Hi I would like some help and advise on a replacement controller for my bike, I have carried out some basic checks to the handle bar on/off speed control and suspect that this item or the main controller in the bottom bracket to be the problem , I checked the battery voltage this is at 28 volts and it runs another bike quite well enough. A few months ago I came back from a ride plugged in to charge and noticed the next time that I had not got power to the speed control no l.e.d. lights were on. I have been looking for replacements for the two items mentioned and have found that they have more wires than my present controller which is a KZQW22a LBH 24 volts this controller has the 3 large wires going to the hub motor but not the five motor hall sensors and only 3 wires to the hall sensor on the bottom bracket, the brakes wires are only two but I suspect that these are connected together in parallel along the route to the controller. The wires that are on my controller are as follows. speed cont. 5 off red, grey, orange, yel, black, blue, throttle 3 off red, yel, blue, hall sensor on bottom bracket 3 off brown, blue, black, brakes 2off white, black, motor 3 off larger wires yel, green, blue, bat. 2 off red, black, I hope that I have given you enough info. for my problem if you are able to help in some way I would be grateful also could you help on the best place that I could purchase these items ? many thanks Patrick Checkley (my email add. is checkley.patrick @gmail .com if you should need it) once again many thanks
