The invention discloses a variable-speed transmission device of a tricycle. The device comprises an inner variable-speed hub, a flywheel assembly and a variable-speed driving base; the inner variable-speed hub is further provided with a middle shaft, a variable-speed gear assembly is arranged in the inner variable-speed hub, the variable-speed gear assembly is in transmission connection with the middle shaft, and the variable-speed gear assembly can drive the inner variable-speed hub to rotate on the middle shaft; the flywheel assembly is arranged on the middle shaft in a sleeving manner, is in transmission connection with the variable-speed gear assembly and can drive the variable-speed gear assembly to work when rotating; and the variable-speed driving base is arranged on the middle shaft in a sleeving mode and is in transmission connection with the variable-speed gear assembly, and gear shifting of the variable-speed gear assembly can be driven. Compared with the prior art, the structure of the tricycle is changed into the gear inner variable-speed hub which is durable and hardly needs to be maintained, and a variable-speed gear is contained in the inner variable-speed hub, so that the appearance of the tricycle is more attractive, and meanwhile, the trouble of rainwater and mud is resisted.
