I converted my FWD lowracer to a crankfoward. It's singlespeed and compact at 38" in wheelbase. I maintained the folding feature as well. I removed 12" of seat/main-frame, narrowed the FWD fork, widened the rear fork, cut off the boom and mounted it into the seat tube position. Voilla, instant SSCFCFCF (single-speed, carbon fiber, compact, folding, crank-forward) or S2CF3.
I got the seat on sale at Nashbar. It's 9" wide and very comfortable. I don't care for the you-better-be-secure-with-your-manhood-pink color. I'll soon cover it with some black lycra. Another benefit of this type of seat is that a padded crotch isn't required.
