actually the way i interpret it is...
sustained moderate/high speed reduces range. stop and go increases range... wonder if they are using regenerative braking?
I don't think Brammo is (yet), but this racer is:

I read a track-test review of the MotoCzysz E1pc (in MotorCyclist magazine; it doesn't appear to be online) that says the numbers are roughly comparable to an overweight 600cc sportbike... but goes on to say that comparison misses the point - the power that is available at any speed is completely unlike anything produced by any internal combustion engine - instead of a torque "curve," the dyno shows basically a massive rectangle of torque.
I'm no early adopter (though I would be if I could afford it) and I distinctly remember wondering why I'd ever want to carry a big old brick cell phone that had lousy reception, bad battery life, was hella expensive and was a poor substitute for the pay phones that were on every street corner. I'm glad somebody else did.
Electric superbikes are coming, and they're going to be one hell of a lot of fun.
