Oh Gizmo!
And a little marketing advice for the man ... if you really want to sell plans for something, do not include the following three things in your video:
1. The fact that it has no seat. (I do love, however, that he left out a seat because he thinks others will be intrigued by the frame.)
2. The fact that you have to reach behind you to control the throttle.
3. The fact that you have to get out and push if you want to turn around.
