My first test rides with a GSM crank motor and have found it very different to my usual hub driven bikes to use.
Me and the motor did not get on with changing gears with the motor under load which it generally always was, I could not get to blip the brakes and change gear in time so always ended up with a clunk.
Since I'm using a KT controller I cannot just plug in a BBS gear sensor.
But I come up with a solution using a BBS gear sensor and I don't want to cut the cable on the expensive gear sensor either.
So cut the socket off a cheaper BBS brake wire 'Y' adaptor and solder on an old HWBS wire 3 core cable with a jst plug on the end,
Connection is red to red, black to black, then the other colour is signal to signal.
Connecting this to the KT controller brake sensor circuit really has transformed the bike for me and has been a well worthy project.
Obviously when going really slow under load you still get the clunk because the grears haven't had time to change before the power returns.
