    Suspension Design

    Posted by Bob Dold on Sunday, September 17, 2006 9:22 PM

     

    The front suspension was designed using a layout skeych in SolidWorks to size the a-arms and locate each of the pivot points. The layout (shown below) was designed to minimize the wheel angle change (camber) and to try to keep the roll center locations close to ground level.

    The image shown below shows the completed model developed from the sketch layout above:

    2006 Schwinn Stealth – Donor scooter

    Posted by Bob Dold on Friday, September 15, 2006 8:26 AM

    In an effort to produce a lower cost drivetrain I plan on using the drivetrain on this scooter to power the bike, the Stealth has a gearbox whch I will connect with a chain to the rear wheel to provide the necessary gear reduction. I plan on replacing the batteries with a higher capacity set in order to get the desired range of 50 miles.
