Abstract

The present invention provides an improved bicycle crank and chain wheel assembly. The assembly includes a ring shaped chain wheel arranged to rotate about a first axis of rotation and a slotted guide is also provided that extends outwardly from the chain wheel. The assembly further includes a pair of opposed cranks arranged to rotate about an axle having a second axis of rotation. A projection extends from one of the opposed cranks to move along the slotted guide. The slotted guide is disposed to constrain the projection to move linearly along a third axis as the chain wheel revolves, the third axis being non-coincident with the center of a downward power stroke of the one of the opposed cranks in order to optimize transfer of power from the crank to the chain wheel.
