally comprises a linear actuator to receive the electric current. The linear actuator comprises a linear actuator electric motor and a linear actuator shaft. The linear actuator electric motor is activated by the electric current and moves the linear actuator shaft from a first position to a second position. The braking apparatus further comprises a brake system to press a metal plate against a rear wheel of the children's kick scooter, thereby stopping the children's kick scooter when the linear actuator shaft is in the second position.
