So, if you got the reduction down even further, you would get much better efficiency. Or you could run a larger motor with lower KV. You had just been running that motor way beyond its efficiency range before.
Anyway, it is looking very nice, ineed!
Yes, the gearing is still way too high, i went for a 36v ride tonight ( led light attached to my helmet, pitch dark out there at 6pm !! ) used up 5ah from my 40ah pack and even at 36v i can't use the whole range available by the Nuvinci.. battery attached to the bike and not on my back makes for a much more comfortable ride !!!!
I have the 200amp shunt installed, CA calibrated for it ( Thanks Oatnet !! ) .
Need to spring load the tensioner on 2nd stage #25 chain.. that's this weekend's project.
At 48v on a stiff voltage lipo pack i will need to get the gearing way way way down, this thing is going to be a rocket once i get it all sorted proper......
Next step, 60t to replace the 45t on the 2nd stage.
