I finally got around to borrowing a scale to weigh the battery. It came out to 3 lbs, 1.9oz. So the weight is actually closer to a 13" MacBook Pro than it is to an iPad.

zro-1 said:This may be useful to the rest of the forum: I was able to decipher the info printed on the motor casing. Here's what the motor reads:
AKM17062901002
AAD3620A
H
AKM = the manufacturer, Akiema (or however that's spelled)
170629 = the date of manufacture (2017-06-29)
01002 = The motor model and version (0100 = Q100, 2 = version 2)
AAD = I haven't been able to figure that out yet, but I believe it is the code for the style of gears/brakes the motor can use (freewheel + disk/rim brake)
36 = 36 volts (yeah, I'll follow that :wink: )
20A = 20 amps
H = the H-series of the Q100
Papa said:My error for not sharing an ol' timer trick for overly tight fasteners - Assuming your Philips head...;
Take one of your unused or cheapie Philips screwdrivers and break-off the plactic handle. Now use the bare Philips shank & hammer to gently, but sharply tap on the offending screw's head (just envision the screw as a nail and you're seating it). Go easy 'cause It doesn't take much to free it.
Papa said:I certainly understand your frustration IDing specific differences between various generations of Cute motors. But it's vitally important that we avoid replicating assumptions. Among the many internal images I've seen, I have noted many obvious changes between the 1st gen Q100 and the later Q100H. [edited for brevity]
Ratio Formula I used... https://woodgears.ca/gear/ratio.html. (scroll down a tad)
My biggest concern... Is the results I get when I twist the throttle. Dissecting the motor blesses me with the knowledge of what I can and cannot do,... to improve the end results...zro-1 said:.My bigger concern is why BMSBattery says that this is a 12:1 ratio motor when in fact by both of our measurements, its only an 8:1 ratio motor.
Papa said:I'm also seriously pondering the phaserunner, so will be interested in your numbers. Thank you!
That doesn't seem typical of a 26"-700c/328. Any chance you monitored speed numbers? Top speed maybe on the level?zro-1 said:I took the bike for a test ride today since the motor and Phaserunner can both operate sensorless. It runs quiet and cool. I went up a pretty steep long hill and the bike kept its speed up very nicely. The motor wasn't much warmer than ambient temperature.
zro-1 said:Papa: you mentioned that you were interested in seeing my Phaserunner settings for the Q100H. This is what I've settled at for now. I might tweak things once I can get my hall sensors figured out.
