Taking a wild stab in the dark... I'm guessing not Eye-wink

I don't think so. I don't see it being able to be applied to duel suspension bikes without a very strong cable.

looks overly complex and expensive to manufacture

so no Smiling I think the chain is safe for now

All rational comments aside, That thing is ugly and comes with a certain "I refuse to be conventional because I am better than everyone" attitude. Nothing wrong with progress but simplicity wins in my books

Nice one Victorian Dad! That's what someone said about the horse and cart..

There is of course nothing simpler than the 400 (?) parts of a chain; the springs, bolts, pivots and other components of two derailleurs; the bearings, seals and other parts that make up a modern freehub; cogs; sprockets; and shifters! And then while we're at it front & rear suspension and disc brakes are pretty low tech items too.

Change? Hate it!

(Half joking Smiling )

So, I just spent all of about 45 seconds thoroughly and scientifically studying it's design and I can't see how you can get power on the upstroke, nor much other than the down stoke (hardly a hindrance with those pedals mind).

Excuse the eBay kiddy-comment but if this is the case.. epic fail!

no rear disc compatability! & just imagine the mess a gum tree twig would cause!!

"string bike" - not the most confidence inspiring combination of words I've ever seen. Laughing out loud

What happens if you break the string?

Imagine expending all that effort to design this contraption

As a mech eng I love this sort of stuff. Not practical, but I really appreciate the geometrical work involved in designing the crank linkage system.

Another left field design I can remember was a bike which used triangular shaped wheels but still maintained constant BB height.

Could be a few problems with this one though. It's pretty darn complicated. Gear shifting looks slow. The whole thing doesn't look too robust. How well it copes with dirt, grime and wear is a concern. I'd wonder whether there could be issues keeping the dual drive system matched after a bit of wear/dirt/gunk as it would kind of suck to end up an uneven bias?

I have to chuckle at the claim it's so much better because of the added ground clearance. Maybe I'm missing something but my pedals cause me problems way before anything else.
