I think...I might be mistaken, but I’m going to go on a limb and say that the torque of an electric motor is max at zero RPMs. In gasoline motors max occurs somewhere between 2000 and 4000 for the usual normal everyday automotive engine. For a diesel it is sometimes just under 1000 but usually 1500 to 2000.
I don’t recall the difference in power and torque output curves for normal variable speed electric motors vs freek drives (variable frequency motors), but I think the freek drives have superior low speed power. I know there’s less heat generated. I’m guessing a freek drive could really haul a$$ in a drag race if you had a computer modulating the frequency vs weel spin all the way down the strip.
I hope it's a strong limb, because I'm out there with you! The same horsepower at all rpm.
That's why the 0-60 speed is so quick, despite the bike's heavy weight -- max power availability all the time. Also easier on the drive train, since it can be designed for a single-figure constant strain, without torque variation and power pulses. The track times can be quicker with a motor that has less overall power compared to the liquid-fuel competitors, provided the bike weights are comparable.
