Ha! That's the first time i've seen someone using a remote crank to turn an armless master one - other than myself, when i built this:
Looks like our front ratios are similar too (30/38 but i have 28/40), good way to control an otherwise long chain whilst also adding in a final drive ratio.
Is your front fender the wrong way around? Or is it too low otherwise? I guess it doesn't need to be lower, as your legs are out the firing line.. Looks fun, anyways.
