Here is a video of a quick walk-around:

AlanB, thanks for the kind words, detail and background info.
Veloman, you are correct, one does need a long power lead, which is why I used 4ga wire for that run. One can minimize the need for extra slack by crossing the wires under the steerer tube, instead of running them straight down the side of the frame. This way, when you turn the wheel, the wire length stays the same. If you read back in the thread, others have tried a variety of handlebar mounts with success, although I prefer the hard-mount myself. Here is what that cross looks like:
Wildhare, you were absolutely correct about the freewheel - here is a picture of the brass 1/2" x 3/32" and chrome 1/2" x 1/8" - the skinnier teeth fit through the chain. Thanks!

Also, some more pics of the phase/hall bundle coming out of the dremeled dropouts/plastic cup.
Took it out for some test runs today, got 43mph on the flats in a tuck, 41mph when I stand up. After I got home, I lifted the rear wheel to get a no-load speed of 53.5mph at 79.3v .
I am calling the x5403 a 9.65kv motor. Per my calculator, a 9.65kv motor at 79.3v in a 23.5" wheel will give the 53.47mph unloaded, and an the 80% estimated loaded speed is 42.78mph, right what I saw today. That would give me 86mph if I went to 144v, a little short of the 100mph I would like to reach on this mule. I was hoping for more of an 11.5kv, which would give me 52mph at 72v nominal, and 104mph at 144v, but it is an entertaining ride nonetheless.
I am having problems entering an rshunt value on my CA V3, so I can't calculate WHM etc, but acceleration is brisk to say the least. The V3 tamed down the twitchy throttle, and I set the 3-speed switch 30% 50% 100% so I can launch on 30% to keep it controlled on launch, and quickly switch to 100% for hard accelleration. I am really impressed with the CA V3 and its throttle control capabilities, not to mention the ability to toggle between three presets (Emoto, eMoped, ebike) on the fly. I cruised up steep long hills at 36mph, and the motor/controller were barely warm.
The bike weights 118.6lbs. Sounds like a lot, but consider that it is built with moto rims, tires and the v12 of hubmotors. Here is a breakdown of weight:
40.50 rear wheel
11.40 front wheel
28.50 Battery Pack
36.30 lbs frame/forks/controller/everything else
