two young people riding bicycles on trainers

two young people riding bicycles on trainers. One is a boy wearing a white helmet, dark jacket, and black pants riding a black mountain bike on red and black rollers. Another person stands behind him and to the side. The camera moves to show a bald man in a black coat. Next, the camera moves to a girl with braids and an orange and white shirt who is also on a trainer. She is riding a gray bicycle. They appear to be in an indoor training area, likely for cyclists. There are tables and benches nearby.
