Abstract

An apparatus for increasing a driving force of a bicycle by use of a crank shaft that can convert ascent/descent linear motion into rotary motion is disclosed. The apparatus includes a crank shaft structure installed to a bicycle, an extended crank shaft extended from a crank shaft and linearly moved up and down to rotate a rotor of the crank shaft, a pedal support of a rotor inserted in a space, which is formed on a front portion of the extended crank shaft, for driving the rotor, and rotary geared wheels installed to shafts of the rotor and rear wheel.
