Anyone who have drive test on Sinner Hilgo,I had seen some videos online but was not really detailed,the gearing system sounds good.
I need CAD model of the gearing system if anyone have or share more photos.

That's great. I'd have to be shortened with a spring return for a FWD hub with wheel.

Yes, cantilevered. I have an idea. I'll work on a steel prototype today. Yours can be carbon.

... I made a proof of concept cantilever fwd derailleur, it shifts. Needs a lot of refinement. I annealed the spring when I welded it, needs Hi-low stops, cable, tensioner, chain closer to the steering axis....I wanted to use only one derailleur idler, but needed two to get enough chain wrap, don't have gravity helping.

It can't be push-pull like the video because of wheel clearance, needs a return spring. The spring will be reversed, pushing the chain inboard.. How much cable draw does a grip-shifter have?
