The invention discloses a bicycle gear transmission mechanism and application thereof. The transmission mechanism comprises a rear axle flywheel gear set and a change gear set. The rear axle flywheel gear set comprises a rear axle flywheel gear A and a rear axle flywheel gear B which are coaxial, and the size of the rear axle flywheel gear A is larger than that of the rear axle flywheel gear B; the change gear set comprises a change gear A and a change gear B which are coaxial, the size of the change gear A is smaller than that of the change gear B, a movable connecting kit is arranged between the change gear A and the change gear B, the movable connecting kit comprises a male part and a female part, and certain fixing force exists between the male part and the female part when the male part and the female part are located at the connecting position; and the rear axle flywheel gear A is meshed with the change gear A, and the rear axle flywheel gear B is meshed with the change gear B. The bicycle gear transmission mechanism is reasonable in structural design, automatic switching of two energy transmission paths can be achieved, and good consideration of high durability, low cost, high transmission efficiency and high speed is achieved.
