Agreed, I'm 5'8"-173cm and my knees are close to hitting my wrists on the Dove. It's rideable but the wheelbase is so short an endo seems probable. When I built my Dove up there were no 14" circular fenders to be found online so the ones on my bike are for 16" tires. They do the job well; I just bent the bracket so they were closer to the tires. I can see why the Dove is so popular in China. It's cheap, lots of aftermarket parts, smaller people, smaller living quarters, and well paved infrastructure.
