<p>The present invention relates to an automatic output apparatus for converting two way drive into one way and a bicycle fabricated therewith, in particular to an automatic output apparatus for converting two way drive into one way drive, in which planetary gear group and one way bearing are engaged with each other so that driving power produced by driving in a forward or reverse direction without any separate outside operating device or action regardless of the driving way of the user can be smoothly converted into one way output, planetary rotation state, and backward breaking state, and a bicycle which is fabricated by such an one way output apparatus and removing means so that locked backward breaking state can be forcibly disentangled when backward progress is required.</p> |
