You have to watch the video's to see just how clever this system is! The third or fourth one down shows a closeup moving schematic. It's really clever!
It looks like gear changes would be much smoother, and possibly more trouble free.
What it can't do is back-pedal braking which some chained bike have.

It looks like there are two one way clutches one on each side where you apply power from each pedal in turn, one going back, no thrust, while the other side is pulling, with thrust, so its left side thrust, slip while the other side thrusts, which then slips while the first side thrusts, etc. No slipping.
Looks like it'd slip a lot which wouldn't be fun for say going uphill or in the mud.

I'd much rather play with it in person first 🙂

Originally posted by ua41It all depends on whether this bike can be built close to or even cheaper than the standard chain bike. It so, you will see them up close when they hit Walmart and such.

One question I have is how would it perform as a racing bike, Ala the Tour De France?
