Longer test of the new controller today; whcih worked just fine, as did the motor. I definitely like this setup, other than the display.
Display unit actually displayed a speed reading several times during the 8-mile ride, but it didnt' correspond to my actual speed at any of thsoe times. As little as 2MPH while going at least 15, as much as 40MPH while going only 17-18.
It also cut off power to the controller each time this happened, even if the displayed speed was very low. I verified the cutoff speed is still set to the max KPH it allows; once this had happened half a dozen times or so I stopped and redid the mod to the wire harness that lets power bypass the display's control line and go right to the controller's "keysiwtch" input; I was in traffic and this was becoming a serious safety problem, especially the two times it would not cut power back in until I power cycled the system.
It did not have these problems again after redoing that mod.
First four miles was to the light rail, then rode the light rail to almsot end of line, got off and rode to a friend's house another four or so miles. Total of only about 5Ah used, of the 8 or so safely usable in the ammocan pack.
Brought charger with me in case I had to recharge and ride back, but he took me home in his truck with teh bike in the bed. Good thing, since the charger connector malfunctioned; I didnt' crimp it properly and it pulled out--I was able to fix it and start the recharge process anyway, but it teaches me another lesson, to not bet my ride back on being able to recharge at the destination.
On the light rail I had two conversations about ebikes. First was with a student learning electrical stuff; corrected a few misconceptions about ebikes and ebike law and such, but he was fairly interested in the bike.
Second was an older gentleman that suggested I put an alternator on there to recharge it while I was riding. I attempted a few times to explain simply that it's physically impossible to get back enough energy from this to even break even, and get the same range you would have without it, and that in reality you would end up with a *shorter* range by doing this, due to inefficiencies causing losses in each stage of power conversion. I don't think I got thru to him on that.
It's really hard to dissuade people from such impossible ideas! I suggested he come over to the forums here to read thru the discussions (including number crunching) that people have had about this subject. I dont' think he will visit; he didn't seem interested enough.
Eventually I mentioned that people have used pedal-generators to recharge the battery, but that even then it's more efficent ot run thru the chain directly. Then that people ahve put gas-powered generators on there for longer range than just the batteries, but it still takes fuel. We ended up joking about having Star Trek antimatter reactors on them or the Mr. Fusion from Back to the Future, as the only good compact solution that *might* someday be possible to power things without big heavy batteries.
On my second half of the ride after the light rail, going down Dobson, at one of the side streets there was a bike leaning on a pole and a few feet away a group of paramedics and police officers standing around a sheet-covered body on a gurney. There were no other people around, so I suspect the body was the cyclist. The bike appeared undamaged, so I don't know what actually happened.
Most poeple were actually fairly nice on the roads, considering their speed limits were 45MPH and the best I'm allowed to do is 20; most of the impatient people changed lanes and passed, rather than lane-splitting or roaring past me, on those stretches with no bike lane or with one only inches wide that could never really be called a bike lane (but is apparently intended to be).
OTOH, there were places where the bike lane suddenly and without announcement simply had it's left line go diagonally into the curb, ending it. Those were fun.
Always in places you couldn't clearly see that this was coming, too, until you were within a few car lengths of it--hard to plan where to go like that. Not really anythign taht stupidly done up in Phoenix, and this is Tempe which is supposed to be bike friendly!
All in all was an interesting ride, but if I could I'd rather ride the whole distance on the bike rather than do the light rail. Air conditioning or not, it's not fun to sit there and be jerked back and forth at each start or stop, listening to the babble of people angry about this or that, or hearing them spout off about something they know nothing about as if they did, or having phone conversations that ought to be private out in public. Definitely would be better to ride in the heat. I just have to put airless "solid" tubes in the tires on CrazyBIke2, so not to have to worry about flats, and then carry enough battery for the whole trip there and back (in case I can't recharge for some reason).
