LM317T Voltage Regulator with Pass Transistor

the v.2 controller will do 60v with a resister in line with the voltage regulator.

I added a pot of unknown wattage (guessing 1W) in series with the resistor leading to the voltage regulator. A 12V zener diode is more typically used, but ~200Ω in addition to the existing power resistor seems to work equally well. The freewheel isn't really that loud. It's just the camera trying to equalize the sound levels, I guess. And, no, my rim isn't out of true. I just didn't put the tire on very well, LOL. Here's a link to everything that's gone on with this bike. It's pretty long, though, and the first hub on this bike was a WE BD-36, so info on this iteration doesn't show up for a few pages. endless-sphere.com
