Those tires look like you've been power drifting.
It still looks great. I'm sure you'll get it all done up right soon.
Thanks!
"power drifting" probably describes the turns pretty well--as mentioned previously, there's scrubbing in the turns as the aback end drags/slides around the turns unless I slow way down (better than tipping over!). Slowing down could be hazardous with some traffic behind me, because I'd have to slow down to like 5MPH, maybe 8, to keep that from happening on some corners becuase of the condition of the asphalt lets it slide easier sometimes, but it sands away at the tires when it does that.
The hazards are because of the really slow speed, and the impatience of drivers. Why they don't act this way whne I ride CrazyBike2 I dunno, but CB2 can also turn at 17-18MPH without having to lean quite far enough to drag the cargo pods into the asphalt too often. (could do it at full speed without them, most likely). But on this thing, I might as well be on a regular bicycle pedalling around, for the "respect" it gets. :/
Surprising since it's larger than CB2 by a lot, viewed from the rear...but SBC doesn't look like anything they've seen before, while CB2 resembles a motorcycle with saddlebag/boxes (common around here).

Wow that tire ware is crazy. Not sure how many miles you have on those rear tires but that is going to be an issue. This might be a dumb idea but I wonder about hacking on some golf cart wheels. Not sure how a golf cart is actually made in regards to rear axle etc but do you think some old parts off of an old golf cart would be worth concidering. I would think the tires would last a long time, the center of gravity could be made lower etc. It would mean of course if you go with dual motors again you are talking mid drive but you will have the nice torque off the line. I would think you could cushion the ride some what with the low tire pressures you could run on such a hack.
Looking good AW, all the best.
Thanks!
If I were to use different wheels/tires, I'd actually just want to go with moped/MC ones; I'm sure they'd be up to the task well enough, and they'd still work with hubmotors.
If I had any access to golfcart stuff to play wiht, I could experiment with shortening the axles on a differential/transaxle from one, so they'd fit in the space I have on this trike (keep it fitting thru a front doorway). Not sure if the wheels would fit in my fender frames, so might have to cut those off and redo them for that. But presently I don't have any GC stuff, and in all the looking around I've done over the last few years havent' foudn any I could get cheap enough. (wanted to use this kind of thing to add power assist to a wide trailer)
Ideally I'd like to use a middrive to drive both rear wheels, but I've never found a really realy cheap or free transaxle that would do it except for the one on the melted powerchair remains I kept after the fire. I have that taken off the powerchair, and started to take it's non-working motor off of it but never got very far (stuff was stuck so I keep retreating it with PB blaster and hoping it'll unstick eventually, so I don't have to break anything to get it to where I might be able to use it).
It isn't wide enough, so I'd need to extend the axles out from it to drive the wheels (via chain, most likely), and I'm not sure how best to do that with stuff I've got here. Probably would only extend *one* axle, and uuse the other direct, to reduce work I have to do for it. Then use a powerchair wheel stub bolted to the unmodded axle end to hold sprocket(s) to drive the wheel on that side. Make something similar for the other modded end.
As for the tire wear, I think I put about 15 miles on them, maybe less, before those pics. I forget exactly. No idea how many miles they had before I got them off the BMX bike from goodwill.
Got another set of the same kind on another BMX bike given to me, with almost no wear, but I don't think they'll last any longer than the worn ones did. they're jsut not good tires, really thin.
Not gonna go spend money on bicycle tires for this application; I'd rather buy some Shinko or Pirelli tires.
Catch at the moment is that I only have one rim wide enough to put them on. Ypedal still has some more but shipping is exorbitant so gotta wait and see when the money situation gets better again before I buy them. I already bought spokes (on the way from Grin soon) to lace the x5304 into the rim I have. (the other rim like it is on CB2 with the HSR3548).
Also bought spokes from Grin for putting one of hte 9C types into some 20" rim (whatever I have, all skinny) too, so I can try out dual rear wheel drive instead of front wheel; it ought to have a lot more torque than the single 26" front, even with the controllers I presently have (one 25A and one 33A), and be able to startup from a stop quicker than now (it would be tough to get *slower*
).
Tiny's been sick with a cough (and pukey because of that; she's always a pukey dog but right now she re-eats stuff a dozen times or more before it stays down, over several hours
) so I haven't gotten as much done as I planned, just wanting to stay wherever she is at to keep an eye on her. Right now we're outside in the breezy shade, but it's warm enough now (82-83F?) that she is probably gonna go inside soon.
The wifi is only working to an unsecured one nearby if I move the antenna (and thus the laptop; USB won't go that far) most of the way toward the alley fence near the street side, under the middle-of-the-yard mulberry tree (where the lemon tree used to be). (neighbor's wifi works but the ISP hasn't connected at all today.) So when she goes inside, I'll just come back out and check emails and such when she's napping again.
(I left email and text for the rescue to see about a vet visit for her, earlier this morning, but havne't heard back yet).
Anyway...so I haven't gotten to testing out any of the old motors or retesting/troubleshooting any of the bigger controllers.
