Chalo's recent post about a hydraulic bicycle reminded me of an oddity I saw at the local bike shop about a month ago.
Alas language barriers prevented me from asking a million and a half questions about the oddity in question and since I had no desire to buy it I wasn't going to bring someone in just so I could ask questions and leave again.
No chain.
And it had the word CHAINLESS blazoned on it in about 5 places.
There was a bar of some kind that went between the pedals and the back wheel. And that seemed to be it.
Any idea how they might be powering it?
Should I go back and take a in depth look even if it will annoy them because I have no intention of buying it?
I wonder if it is like the motorcycles that are shaft driven.

It is a shaft drive. It has a bevel gears instead of chainrings and sprockets. A shaft connects the two. It works much like the driveshaft of a shaft drive bicycle. Gear changes are accomplished the same as on your bike - a shimano Nexus hub.
It's all pretty simple, but adds considerable weight to the bike (despite any claims otherwise).

Shaft drive. Not unusual actually, people have been making "chainless" bikes for a long time, but they've never caught on. Chains, so far, are the most efficient way of transferring power.
