E bike conversion with belt and pulley

Update Jan 2018. After repeated attempts to get a belt driven ebike working and having at least 2 belts break, I have come to the conclusion that it's simply not worth it to go belt driven. Just get a hub motor and be done with all the headache and time wasted.

This is a parametric version of the pulley used in StatonFrames pulley. Now you can choose the number of spokes and locations of the zip ties and stuff for you specific bike.
