In the video, a person is seen holding a black bicycle seat. The person then proceeds to attach the seat to the bike frame using a black strap. The strap is secured with a black buckle, and the person adjusts it to ensure a snug fit. The bike frame is black, and the seat is also black, creating a uniform look. The person's hands are visible as they work on the seat, and they appear to be wearing a white shirt. The background is a plain wall with some writing on it.
