I will get my 6 year old niece to try it, I will just tell here to hold on tight, and I will tell the guys to be nice and NOT JERK the bike!!!
Which is exactly what the bike does.
Looking at the video, you have NO balance and you almost fell off what the guys picked up the bike.

I don't see the complexity of the situation here. I bet you I can do it too even tho I have NEVER driven a bike in my life!!
