In the video, a person is seen working on a bicycle. The person is using a tool to adjust the brake of the bicycle. The bicycle has a red rim and a black tire. The person's hand is visible, and they are wearing a ring on their finger. The tool they are using is silver and appears to be a wrench or a similar type of tool. The person is making adjustments to the brake, possibly to ensure it is functioning properly. The background is not clearly visible, but it seems to be an indoor setting.
