The invention belongs to the technical field of electric bicycles and discloses an electric bicycle transmission device and an electric bicycle. The transmission device comprises a power piece, a first bevel gear, a second bevel gear, a flywheel and a bearing shaft. The first bevel gear is connected to one side of the power piece, and the second bevel gear is arranged on the surface, away from the power piece, of the first bevel gear; teeth of the second bevel gear and teeth of the first bevel gear are the same in rotation direction, the flywheel is arranged on the peripheries of the first bevel gear and the second bevel gear in a sleeving mode, and the flywheel has a first state in internal meshing transmission with the first bevel gear and a second state in internal meshing transmission with the second bevel gear; and the power piece, the first bevel gear and the second bevel gear are sequentially arranged on the bearing shaft, the power piece is rotatably connected with the bearing shaft, and the second bevel gear is fixedly connected with the bearing shaft. According to the electric bicycle, the transmission device is adopted, when the power piece is started to run, the flywheel is separated from the first bevel gear and slides to the periphery of the second bevel gear, and the power piece is ensured not to be stuck.
