The fastest wound Cute would be the 24V/250W "328" Q100 which I believe has a no-load speed of 328 rpm @ 36V. This is the same as some fast wind 24V Bafangs and the mini GM. Russell has reached 29 mph on a fast road bike[700cc whl.s] w/ a 24V GM @ 12S. To reach 30 mph on a 26" MTB, you would probably have to have at least 14S.Haste said:so has anybody ran a high speed motor at 48v? Or go the 24v and went to 48v while keeping amps low? It should be as fast as bafang bpm correct? Im looking for a 30-32mph solution...
Of course, it wouldn't be able to get out of it's own way on any kind of hill and it's questionable how long it would last.
You could try "oil-cooling" it, like some here are trying out on larger motors, but the best way to reach 30 mph with a mini is to run two of them @ 12S.
