-bump- Any ideas on the temporary setup why I'm getting nothing from the motor?

The green light is on on the controller? If it's red, then it has a fault and will not do anything.
Also, make sure the controller is configured properly for your setup, e.g. if you have a 0-5K throttle vs a 5K-0 setup. If it is 5K-0 but your throttle is 0 at idle and the high throttle lockout safety is enabled in the controller configuration, it won't do anything.
Go into the configuration software for your controller and make sure it is set up properly.
I recall having issues getting mine going at first too. Even when I reconfigured, it wouldn't change the parameters until I tried it a few times. It was weird.

That's an awesome looking bike. Reminds me of the movie Charge.

Thanks. I'm still not done with the body. I'm going to make or have custom made some fairings for it.

I'm having some difficulty with the colors on my throttle and the controller. I'm color-defficient, so I need some assistance. I'm using the Magura throttle (0-5k ohms). It has a BLACK, BLUE, and RED (BROWN?) wire. Alltrax says BLACK goes to #2. Got it. #3? I tried both the blue and the brown/red/whatever color on the #3 terminal and loaded the Alltrax controller program and got no response from the throttle.



It would help greatly if I knew which colors went where, and then I can then troubleshoot any software problems with Windows 8.1 and this Alltrax program.

With BLACK + BLUE I get 2 green blinks, which means: 2 Green LED flashes = 5K-0 ohm resisitive

With BLACK and BROWN/RED/WHATEVER I get 2 Green flashes and then 3 red flashes.

I'm not sure but you could test the resistance between each pair of those wires with a multimeter. Change the throttle position, test again.

Looks like all three wires need to be hooked up. I think you're missing the red connection to 5V, blue should go to #3. Basically it's always seeing 0V unless you hook up red to 5V. Do you have a 5V source?

I don't have a 5v power source. I've got a bunch of little 12v batteries and then the 72v battery pack. That's it. Nowhere in my research did I ever see a 5v source required.

The Alltrax doesn't need +5V. Just a variable resistance throttle. 0-5K. Or 5K-0.

I figured as much. I'm going to mess with some of the alltrax settings. But I'd like to know if the wiring is correct. Like I said, knowing the wiring is right would make software troubleshooting easier.

-edit-
I'm gonna mess with the ohm meter and test resistance in a bit. Got tied up with other things.

I programmed the controller, AGAIN, because I thought I already set it up months ago. And i found the proper wires and connected those to the controller. I'm till waiting on the resistors and stuff from China. Been about two weeks now. Still waiting.

I'm hoping to get as much done in the next few weeks because I'll need to pack up stuff and get ready. I'll be away from home for 6 months, so this project may seem dead.
