The intermittent problem has not returned since the last work done, so hopefully it fixed it. I rode 14.74 miles today on a trip to a picnic, including some very rough sections of road, and had no cutouts, and had none on the last work trips either. Hopefully it was something I fixed permanently rather than something just hidden for a while.
After the trip I went to Goodwill's half-off sale at a couple of their stores, only finding something useful at one of them:
One of these will replace that drinking-cup arrangement I have the CFL headlight in right now. Since I have no lens for it anyway, it won't really affect the light distribution, I think, and it will look a LOT better:
Data from the trip is for a route:
1) from my house to the entrance to the center path of Arizona canal at 29th Ave just north of Dunlap; this is all by motor at usual speeds of 19-20MPH, and 5 complete stops/starts. I think this is about a mile.
2) On the canal until it crosses 12th street near Glendale Ave; this is all at 13-15MPH, while constantly pedalling very lightly (so I don't upset anyone on the path by being a "motorcycle" since it already looks so much like one to some people). There were 6 complete stops/starts that I recall, maybe 7, having to cross various streets. This was about 6 miles. Also, I didn't intend to go that far, was only supposed to go about 2 miles, and turn south at 15th Ave, but I screwed up daydreaming and didn't notice where I was until the canal began going southward and I started trying to figure out why and where I was.
3) At 12th street, I continued south to Rose Ln and then east to Central, South to Bethany Home Rd and then south on 15th Ave to Encanto Park where the picnic was being held. That's about 4 miles back to 15th Ave, and about 5 more miles south to the park. This was all motor, no pedalling, and at anything from 15MPH for the Rose Ln part (lots of kids playing and other slow traffic), to 17-18MPH for the rest of the way (trying to save a bit of power so I could still get home later, but that turned out irrelevant).
(all these are very round mileage numbers and actually don't add up right for the actual mileage).
Total Wh/mile ended up as 16.5, whcih is very low for CB2; typically it's about 23-27Wh/mile for my work commutes, up to 30wh/mi for ones where it's heavily loaded or there's a lot of headwinds.
20.0 mph max
13.7 mph avg (Seems really low for an average of the above)
1h 4m 27s trip time
I'm quite surprised that I only used 5Ah, because with all the faster riding in there of about half the trip (say 7 miles), and all but maybe 6 miles of the trip (say 9 miles) being motor-only, I'd expected to be way past half-used on the 13Ah NiMH pack. Although of course I don't expect I'd actually get 13Ah out of the pack anymore, even if I only get 10 that's still only half used.
As said before, once I had wasted power correcting my daydream overshoot of several miles, I rode slower to use a few less watts against air resistance, especially since it seemed to be fairly windy (against me both east and south, of course, the majority of the trip distance).
I didn't end up having to worry about it, though, because a couple of friends at the picnic had some stuff to bring me and had brought their truck to carry it and also CB2 back to my house. Partly since I wasnt' totally certain I'd have enough power to get back home without haivng to really pedal hard enough to hurt my knees, I decided to take them up on it.
This is some of the stuff, including an abandoned project one of their friends gave them, whcih I might just keep as-is and try to finish (though I'd put functioning pedals on it somehow so that it would be legal to ride here; without them it's not).
The Trek frame is similar to the one I have that's intended for my cargo bike, but not identical. Is probably older, given the seatstay attachment style:
This is probably the shock fork off of that FS frame I noted previously:
It's not a great fork, or much suspension, but I guess it's better than none. The dropout ends are actually separate, and appear to be pressed into the bottom of the shock tube, not bonded into it or welded or bolted in place.
So no hubmotor on these. Plus they're alloy of some sort.
The scooter wheels are tubeless but not airless, maybe 8" diameter I think. The original small-chain sprocket has a regular bike sprocket bolted to it; presumably he'd planned to use that to drive it from whatever motor he'd planned to mount on it (don't know what that might've been). It also has a drum brake that appears to have a rubbing problem inside. I'd expected a band brake, but it seems to be drum.
They also donated a couple of different kinds of 3/4" video tape to my media collection (I collect various kinds of information storage media, anything from core memory to punch cards to magnetic tape, optical media, solid-state memory devices, etc., although I'm not sure why I started I still keep it up).
Then there is a box of assorted stuff, a few celphone chargers/etc., and some bike parts:
There are some Biopace rings (28-38-48) and the spider/crank for them (though not all of the bolts for the set), part of an ISIS type crankset with just one ring (I think the other ring is the one on the scooter wheel but I'm not sure; they're both 4-bolt types), a couple of freewheel cassettes (one missing most of the bearings inside from the sound of it, and the other just about exactly like the 7-speed Chinese cassettes I see advertised on various rear ebike hub kits.), a couple of Shimano trigger shifters that are separate (not part of brakes), perhaps early models?, most of some rear derailers and all of some front ones, assorted screws, etc. And a front hub with no axle or bearings or cones (these parts probably being what was used as the footpegs on the scooter-to-be).
These are the Biopace rings directly from above, next to a granny ring from something else:
One thing I really really didn't expect to come home to, though, was that now I need a new back bedroom door:
Nana decided she didn't like being cooped up in there while I was gone for some reason, though she hasn't had a problem with it before.
It's patched with 3/4" thick plywood right now (she should have a hard time digging thru that if she should try again), but I still have to replace the door at some point. (I don't think I can repair it in a way that will look like it is original, with anythign I have around here at the moment).
