Friendly1,
We should stop quoting those numbers (230/270), they are wrong. I put my hopes in them, but in fact rpm specified by the vendor is in fact accurate. I bought them and measured them myself.
because the 230/270 numbers are wrong, I went out and bought a 3rd motor.
The following were run at 36v on 26"/700c wheels
201rpm - good for 18mph unloaded, 15 loaded (happy at 16-17)
328rpm - good for ~30mph unloaded 20 loaded (happy at 25 mph)
201rpm 24v (giving 300rpm) good for ~23 (estimate) unloaded, 20 loaded. (happy at 22mph)
Those numbers are off the top of my head
I haven't measured the 201/24v unloaded, I should do that. But the three Q100 I have are indeed running at 200, 300, and 328rpm as they should.
If the 328 motor in fact did 270rpm, I wouln't have had to go out and buy a 3rd motor. Now I have a spare. :-O

Does anyone do a 250-270 rpm small geared hub motor (~250W)?
You have one apparently. The 328 is 270rpm. The 201 is 230rpm. The q100 numbers are just to compair to other makes, it is not there actual spec, it's just branding.
Why not a Q100 cst, It don't really need to be a 140 unless it is actually different. Explaining why there is not both a 201 and 328
Edit: Sorry.. Misguided post there. Both 201 and 328 exist, although they are just selling the 201. I guess it is a Q100
