ok if anyone is still reading this and interested even after all my anxious rants!! i now finally got this dang hub adapter to stop slipping. I came to terms that just having it clamped with even 20lbs of force was not enough to keep that dang adapter from slipping. i have an ezqmatic tranny so i assumed because its such a beast that there was just too much power with that baby to keep a just clamped adapter still. what i ended up doing is buying a dremel type tool. the no name version. way cheaper. and got a few bits to go along with it that would tear through metal like buttah. I saw a video a guy had on this forum and he made a key way for the adapter to the hub. AHHHHHHHH finally something that made sense. due to simple physic laws this seemed to be the best idea yet and man was it. took a bit of time to carve into the adapter and the hub but it was all worth the time. I now have a realiable motorized bicycle. Please msg me if you have an adapter that slips and need help modifying your hub and adapter with a key way. I feel like i know that thing inside out since it took me about three days to finish all of it lol. Hazzah!!!!!
