Been riding DGA to work/etc since the above, with no problems so far, though I don't like the feel of the "airless" rear tire. Not sure if it's just the squishierness of it, or the vibration from the MTB knobbies, too. I'll get used to it eventually; I think for safety's sake of having a working backup everytime I want to ride it, or need it, I'll just leave that one on there.
Today I picked up a complete trailer full, stuffed to the top, of dog food donations, various brands and stuff, some open and partly used, some just open (doesn't look like any was used), but all of which will help feed these fuzzy monsters.

But in the process I thought I had destroyed the Fusin gearmotor hub.
Fortunately it revived after cooling down, with some ice packs and icewater I carry with me (for me, but in a pinch....)
so it's probably at the limit of what the hall sensors could take, perhaps; or else the controller was a part of the problem. It was so hot on the outer casing that I couldn't have kept the back of my hand on it for long, when it first cut out.
I thought it might be a connection at first, so stopped, got off the bike, and started checking wires, and when I touched the fork leg the controller is bolted to, it was awfully warm, and I brushed the motor with the back of a finger while finding the cables and that told me exactly what the problem was.
The controller was hot, too, but no more so than it often gets in this heat, whcih was still over 95F, after dark sometime, and very humid (helpful for coolign the motor/controller but not me). I'm just REALLY glad it was nighttime, and not midday.
After cooling it down to a bearable temperature, probably no more than 120-130F on the outside, and not appearing to get warmer while I waited, so probably at equilibrium finally, it worked. I still didn't trust that I wouldn't burn it out, though, so I decided I'd try riding home pedal only, but I coudln't do it, not with the load.
So I had to walk the bike and trailer full of food home the last mile and a half, limping on my not-yet-healed right ankle and my no-longer-getting-better left knee. That took a while; I'm guessing around an hour, with all the stops for rest and water. I felt the motor at each stop, but it never seemed warmer, or cooler, just about the same.
I couldn't ride without the motor, because pedalling even in the very lowest gear would still cause side-to-side sway of the whole bike/trailer setup, as I couldn't get going without cranking down really hard, standing on the pedals, and that immediately started the sway that I couldn't balance the bike with.
I did finally for this ride have the turnigy meter on the bike, but somewhere in shuffling stuff around in the cargo pod, probably when cooling off the motor, I lost the paper I'd written the journey so far down on. So all I have is the data for the mile or so from the last pickup point to the overheating cutout point, plus an hour or so's walking with the headlight and bike/trailer taillights on, which take about 75W or so, IIRC.
I can't remember what the Wh or Ah reading was at the cutout point; I just remember the voltage was still 48.something volts, with just the lights as load, because I checked that first in case I'd hit LVC.
I don't have actual trip distance because I haven't yet remembered to load the Veloace on the PDA Bigmoose sent me, and it always gets lost after the battery runs down on my other PDA, which I keep forgetting to charge after riding.
As soon as I got home, I stuck the front yard garden hose into the spokes to hold it and turned it on a bit, to flow cool water over the hub to get the temperature down faster internally, though any damage it has is probably already done.
Then after feeding the dogs, I spent the last hour or so securing the dog food into various bug-resistant containers, and storing it in places the dogs generally cant' get into.
Then they got to lick all the bags, and do their shredding thing with them that they so enjoy (Bonnie likes to do it from the inside of the bag, walking right into the big bags and just tearing it to bits from inside out).
