Survivorman (2005)

Season 1: Episode 7

The spectacular red landscapes of Utah's canyonlands are as beautiful as they are inhospitable. Like outlaws of old who were known to eat their own horses out of desperation in this forlorn place, Stroud will cannibalize the mountain-bike he has ridden into the middle of nowhere. As well as these scavenged bike parts to aid him, he also has a multi-tool, a magnesium flint-stick and an old energy-bar - that he has a use for other than eating.
