The present invention relates to a gear structure of a chainless bicycle. The gear structure of the chainless bicycle according to the present invention, in the gear structure of the bicycle, includes: a rotary disc which has a first through-hole which is formed at a center part and is combined with a rotation axis of a pedal, comprises multiple first mesh holes at an outer side of the first through-hole, and is rotated by external force of a user; a rotary gear which is rotated in a vertical direction as to rotation of the rotary disc by being meshed to one side of the rotary disc; a rotary shaft which has one side connected to the rotary gear, has another side comprising a driven gear, and is rotated by the rotary gear; and the driven part which is rotated by the rotary shaft, is meshed to the driven gear, and is rotated in a vertical direction with respect to rotation of the driven gear. The objective of the present invention is to provide the gear structure of the chainless bicycle which enables the user to use the bicycle more conveniently by solving inconvenience of a bicycle adopting a chain-gear method.
