PURPOSE: A variable power pedal using the eccentric rotation of a bicycle driving gear is provided to enable a user to easily ride a bicycle with low power since the radius of rotation of a pedal is expanded in a driving section and is reduced in an idle section. CONSTITUTION: A variable power pedal using the eccentric rotation of a bicycle driving gear comprises a driving frame(1), an eccentric arm, and a gear(3). The driving frame is installed on left and right sides of a pedal rod(6) in order to fix an eccentric arm formed with an eccentric shaft. The eccentric arm welds and fixes the pedal road shaft. The gear converts free rotation of left and right pedal rods into simultaneous rotation. |
