Mockup

Once a design was picked we built a mockup to get the needed measurements to start the actual designing. The mockup was a crude assembly of parts placed together quickly to get the overall shape. The intent was not to test functionality but to get overall width, length and height dimensions, as well as seating position and lever stroke length. From the mockup we changed our initial design by angling the seat backwards so that the operators weight would provide resistance during the pull stroke so as not to necessitate the use of restraining straps. We also agreed that the initial designs 8” rear tire would be too small. We also checked the ease of entering and exiting the trike with the use of a transfer board.
