The image shows a mountain biker riding a mountain bike on a trail in a forest. The biker is wearing a white helmet, a white jersey, and black shorts. He is riding a black mountain bike with a yellow and black frame. The trail is covered in dirt and there are red and white ribbons tied to the trees on either side of the trail. The trees in the background are tall and green, and the sky is overcast. The rider appears to be in the middle of a race, as there are no other riders visible in the image.
