This project reminds me This
good project, I’ll follow it too.
Personally what I’d like to see coming is a 3 speeds hub with something like 1:1 ; 1:1.35 and 1:1.75, on a 29/32" wheel with a shifting lever/trigger on the handlebar.
I’d only see a 4th speed under the 1:1 ratio for 36" wheels, for uphills, I don’t see the interest of a lower ratio on smaller wheels unless you want to use very short cranks, but very short cranks especially makes sens on ungeared unis, or on very light g29 wheels for road only riding.
The bikes use more accurate and efficient gears systems (thanks to the free wheel) with many gears, low to very high gear ratio, and you don’t see bikers with short cranks, right?
