I can't wait to get my hands on the kit and try it out. Mike (LightningRods) has come up with upgrades for each part of the GNG kit, one by one. So far, each upgrade wasn't just better than the GNG part, it was great...with nothing left to improve.
I would enjoy trying out a plug-and-play torque-mode throttle + controller, there was a lot of discussion about those a year ago, and some work is being done on that (I don't understand it, but people I respect on electronics like it, so I want to try it when they are available). I am guessing Mike really has his hands full right now, and I have to take my hat off to him for fronting the cash to get 100 of these motors direct from the factory. I would wait at least six months before expecting something like that.
I was impressed with the performance that Christerljung was getting at 100V, but I can't imagine fitting 24S on my frame (I agree that 100V would be lossy, no matter how much fun it might be), the reports that really got me excited was Skyungjae. I have known him long enough that I trust his opinion on an off-road mid-drive. If a better motor shows up, I am certain Mike will try it out and make plates for it, but right now...I am just chomping at the bit to get this one on my bike!
