Tree attacks bike.
I wonder what happened to the cyclist. Probably got attacked by man-eating tree while enjoying a fantastic ride on that gentle path through the forest. Cycle heaved up with man attached. Man's meat and bones devoured by man-eating tree, leading to rapid growth spurt. Cycle, not made of meat, stays stuck in throat of tree, hanging like a trophy, warning all who go by of tree's man-appetite. "stay away" it says, "because men are scoundrel tree-fellers!"
