Ok, in my on-going endeavor to decipher BMS Battery's unbelievably obtuse listings of motor specifications I've been doing a little digging. This time I've got the Cute Q[X]100 in my sights.
Recent reports of the 201 rpm "slow wind" reaching low/mid 20's mph on 12S Lipo just doesn't jive the conventional wisdom, which would have that wind being a "Euro-spec.", 25 KpH @ 36V motor.
There is remarkably little out there, considering that one would think that BMS Batt. must have sold 1000's of them.
The best I could come up with was a passing reference by Lynchy[now more familiar as the guy with the red cape and the big red C on his chest.]. He estimated an early version would spin 220 rpm @ 39V, which still seems too slow for the reported real-world speeds. I'm thinking that it must be closer to the 250 rpm @ 36V of a MXUS or the small Bafangs[which incidentally BMS Batt. also lists as 201 and 328 winds.
]. Sorry, we'll have to wait till someone bench-tests one to get the real number.
I didn't do much better with the 328 rpm "fast wind" motor. But I did find one report on a German Ebike forum where the owner reported 26 mph[i converted this from KpH]on 36V.[26"whl.]. This would be around 32-33 mph @ 48! I'm not sure dual Q100's could reach that[1100-1200 watts]. That would be one fast mini motor ride if it could be done. At any rate, I reckon that 328 number is at least one that BMS B. got right.
Why do they do this to us? It's like they pulled some flunky off the assembly line, sat him[or her]in front of a computer and told them to play around with the keys.
I guess the Mysterious East will remain mysterious.
