Hi all,
I bought a BBBS02 to install on my old Trek VRX 400 after reading about them here. I previously had a 9C hub and Lyen controller on it, but the 9C seized due to water ingress. The 9C wasn't suited for crawling up steep hills anyway, which is what I hope to do now.
Parts arrived yesterday so I jumped right in and got the motor fitted. This involved slight frame surgery.
I have one question about the kit wiring, which didn't come with a diagram and I can't find info online. The battery cable and connection up to the handlebar controls/display is self explanatory. I have the speed sensor connected. But there are two "extra" wires coming from the motor - one with a yellow quick connector and one with two small faston type connectors. I can't think what these would be for, or if they are needed?
