I think I'll get by with the little amount of threads for the bottom bracket bearing cup jamnut for now.
I put the wheels, crank, and kickstand on and weighed it. It was 23.74lbs as shown in the pic below. Over 6lbs of it is from the steel rear wheel/tire assembly
. I can upgrade to lighter stuff after I prove out the design, my goal is to be around 35lbs when done.
