3) This image contains a close up shot of the rear wheel spinning as well as a static chain, stem, and some of the front derailleur assembly. This image captures another moment in time that happens quite frequently when one is riding. Perhaps a cyclist has just climbed a large hill and is now starting the descent down, as he stops pedaling the chain remains somewhat still while the rear wheel spins at a very fast rate. This provides evidence that the cyclist is not moving the cranks and producing power, rather he/she is taking advantage of the machines ability to roll when acted upon by gravity.
