This is a new, best effort. And I've done this one

Removing the rear wheel for tire repair

The good news is I eliminated removing the motor from its mount, less chance to loose stuff. The bad news is now there are 19 steps instead of 13. But I know these work, at least did once. I guess the others did too, but I think these are better. I now think I could manage it by the roadside.

Removing the rear wheel for tire repair

1) Loosen brakes, Normally removing ‘noodle’ (elbow shaped metal tube at brake arm on motor side) from mount will do, or loosen brake cable
2) Cut wire tie on motor lead closest to motor, need a good knife or diagonal cutters
3) Fasten motor to battery rack using wire looped around top standoff,carry some maleable wire
4) Loosen both 15 mm axle nuts
5) Loosen 17 mm thin nut between dropout and motor mount (Requires thin (cone) wrench)(A cone wrench is a bike store item)
6) Remove 5 mm bolt clamping motor mount to dropout
7) On the adjusting stud (points to front at front of motor mount) back off the 5mm nut furthest right
8) Slide motor mount forward, to loosen chain
9) Remove chain from motor sprocket
10) Swing front of motor mount down to free adjusting stud on front of motor mount
11) Lower wheel, mount and motor a bit to expose 17mm nut
12) Remove 17mm nut (that holds mount to axle) from axle
13) Remove mount with motor from axle, wire will hold it in place. No tension on motor lead
14) Loosen 15 mm axle on right side more
15) Swing derailleur down out of the way to free pedal chain from freewheel
16) Remove wheel
17) Fix tire
18) Install by reversing steps 16 to 1, including replacing wire tie
19) Adjust motor mount front to back, using the nuts on the adjusting stud so that there is 3/16” movement when the chain is pushed in the middle of its span

I should add a couple of us are working on a mod to make tire changing easier. It involves a master link in the 1/8 drive chain: motor to freewheel and a slotting out of the mount plate and possibly a bolt on reinforcing plate over the new slot. That means the mounting plate and motor would stay in place and the axle would come down thru the new mount plate dropout.

Also, in case anyone is curious, I'm working on a writing project (for 'work') at home today. When I get bored or blocked I come over here for a while. Seems to work for the project.
