Neat! That's an amazingly slick and elegant folding process.

Doesn`t show him actually peddling the bike. Where is the chain to drive the rear wheel.

Something not right here.

Good point – I hadn't noticed that. It may be a "concept design" at this point, but it would have been nice to have that noted.

Where is the chain to drive the rear wheel.

It's a Chainless Direct Drive, fully enclosed beveled gear system. Rotatably mounted within the housing is a variable rate transmission, eliminating the need for derailleur type shifting.

Seems that anyone who can solve a Rubik's Cube would be able to fold and unfold the bike without much difficulty.

Looks ideal for traveling on trains, planes, subways, ferries, etc

Nice clip, Lexica.

Thanks for the info, Steve. Any chance you could point me to more info on chainless drives? I was looking at the video, trying to figure out how the cranks might be transferring power to the wheels, but (based on the video) couldn't figure out how it works.

This site has info on the D-Drive System but doesn't have a diagram which shows how it functions.

I am a Bicyclist and came across this innovation several years ago. The information provided, showed that the Enclosed Direct Drive operated very much like an Egg Beater, as viewed in a horizontal aspect.

I was tempted to buy the bike but the technology, at that time, wasn't as sophisticated as the one you clipped....
