ABSTRACT:
A bicycle with a triangulated crank structure replaces the single span crank arm which connects the spindle to the foot pedal on bicycles today. The triangulated crank structure is typically comprised of several sections including two linear spans of structural material arranged so that one end of each linear span connects with the other to form the vertex of an acute angle, proximate to a pedal attachment area. From the vertex, the linear spans diverge and each connects at its opposite end to separate locations on a structural element attached to an end of the bicycle's crankshaft or spindle.
