If you were using 26" tires and hitting 8000 rpm; you could climb most hills at 28 mph in 1st gear, 2nd gear would give you 37 mph and 3rd gear would give you 50 mph. The drive setup would be 10-20; 24-48.

They work well but if you wanted a left side drive, you'd have to jackshaft to the right side to drive it's input. With the SA S3X every thing can be kept on the left side a second jackshaft wouldn't be necessary.

Not sure I follow.

Correct me if I'm wrong, but if you add a jack shaft, put the shifter hub sprocket on the engine side (left), then use the spoke holes to mount the sprocket that will drive the rear wheel, then everything will still be on the left.

I was trying to think of a way to use a 3 speed hub, as a hub, but mount the "shifting" sprocket on the left - just have to figure out a way to attach a freewheel on the other side for the bicycle chain.

The SA S3X is the only fixed geared IGH I know of. All other IGH's freewheel which is why they'd have to be installed with the input on the right side.

The SA S3X can be pedaled in either direction to move the bicycle forward or backwards just like a fixie can.

Ah, gotcha! Don't know much about the IGH's.

Found this. You can convert a 3 speed freewheel to two speed fixie with some machining. https://www.sheldonbrown.com/awfixed.html

Need to get my hands on one and see what it would take. I have a lathe and knee mill. Having a 2 speed center on my bike would be awesome.
