(To the makers of the Craigway)
Just a thought . . .
I looked at your video clip and I noticed something. You still were having a hard time balancing on the platform. (This is just a suggestion but . . .) I would try to lower the center of gravity on the machine a bit more. Most importantly put the platform under the wheel axle.
I don't know if this has been mentioned before, or what problems others may find with this idea . . . its just an idea.
Good luck
