I was riding my recumbent trike when all of a sudden, my air pump dropped off the left accessories holder. I had to walk back to get it, but it fell in a tunnel, and this being Taiwan, it ended up being rather dangerous.
Shot with the GoPro Helmet Hero WIDE, this video was rendered in HD so the titles look crisp.
BTW, I dropped my air pump on another ride but this time I couldn't go back and get it. A big truck ran over it.
