Leo: Given the sentence "A shirtless man pulls back on his bike handlebars to do a wheelie on his bike." is it true that "The man is riding through the park."?

A shirtless man pulls back on his bike handlebars to do a wheelie on his bike is not necessarily doing it in a park.
Thus, the answer is it is not possible to tell.
