The invention discloses an auxiliary power transmission structure of an electric chainless transmission bicycle, and specifically discloses the electric auxiliary power transmission dedicated to a shaft transmission bicycle without a chain transmission, the auxiliary power of the motor unit thereof is not transmitted by other mechanisms (e.g., crank mechanisms, wheel hubs, and the like) of the chainless transmission bicycle, but acts on the transmission shaft without the chain transmission directly or through necessary gear banks, so as to achieve the purpose that the electric auxiliary power of the chainless transmission bicycle is directly transmitted on the transmission shaft at the final stage of the power transmission, thereby reducing the loss of the auxiliary power transmission, and further achieving the purpose of saving electricity. Moreover, structures of relative mechanisms are simpler and more concentrated; the number of the parts is less, thus effectively reducing the cost and the usage of space.
