My only comment is why would you need 24 gears? On a 500W 36 volts system I use only 4 gears on the cassette and on a 750W 48 volt I basically use 2 sometimes 3 when riding?Just not sure about reliability. Not much at ES either.
Curious, grade and distance? With my converted Elite Trail I can keep an 18 MPH pace with moderate pedaling at 6% grade 44T/16T. Whether or not it's accurate the watt meter on the C965 display indicates 500-600w draw on a 750W 48V BBS02.But mostly because I'm looking for a system that will assist me up a couple thousand feet of climbing. That way I can finish the remaining 2000 feet on my own after the battery gives out.
Looks like an interesting ride. The average grade is 5.2%. I saw some grade over 8%. Since I've never ridden 30 miles essentially going up grade for a majority of time it's hard for me to know at what point I'd be physically exhausted. I do regularly ride 26-30 miles with significant grade changes but riding a constant incline is probably much more demanding (no break). Knowing what my 48V 750W BBS02 can do, I would probably be able to ride the majority PAS level 3 or 4 in 5th gear (assuming I didn't fold). The more severe grades in 4th gear. I'm pretty sure the issue that I'd find difficult is the heat. I'd be much happier up around 6,000 feet. My combined weight is 230 lbs.Mt Lemmon in Tucson AZ.
