I went ahead and bought the controller, display, and PAS sensor from GBK. My biggest problem was dimensions. the 36/48v controller wouldnt fit in the frame so im trying to stretch a 24/36v 250W controller...
Learned a lot recently about Ebikes after buying a non-working one. I think the aftermarket controller currently in it is bad (Brainpower 800a-6) because the wheel won't spin unless I hold the "C" button on the display (LOL). Looking at switching to a KT controller. Currently looking at KT36 17A...
Sorry for reviving an old thread but Im about to give up on my Brainpower controller as I can only get the wheel to spin when I hold the "C" button the screen lol. Where is the best place to buy a KT kit from, im worried ebay or others might be knockoffs.
