A bicycle chain is a chain that transfers power from the pedals to the drive-wheel of a bicycle thus propelling it.

The chain in use on modern bicycles is a roller chain with a 1/2" pitch. Chain comes in either 1/8" or 3/32" widths. 1/8" is used on the common low cost coaster, three speed, fixed gear and track bicycles, and 3/32" is used on derailleur-equipped road bicycles such as racing and touring models.
