that's pretty cool i would woder how load it would acually be in person. also it would be a great addition to an xtracycle

That is a very cool thing - I like my legs - but for many people, that is a great gismo. The price is pretty reasonable too - about 400 dollars.

I don't have flash player here on my work computer, nor can install it....what does this thing do?

from the pic im guessing it gives off mosquito fumes when you ride so they dont eat you alive?

It's essentially a wheel with a gas engine inside. Pretty clever. Supposed to do 20 mph max on flats. Since you can also pedal, I don't know if you can exceed 20 mph on flats by adding your own power to it.

it would have been nice to have specs on the capacity of the "fuel bottle"

Other than that, it looks pretty cool.

I could see someone putting this on a touring bike, and hooking up a 1-gal tank to it via the front rack.

So much for the human powered aspect...

Just another motorcycle...
