A Wood Model Reveals: How to Understand the Self-Adjusting Seat on the Morphing Handcycle (choose full screen, and set view mode to "slide")
(download)
(Set viewer to "SLIDE" mode shown on lower left so animations will work)
This Powerpoint presentation and animation uses Alan Ball's clever and low-cost 1/8 scale wooden model to let us see how the seat bottom and seat back magically change angles to correct for tilt when the bike morphs up and down. Very cool, and it really works! (Note: this is a re-post using a PDF format from the the original Powerpoint)
