Got that all sorted and reinstalled the motor. I also put on some new tires I picked up.
Went for a quick test ride. The new tires are great on the road and the trails. I still had the chain skip feel though. It wasn't as bad, but it was there.
I checked the rear wheel again and replaced the brake pads. While I had the bike apart I decided the check the no load amps to make sure I had the phase wires correct for reversing the motor. There were about 7amps, so I decided to try a couple of other combos. On one of the combos, I heard pop and smelled the magic smoke from the motor. Not very happy with myself. No response from the motor even on the combo that originally worked.
So out comes the motor again and this time it comes apart. Good news is that the gears in the motor all still look new. Bad news is that after opening the motor, it is obvious I blew a trace on the circuit board.
I figure I can solder in a bit of wire to repair the blown trace. Then I should be up and running again. I have narrowed down the chain skip feeling to the chain on the first stage skipping. I'm not sure how it is happening as there is a tensioner on it. I have to figure out how to keep that from skipping.

lol, good job dude!
It was nice to see how the bike changed from beginning to end.
How do you like the hard tail? I want to make a non-hub electric bike also and being that I live in NJ the roads may be as bad as the dirt trails you were riding one
Thanks man! great bike... Hope mine turns out as successful as yours is

It might be an alignment issue and something might be twisting slightly. I'll check the rear sprockets and the bike chain as well. It could be coming from the rear wheel and shaking the entire drive train.
I set up the first stage tensioner so it could not move, but the skip was still there. In doing so, I destroyed the wheel I had in the tensioner. I'll have to find something else to replace it with. It was just something I had lying around.
I'm so close. It is getting frustrating now. I just want to ride.

After all that I could have changed them easily. I was sure from the sound that the skip was coming from the first stage, but I think it was just the shock of the skip at the rear creating an audio illusion.
I am off the get some new sprockets and see if that sorts it. Fingers crossed. Maybe I'll go with some new ones this time.
