Looks like they're shopping for sponsors in a crowdfunding effort.
StepTwin Bike - World's First Bionic Stepper Bike!
Seems to me like something peculiar is going on. No one has ordered the bikes themselves, but 2 people have bought the upgrade to string drive, and six people have bought fenders.

Mmm, maybe better avoid it; Firefox gave me a scam warning on one of the pictures that wasn't showing up.

The more I look into it, the more I want to buy one, if only to see just how it works, which is something none of their videos or pictures clearly shows. Of course, if I could see one without buying it, that would be better--and might convince me to hold onto my money.

Look waaaaay down on this page--they did their homework:

Non omnino gravis
I think the state of cycling can be fairly well evaluated by the fact that StepTwin has raised $8,700 in 3 months, while the SpinCiti e-commuter bike has passed $400,000 in ~40 days.
People don't want a bike with two drives, that you "pedal" by looking silly. They want one that will go 30mph for the effort required to go 12mph.
That said, I'd like to try out the stepper thing at least once, if just to satisfy my own curiosity. Being limited to 18mph makes it pretty much "not for me" in the long-term.

I can't for the life of me figure out why this is supposed to be an improvement on a chain drive. One of the main reasons pedaling is so efficient is that the motion is basically slightly modified walking/running--our legs are evolved to come down in front of us and lift up behind us. This substitutes a motion where the downstroke and the upstroke are in the same position. Given that I can't think of a single human activity that involves doing this under load for extended periods of time, I have to suspect that this is going to create some unanticipated problems, but even if I'm wrong about that, is there any reason to expect that this motion will be any easier than conventional pedaling?
Mechanically, this is a dual drive vs. a single drive. I can't believe that a dual drive won't be heavier and more prone to failure just due to complexity.

Yh, they do give credit but on the first link they were trying to sell this stuff as "tHe FiRst biOniC sTepPeR biKE"...
Of course if you want the real walking + cycling experience you need to get one of these monstrosities...

Anyway, you can build a model of one of these yourself, without the cycling part:
