Hi community this is my first post on here and am passionate about the whole electric bike builds and am an electrical engineer and have a high mechanical aptitude so hopefully I can be an asset. I am currently in possession of an Aprilia Enjoy Racing - I had been searching around for quite a while looking for something stealth but had the build quality and engineering to handle 5-10kw and still not look too red hot for the boys in blue. This is my thoughts on the project thus far; I have read good things about Crystalyte and chosen to go with them unless I'm reasomly advised a viable alternative. I was thinking of front and rear both Crystalyte however I would like a 80 crown on the rear and in the future a front hub but ATM just rear wheel drive. I have a dead weight original controller but great g/box and motor on it now. I'm building a custom 16s2p 20AH 48v system using 10ah cells. I would like to know where I could find the best deal in Australia for a Crown 80 and a 48v 50A controller ( Crystalyne ) I have found deals on eBay from hi powered but also read in a forum post about an Aussie on here who had some great custom Crystalyte gear if anyone may know his alis that would be great. So considering the build dream what are the community's input - I have been reading about oil cooling some of the earlier hubs 3 series but I Dont think a crown would need it due to its wider stator as I'm concerned about saturation and demagnification of the magnets so i think a decent pc programmable controller is a definate. I am also interested in a decent BMS Any inpup will be warmly received - Thanks in advance Deeze.
