    I suspect he means the step-down gearbox. The Empulse, Lightning, and MotoCzysz all run high efficiency, high power motors. This means small, liquid cooled, and turning HUGH rpms. You are not going to get that to the rear wheel in one step.

    ummm... are you speaking from experience/firsthand knowledge, or conjecture? I know a little about the motors they're running, but wasn't aware of any "step-down" gearbox or what I'd call huge RPMs. Hell, last I knew they weren't even dishing what motor the Empulse was using, specifically, since they hadn't really decided yet. Did I miss the memo?

    Sorry... it's a geared reduction in a housing - hence "gearbox". The Empulse RR race bike is still direct drive.

    The motor on the empulse looks like a PMS 156. http://www.perm-motor.de/index.php?i...on-motoren&L=1

    This would make sense as the enertia uses a PMS 120. Hopefully watercooled

    Controller wise my money is on the new-ish Sevcons.

    Brammo may make the "battery" but I seriously doubt they're manufacturing cells.

    Cell wise, not valence. I would guess something like kokam or A123 pouches but anything in that ballpark would make a 10kwh 420lb bike cost over 14K to keep a good margin. Unless of course brammo's buying in huge bulk or losing money on every bike sold.

    The Empulse is a cornerstone for Elmoto.net folk because for the first time, it will be cheaper for us to buy an awesome electric motorcycle than it would be to build one. No other bike on the market can do that for us, which is part of the reason we exist. I suspect over time ELmoto will be less about hardcore converters and more about softcore modders to their already electric Elmotos.

    Lightning and Motoczysz run with gear reduction.

    On the othe side of the bike there is a chain motor to jack shaft then the sprocket shown on that picture is one of the final drive sprockets

    Those videos are great and frustrating to watch after the end of the race season ;D
