This could be done. I highly doubt we would be dealing with any type of patent infringement issues. It's very simple: there are belts out there, they have specific teeth geometries, our bikes have specific bolt hole patterns front and back, gearing is an issue of geometry (ratio of one gear/sprocket/cog to another), belt width and frame/cover clearance issues need to be taken into consideration. It’s a matter of getting the dimensions, drawing the stuff up (of course always considering manufacturability issues), ensuring you are using proper materials, finding a machine shop with the right equipment, buying some hardware and voila (spit).
Umm, now that I have gone through this thought process, $700-$800 does not seem all that crazy for what needs to be done to make these dam things. Perhaps I’ll have to do a one off and see how that goes.
