That hole is not caused by Chicago neighborhood celebrations. After careful photogammetric analysis it is determined that the aperture is exactly the same diameter of Captain Ahab's whaling harpoon. The bike was once painted white and ridden into to the peripheral vision of said whaling ship commander. Thus, triggering a synaptic eruption and hurling of harpoon.

This is proof of Meville's deleted passages referring to "shooting the moon with one arm tied behind me back". ARRGG!
