The present invention relates to an accelerating power conversion device for a bicycle. The accelerating power conversion device for a bicycle includes: a bottom bracket unit having a hub at a predetermined diameter in order for a pedal shaft to be installed in the lower part of a bicycle frame to rotate; a rotating driving unit in which a ring gear is integrally fixed to the pedal shaft passing through the hub; a rotating accelerating unit having a carrier fixed to the inner side of the hub to face the ring gear, multiple planet gears formed in a pair in the carrier; and multiple solar gears installed to rotate; and a driving sprocket rotated by the rotating accelerating unit. Therefore, the accelerating power conversion device for a bicycle drives the bicycle forward regardless of normal rotation or reverse rotation of a bicycle pedal. The driving sprocket rotates at a rotation speed higher than the rotation speed of the bicycle pedal and enables the bicycle to drive at the high speed by acceleration of the driving sprocket. |
