EHeh....
It is hard to say....the feel and the intention of the producer is indeed what you figure (same speed/output) and the (poor) bench test I did confirmed that, but I'm using the 20" into a 20"x4" 1/4 tires and the 24" into a 29" rim with road tires, so Have not compatible real world data to compare, mostly because the 2 bikes are totally different (a 13.5 kg fast road machine and an heavy turtle steel fat BMX).
Actually I'm testing the 20" with the Lishui sinewave (non FOC) ESC, It pull and climbs surprisingly....It tops out at around 33Kph (no pedal) in flat (with the KM Display wheel tuned for 22" wheels). Have not controlled it with a GPS or a CA Actually.
The shifting control works great. Still the Motor is noisy when in low gear.
Global consideration until now:
The KT controller (square) + combo seems less refined but works actually better in stock (better efficiency, less loud, less heat on the controller, the lishui works acceptably and at certain rpms range seems to work even better....so I'm confident to get a proper config....
The lishui Has a programming port (white silicon 4 pin plug) but I'm still looking where to get an interface; ALso the KM5S that comes with my XD motor seems to have a non standard firmware, since I'm not able to access the settings and system menus as i Did with another one some months ago, and as it is in the online manuals.
Today I've made a 17% climb (400m long 12.5% average) and it sustained that very well.
Remember that this bike is almost unpedalable without motor.....so the pedal contribute is really lower than with standard electric bikes....
I will post an Audio and video file as promised soon
Cheers
Oh yeah. I like the Latin. I think it means "Someday we will look back on this and laugh." Is that close?
PS hey Doc, the translation is right....Is a verse of the Aeneis of Vergilius, actually the most accepted translations include an "even" ("maybe, someday we will look back and laugh even on this") in fact it's seems a positive and optimistic sentence from an happy guy, but it was instead one of the things that Aeneas said to his desperate people in the exodus from a burning Troy, conquered by an "horse".....these verses was written almost 2000 years ago....
