I am 6 feet tall and ride a 55cm raleigh rush hour. I finally settled on a seat position which is comfortable for me and honestly it's pretty high. I think the bike is too small, but I don't know if it's a properly sized bike would help any. Here is a picture:
My seat is actually a bit higher than in this picture, maybe an inch or so. My wrists and back hurt a bit when I ride for extended periods of time. Do you think it's worth it to sell it and get a properly sized BD bike or similar? Would those be too much of a downgrade? Also, any estimates of what I could sell it for in NYC/brooklyn?
