Mac 12T is too heavy for my new full suspension project, so I have some thoughts about Q128H. I'm building my battery myself so I'm not limited up to about 100V, but not lower than 67V. To make this task more interesting, I've limited myself to max 17A to play with, preferably less.
Speed is not the goal, I already crap my pants at 20mph(32Km/h).
I would prefer that it revs ridiculously high whyle climbing slow, to keep the mass and size on the low side. It will be oil cooled, maybe even externaly later on. In essence, I'm looking for a hub that is a light sub 3Kg RC motor wannabe.
The question is, does 48V 201 rpm Q128H have same 13.2:1 reduction as 36V 201rpm version? Or they just use lower gear reduction ratio and windings instead? Are those gears interchangeable? Any other gearsets that can increase this 13.2:1 ratio? My summerhouse is at the top of the mountain that look something like this, and I really hate pedaling. Or shall I choose the xiongda 2 speed and use it in 1 speed only?
Does 48V version Q128H use this (like Q128H 36V does):
or this(as the old Q128 does)?
Is this correct?
Reduction ratio: 13.2
Nominal Voltage: 48V
Hall Sensor: Waterproof hall sensor connector
Dropouts 145mm (135mm as a single speed??)
Cable Location: Left
Brake Type: Disc Brake, V-brake compatiable
Rotor alnico number: 16
