I agree on the Schwinn Collegiate 3 speed recommendation. I found one at a thrift store for $10.00 & bought it just because every other Collegiate I ever saw was a 10 speed. Someone had altered it by adding a set of chrome drop bars & levers to fit but otherwise it was flawless. I rode that "Green Machine" on my work commute for a while & found it very comfortable & quite fast for such a hevy bike. Eventually gave it to my Grand kids & those boys haven't been able to break it yet!
