NB if you gear it High enough like the 54t chainring turning the 12 cog the GI of that 16" wheel is.. 72"
now put that cog combo on a sturmey archer SRF5(N)5 speed Hub and that gear is 160% higher ..

The BSR takes a 13t Cog and its High is 133% overdrive.. 88" now with the current spider crank any 130 BCD chainring will fit
How about a 60t?

Though you still have to contend with that Thick, Damp NO LA Air Resistance that wont voluntarily move out of your way.

You will automatically be faster in Colorado (or La Paz) at a lower air density
