    BPM 36V 500W 26(10)

    I bought am electric bike in pieces. It came with the BPM rear hub motor, and a Yiyun YK31C controller. Is this the right combination? The motor has 3 wires going to it so I assume it is 3 phase, but the controller has ony 2, (Y, Bu). If not what is the proper controller/ Thanks, John
