PURPOSE: A bicycle having acceleration pedals using a rewinding function is provided to minimize power loss by elevating pedals using the reverse rotation of a rotary shaft and moving the pedals frontwards using a reverse gear. CONSTITUTION: A bicycle having acceleration pedals using a rewinding function comprises a frame (100), a longitudinal-axis crank shaft (200), an amplifying unit (300), an elevating unit (400), and a rewinding conversion unit (500). A rear wheel (110), a saddle, and a handle in which a front wheel (120) is fixed are installed in the frame. The power point (260) of the longitudinal-axis crank shaft is fixed to the frame, and the longitudinal-axis crank shaft generates power when a passenger steps on the pedals. The amplifying unit is connected to a pulley (310) formed on the end of the longitudinal-axis crank shaft and amplifies the generated power. The elevating unit moves the bicycle by rotating a rotary shaft (410) connected to the rear wheel frontwards. The rewinding conversion unit moves the bicycle frontwards by elevating the pedals and converting the reverse rotation of the rotary shaft into the forward rotation. |
