Uno Motorcycle

A motorcycle with one wheel? No, it just looks that way. The Uno has two wheels, side by side. It runs on electricity and is controlled by body language. The only controls are an on-off switch. To go forward, you lean forward. Lean further to go faster. The Uno was invented by 18-year-old Ben J. Poss Gulak. Motorcycle Mojo has the story of how the Canadian engineering prodigy built the prototype Uno. http://www.motorcyclemojo.com/articles/the-uno/

Where did it say it only had one gear? I would think it would have an automatic transmission built in there somewhere.

Also, I wonder how far it can go on a single charge, and how long does it take to charge? I wouldn't mind one of these for commuting on nice days.

I wonder if Dean Kamen would have ended up with something like this if he had listened to Steve Jobs and brought in a professional designer to work on the look of the Segway.

Tom -

The controls consist of leaning forward and backward, therefore there is no manual shifting. If you've ever seen a motorcycle with a (rudimentary) auto transmission, they are obscenely huge. This thing as half the size of the smallest sportbike I've ever seen, so it does not have space for an automatic tranny.

It's basically a Segue styled to look like a unicycle.

This is an old idea, although Bombardier never made a prototype that I know of.

it could have a continuously variable transmission. as rpms increase, roller weights/pullies expand through centrifugal force and cause the gear ratio to change. since the setup uses a belt with no fixed ratio, it is considered a single speed tranny. Not sure if it applies to this vehicle, but it's very common on 50cc mopeds and scooters.

It's direct-drive electric, no need for a transmission. Probably tops out around 30-35mph (capped for safety reasons I'd suspect). Unlike a segway though, you look cool riding it and would be much more aerodynamic.
