The video shows a group of people riding bicycles in a race. They are wearing helmets and are riding on a track. The track is surrounded by a crowd of people who are watching the race. The bicycles are moving at a fast pace, and the riders are leaning forward to reduce air resistance. The track is made of wood, and there are barriers on either side to keep the riders from going off course. The crowd is cheering and clapping as the riders pass by.
