In the video, a person is seen standing next to a bicycle. The person reaches out and presses a button on the handlebars of the bicycle. After pressing the button, the person then plugs a white cord into the bicycle. The cord appears to be a USB cord, which is commonly used to charge electronic devices. The person then begins to unplug the cord from the bicycle. It is unclear what the purpose of the cord is or what the button on the handlebars does. However, it is possible that the button is used to activate a feature of the bicycle that is related to the cord.
