HOW TO PLAY THIS FILE: This is a frame-at-a-time Quicktime movie. When you hit the black triangle play button, it will play just one frame. Click on the button again to go to the next frame. Or, grab the slider and move through the animation as you wish.
(Editor’s Note: Here you can see we began to work on the issue of how to stow the front wheel, and what to do with the cranks.)
