I picked up a 1984 World Sport 49 cm. I originally picked it up for my wife at 5' 3" thinking that it would fit but the front wheel hits her foot when she turns. So, my nine year old daughter is tall and lanky...so for the past year I have been sitting her on it every few months or so to check how she is growing. I put her on it last week and she is so close! Her legs are straight out at the bottom of the pedal stroke so we need just a little more for her to fit...everything else is good she can reach the bar and use the brake. I have the seat slammed as far as it will go. I am so ready for her to go out riding with me...maybe by spring.
