Claim:
1. A transmission of e-bike motor, the transmission of e-bike motor comprising: a first planetary gear system; a second planetary gear system; and a connection member interposed between the first planetary gear system and the second planetary gear system to transmit or block a turning effect in response to a rotation direction, wherein the second planetary gear system comprises: a first carrier having a shaft insertion hole formed to be coupled with a shaft; a planetary gear coupled to the first carrier; a fixing pin coupled to the first carrier for rotatably supporting the planetary gear; and a bearing disposed between the fixing pin and the planetary gear for rotatably supporting the planetary gear; wherein a rotation of the first planetary gear system is transmitted to the second planetary gear system by the connection member, in case the first planetary gear system rotates in one direction, and wherein a rotation of the first planetary gear system is blocked to the second planetary gear system by the connection member, in case the first planetary gear system rotates in another direction.
