Abstract

A bicycle gear assembly comprises first and second sets of cog wheels, each having at least three cog wheels of various sizes including a largest cog wheel and a smallest cog wheel. These two sets are oriented so that the largest cog wheel of the first set is aligned with the smallest cog wheel of the second set and vice versa, the first and the second sets of cog wheels define at least a first, second and third pair of substantially aligned cog wheels. Additionally, a chain is mounted about a first pair of the aligned cog wheels and a gear shift assembly is adapted to move the chain from the first pair of substantially aligned cogwheels to the second pair of substantially aligned cogwheels and from the second pair of substantially aligned cogwheels to the third pair of substantially aligned cogwheels.
