I like this a lot. Bringing up so many hoon emotions from the old days. Being a big fan of the Akira bike, and having seen a few designs this looks to be the most practical and safest.
One thing: " Parking the bike requires an electrically operated center stand (there's no side stand) so you've clearly got to pick a good flat spot." Its begging for gyro stabilization, so give it what it needs.
A flywheel powered from the main drive can continue to keep the bike steady for a minute or so while the driver dismounts or lowers the mechanical supports. Gyro stabilization might offer the second benefit of being able to control a drift if things go pear shaped.
Also, I know the theme is economy, and nothing has to deviate from this. But placing the driver in front begs for the mother of all engines.
Maybe something rotary with a turbo, or a alcohol fed gas turbine. I'll be honest, the only thing I'd ever want to do sitting in this position is test the grip and upper speed limit.

It's a neat concept. Reminds me of the Tron light cycles a bit. Or the Akira bike.
It really seems like it should be a couple feet shorter, though. They seem to have kept the donor powertrain intact, and that makes it much longer than it should be.

Nice! Reminds me of a more polished "MotoLuge": http://tulberg.com/motoluge.html
Or a non-gyro version of the Lit Motors vehicle: http://litmotors.com/
Very cool.

Wait, this doesn't get as good millage as the elio? If that is the case I guess it being not fully enclosed creates some(i.e. a lot of) drag. Back in high school we had a class where we build an electric car and competed against other schools. Near our school we had a factory that produced single engine planes and they made a plastic coated fabric skin for the smaller planes to keep them light. I have no idea what it was called but they made us one for our car and it would go quite a bit farther on the same charge with it even though it added 35 lbs. We won every year because of this.
I really think a serious vehicle needs to be fully enclosed. This is fine for a street legal version of a snow machine or a 4 wheeler, basically something to play around on, but not to use every day or long distances.

I agree about the huge length, why not run gearbox/shaft drive along side the motor? Would not need a huge offset with the right engineering. As for parking, why not something like the several versions of locking dual front forks/wheels available on some (carving?) machines already? With separated front wheels, should be enough to keep it upright while climbing out.

80mpg is hardly "fantastic" or "impressive." Another recumbent motorcycle, the Quasar, was said to have similar fuel economy, and that was made over 30 years ago.

That is just so cool. I wouldn't want to spend a lot of time in urban areas but on the open highway it would be great. Two bad you cant pick up hitchhikers though.

What about the voyager made by Royce Creasy in the U.K.? a much better concept.

I think this is way cool. I think one could travel long distances since - basically - one is sitting down like in a car and not straddling it. I think side doors would make it even more aerodynamic.

Nothing new here and not a good example either.
I drive a low seat, low CG EV MC with just a 1' stretch so a passenger could sit low too for 78'' wheelbase IIRC, and it's just not smart go over a few '' longer than that as impossible to turn in close in normal spaces, roads. Just try to park it in many spots ;^p
His problem is picking the wrong too long motor/trans and it being in the rear forced the length. The only place for this is the freeway or a drag strip. Outside of those it's just a pain.
