Ok, if I understand you correctly: the coupler is welded to the motor shaft? I'm guessing it's more likely you have a keyway and setscrews. Sorry to be so picky, but my setup is using a hub as well, but without any welds, just setscrews, and I don't think it will stand the test of time. Since your system has given you a proven 62 kilometers, I'd like to emulate it as best I can...

I dont have a pic to post at the moment so i will explain as clearly as I can.
The motor has a 7/8 keyed shaft. The transmission input shaft is as origional.
The motor and transmission shafts face eachother end to end with a 1/8" gap between the shaft. The hub slides over the motor shaft with a key and setscrew the trans uses the clutch hub the two hubs are welded together. Will see if i can get a pic up soon.

First two usefull trips in the electricfly happened this week. Grocery shopping on sunday and school supplies shopping for the kids today. Both trips approx 10 km round trips on a 60 km/h city street. They were on a fairly major route in winnipeg and there were no upset drivers behind me. No spectacular acceleration but enough to prevent a traffic hold up. Im sure I would love an upgrade to 48V or 72V but I must say I am pleasantly supprised with the functionality of the car thus far. Battery voltage after trip (with a rest period for accurate reading) was 6.1V per cell avg. over the pack.

Do remember that I am keeping speeds to a sedate 45-50km/h most of the time. There are no large hills around here and the most I have to tackle is one bridge on the way to work. Havent tried that one yet. Just taking baby steps with the electricfly till I get to know it a little better.

I plan on 48v. I will use a 72v controller though, so that, if I choose, I could up the voltage. If I get anywhere near your results though, I'm sticking with 36v!! All I need is 25 MPH and 1.4 miles of range....
