New Build on last years Krampus, Sram stuff. Gx-1000 cranks( boost) , 22-36 front, 11-46 rear. Boost wheels. Needs a problem solvers clamp to space the front der. out properly. Gx shifters, gx front and rear der. Really cool? Problem solvers make a clamp to mate the sram shifters with an xt brake below, 1 clamp, awesomeness.

Using that gear, that is the same as riding a bike or (unicycle) where your crank was attached directly to the axle of a wheel that has a radius 168 mm.
If your crank arms are 175mm, your foot travels more distance than your bike when you are in first gear.
You will have to spin pretty fast to maintain enough speed to maintain balance and directional stability.

I have the equivalent of a 50-20t crank * by having an internally geared 2 speed crankset. low is 2.5:1 reduction gear
* actually 54/21.6t AW3/ BSR Brompton hub used twice 15t cog _ 16" wheel.. [Schlumpf Mountain Drive]
R'off did the mechanical engineering math to use 7 speeds 2 x and have the % between gears as a regular 13.6 %..

I am not sure what size tire you have, my 700c X 37mm wide tires have a circumference of 2204mm. If I had a 22T chainring and 46T big sprocket in back, my gearing would be 13.2 gear inches.
