I was gonna say it looks like the motoczysz bike.  But I guess there's a reason for that.

Zero Emmission IMO is a misnomer unless they are getting their  electricity from renewable sources. The electricity to charge that bike came from a powerplant that was making some kind of emmission, again unless it was exclusively solar, wind or water powered.

It is a great looking bike though....

Granted, but even if it comes from a coal-fired powerplant, the CO₂ emissions per mile ridden are low enough to make it an ELEV.

That said, can someone 'splain to me why it needs a clutch reservoir?

I was wondering the same thing!

F/R brakes, maybe? so there's no foot ctrls?


:edit: n'mind, I can see the MC res in the side shot...

Rear brake, I assume?

A rear brake reservoir is visible in the side-shot.

That glaring design flaw aside, I'd still ride it.

Maybe there is a clutch so that you don't have massive engine braking when you roll off the throttle?  That'd make sense.  Many racers use the clutch to fine tune the power to the wheel.  Just throwin' out ideas here.

[Buckethead]

That's definitely plausible.

I kept wondering why you'd need a clutch to start out since the motor isn't turning unless you want it to, but I hadn't thought of the engine-braking aspect.

[Drunken Monkey]

It might have a clutch to help the electric motor get started:

Electric motors consume frightening large amounts of current when they first get rolling. Ever notice the lights dimming for a split second when your clothes dryer first starts up?

Possibly the clutch is there to help the motor spin up that first little bit. It's either that, or it's there to keep the bike's feel as similar to a "real" bike as possible.

And there's zero engine braking on an electric motor. Well, not unless you build in regenerative braking into the circuits, and AFAIK none of these guys have done that.

'splain please.

This is comin' straight outta my ass, but I think the internal combustion engine is based on intertia:  push a piston, make the bike go.  The whole time the piston is resisting movement, which is partly how you get engine braking.  I would guess an electric motor just spins in circles, so there is little resistance, and no significant potential for engine braking.

Anyone buy that load?

IIRC, weren't the mission one guys planning that? there was a brief write up in motorcyclist on their bike, and the TTXGP

That's my guess too.
