The proportions don't even remotely work. For it to work with no head tube and the seat so close to to the smaller wheel, that would have to be a 36" or so front wheel. I've got one here, it's a bit unwieldy and too big to carry it hanging from your arm the way pictured on their site. Even if you assume the pedals are just decoration, there's no reason to put them way up at the height of the axis of the rear wheel, look at a picture of an adult on a unicycle where the cranks actually need to be at axle height and it becomes obvious that would take a far taller seatpost than pictured. Essentially their pedals are too high to use, but if they're not going to be used then pedal strikes aren't an issue and they could just have low moped running boards.

Seems like this was sketched by an artist who's never ridden any sort of cycle device - notice no one on their "meet the team" lists any familiarity with any sort of cycling at all; you'd think a bike company would have at least someone who'd pose on or with a bike...

The whole concentricity idea is silly anyway; it forces a large diameter wheel which is an immediate portability issue, while yielding a very narrow package, which isn't all that much an asset, and then you actually sit over the small wheel leading to worse ride quality than wrangling that big one on and off trains and busses should earn you. If you dispense with or fold the pedaling mechanism, you could fold two 24" wheels beside each other and have decent ride quality in a still fairly narrow package but with a maximum dimension that will fit in a train/bus overhead luggage bin where this would not remotely.

If they want to argue that the idea actually has merit, the most obvious thing they need to do is build one up with their proposed proportions using ordinary off the shelf spoked wheels that let the bike function, but not fold (putting cranks inside a spoked wheel's circumference but not concentric with its axle is a problem that Huni-Rex for example solved using a chain on each side, or they could just make a purely electric prototype - though trying to put them there is one of their more obvious mistakes). Actually get on that and ride it, and they'll realize the proposed design is not going to work well.

Here at least is a picture (I suspect render/photosohp - notice the valve stem that wouldn't survive a single rotation) that reveals the proportion problem:

Notice where the seat is compared to where it needs to be?

And of course articles just get generated from a press package without any actual *thought* put into considering what has been proposed.
