From your description, it definitely sounds as if the wiring, plug or switch on your left hand brake lever is faulty.
If you had swapped the brake connectors over and the opposite lever then activated the regen, it would have been due to a fault inside the front harness multi-connector instead.

I'm now puzzled as to why you say it's your rear brake that's too powerful, as in my experience, most rear brakes are typically connected to the left hand lever, but perhaps yours is different?

As your left lever is faulty (assuming it's the one connected to your rear brake) you should only experience the strong regenerative braking force when the front brake is applied, and not when the rear brake is applied on its own.

As I recall the left hand brake lever controls the rear brakes and the front is controlled by the right brake lever.  I have another folding bike that has rear coaster brakes and the left hand lever brake is connected to the front brake.  So I am not certain what the correct setup would be for lever braking systems.
I guess what your telling there are three maybe four possible problems...
1 the lever
2 brake cable
3 connecting ports
*4 motor controller (still a possibility?)

How do I test each, cable seems obvious, but the 2 or 3 other possibilities I would like to know any testing procedures.  Or is it just best to drive over the Gary's house :)
Thanks Alan

I can't say about any others but on the Smart Pie both brake switches work only one wire to the controller, activating either does the same thing, it cuts the throttle and starts the regen braking at whatever level the motor is programmed to. I've traced all the wires myself, I'll copy it onto a spread sheet & post it one day as I had to trace every wire because I didn't use the standard wiring loom.

I can confirm this. All on all kits the brake lever simply closes a switch that kills the motor and activates regen (if regen is enabled). Two levers are simply wired into the same circuit.

Since it seemed odd that the motor cutoff is only working with 1 brake lever, I did another test. I took cable 1 and plugged to slot 4 and cable 4 into slot 1, then back to 1-1 and 4-4, only the right lever brake cuts off the motor.  Am I right to assume the left cable on the lever is faulty or the port that plugs into it?

I'm assuming from this test both levers are mounted on the bike. If the left lever is unplugged and the right lever in 1 or 4 it cuts the motor it is working fine and the 8 pin wire harness and controller are fine. Then the opposite setup of right lever unplugged and the left plugged into either 1 or 4 and does not cut the motor then the lever is faulty or the pins in the plug are bent.

Please don't do that, my home is for my family, not for my business. No one in my family is interested in people dropping by from the internet.

Thanks OZ.  Man, that seems like a huge waste of money to change the value of the regen brake setting,  >:(  and I'm not even sure if that's the problem.  Also the other problem I see is I am a Mac user, and it looks as if this only works for windoze computers.  Anyone around TO  beaches want to plug their computer to my hub :)  So Oz your certain that what I am going through is the regen braking system?  Thanks

You could just come to the next Meetup. If you let me know your coming I will bring my laptop and stab your pie with my USB cable. When can do several tests and I'm sure you can find a setting that is appropriate. I can bring a spare brake lever to and we can resolve that as well.

Sorry for the tardy response, I Just got home, rode over a nail and had to walk my bicycle home the last 6km, then repair the tube  :-[  As for the kill switch not working.  It could be the lever or cable.  I unthreaded the cable cap  but unable to remove the cable from the lever to swap.  Now, for the next meet up, it depends on the location I will try and make it and inform you.  I'll post something if there is a update with the lever cable I am trying to remove
edit:
Just checked the pins.  Both pins are fine.   Now it's either the cable (continuity) or lever.

The cable is soldered to the switch.
Yes you have to unthreaded the cable clamp.
And push the wire through the lever.
Now you will be able to remove switch cover.

There is no need to take anything apart. If I am correct at reading how you tested it and there are no bent pins then it is the lever that is defective.

Do I need to create a ticket, or do I need to do more testing?

As for the bill of Sale I assume the email from GM confirming my purchase would suffice as a receipt?
BTW it's only the one broken lever brake and cable is to be shipped not the entire unit?

Don't worry about any bill of sale. I'm not asking you to send me anything. Just create the support ticket and I'll send you a new brake lever. Anyway lets kindly take this to the ticket please.

Thanks GM and GS for the lever.  The lever now cuts off the power, but it seems it's for the right handle, who cares it works.  As a interesting note on my field test my bike hit a small bump and the motor cut out.  I noticed the LED on the throttle was not lit.  So I re-seated the power connectors but it still not working,  checked voltage on battery with meter, measured 36V.  My only suspicion was the new lever installed.  Re-seated and the throttle light up again.  Test ride went fine.  Not sure what triggered the power failer.  Any ideas?
