Electric Ninja

There have been some pretty significant changes on ZX-E as of late. I'm going with dual k91-4003 6.7 inch series wound DC motors now. These are smaller than the 8 inch diameter motor I was originally going with. I completely redesigned the motor mount and managed to incorporate the battery mount into it, which at the moment seems like an advantage as far as simplicity and space management goes.

SolidWorks model of the bike frame and powertrain Alex and me drew up:

The finished mockup of the motor mount, the stacked battery mockup, and the controller all in the bike allow us to see how exactly everything will fit together and make sure the gas tank will properly fit on the bike. Mockups are definitely key before the mount is fabricated, because any slight miscalculation in how the design fits inside the frame could call for more than one visit to the water jet. Of course this would call for additional manufacturing and material costs.

The project is really shaping up and we've finally settled on a design that is simple and effective.
