Answer found it can not stand on its own 
"There is an important note that we must stress about the conversion - the Noomad Kit does not make the trike stand up on its own. You still need to balance when riding and stationary. "

And this doesn't bode well for the kit:
"I got to try one of these kits recently.
First try was on a LWB. I would say it was not impossible to ride, however it was very difficult, and never felt even a little stable.
We moved it to a SWB not unlike in that video (mine is an r200 though, so not exactly the most awesome SWB ever). It showed me why the guy in the video seems all over the road. It is MORE ride able than the LWB but still unstable and difficult to control. Its hard to ride a stable straight line, and to me felt like it could become very very scary at speed.
Lastly I tried an upright MTB and I would say it felt ok at first, I was riding it around trying to get the hang of it and discovered that if you turn too far, the whole thing wants to jerk into a much harder turn, sending me over the bars and breaking my new Giro Bishop helmet (better than my head though!). This happened at about (estimated due to computer sensor being on normal front wheel) 10 mph.
I could not get my wife to even try it after seeing me struggle to make it work on any of the bikes I had to try with.
I would also NOT put any child, especially not my own on that front carrier.
With some significant engineering changes probably including a rake/trail adjustment. An adjustment that controls tilt vs turn, and a good steering damper, I don't see this as more than a dangerous gimmick.
Its also worth noting that for the price of buying a bike plus this you could just buy a real trike. I'd take the crappiest Performer or KMX (I don't know them to be crappy, they are just low cost) over this kit attached to an awesome bike."
