The invention provides an electric bicycle propulsion system and an electric bicycle. The electric bicycle propulsion system comprises a motor assembly, a transmission assembly and a shell. The motorassembly comprises a motor and a motor shaft, the transmission assembly comprises a transmission shaft, a driven wheel and a transmission chain wheel, the distance between the motor shaft and a bicycle front wheel and the distance between the transmission shaft and the bicycle front wheel are smaller than a distance between a bicycle middle shaft and the bicycle front wheel. The shell is used forbeing detachably fixed to a bicycle frame; the transmission shaft is arranged above the motor shaft in parallel; one end of the transmission shaft is connected with the driven wheel, the other end ofthe transmission shaft is connected with the transmission chain wheel, the driven wheel is meshed with an output wheel at the output end of the motor shaft, and the transmission chain wheel is used for being meshed with a transmission chain of a bicycle to drive the transmission chain to transmit motor power. The propulsion system is detachably installed on the bicycle frame, the structure is compact, and a larger thrust-weight ratio can be provided.

    本发明提供了一种电动自行车推进系统及电动自行车,包括电机组件、传动组件和壳体,所述电机组件包括电机和电机轴,所述传动组件包括传动轴、从动轮和传动链轮,所述电机轴和传动轴到自行车前轮的距离小于自行车中轴到自行车前轮的距离,所述壳体用于可拆卸地固定在自行车车架上;所述传动轴平行设置在所述电机轴上方,所述传动轴的一端与所述从动轮连接,所述传动轴的另一端与所述传动链轮连接,所述从动轮与所述电机轴输出端的输出轮啮合,所述传动链轮用于与自行车的传动链条啮合以带动传动链条传送电机动力。本发明推进系统可拆卸地安装在自行车车架上,结构紧凑,且可以提供更大的推重比。
