Still no problems to report. Since this mod makes throttling around not pedaling, and running up through the gears like a motorcycle easy ( even zooming around standing up in the breeze not pedaling). I was experiencing some loss of range concerns. Also it doesn't coast as freely pulling the chain around all the time. With a 24Ah battery range testing is a bit of a chore. But riding normally I can get my expected range. Normally for me includes full throttle takeoffs in traffic and a couple bursts to 30mph. But mostly 15mph PAS1/5 and 20mph PAS2/5 riding. Strong headwinds here require PAS3/5 or even 4/5 and really consume the battery, so I had to wait for a still day to do this test. I din't get too technical with this. A 36 mile loop the 4 bars on the display dropped 1 bar 1/3 of the way back, and only dropped the 2nd bar 1/2 mile from the end. My 18Ah battery never made it to the turn around w/o dropping the first bar, so it's about the expected range. Living near the ocean range is always negotiable anyway.
Something I noticed on the test stand is that when running up through the gears using the throttle, when you upshift lifting the throttle (coasting to shift) and moving to a smaller cog always puts some slack in the top run of the chain. Multiple gear upshifts cause more of this. 2 gear upshifts are actually pretty common for me. The motor has enough RPM and enough low end torque that shifting up 2 at once saves an extra shift that can confuse following traffic. Also the motor can go 140RPM and I can only do about 100. I need 2 gears up to get back to the range of my own cadence. So full throttle launch, 2 gears up for momentum, and 2 gears up for cadence is common. With the recumbent chain management this has not been an issue. It's possible that this was one of the situations where I previously had zip tie breakage that the cause wasn't specifically known. This is a situation where the strornger clutch type offroad derailers may help. Since I'm all vintage Rapid Rise/ Revoshifter, and not having any issues, I'm not going to test this myself. Who knows maybe some users won't need the extreme chain management solution that I do.
I didn't get very technical with the battery measurement because I never bothered to do that before, so no really accurate comparison was possible.
