I spotted a beautiful blue Nishiki in a thrift store and am very tempted to buy it. It is what they call a Mixte frame. I have heard conflicting statements that this is a women's bike and also that it was designed to be unisex. Anyone know? I like the idea of it being easy to get on and off of since I am getting older and not as flexible as I once was. However I am a guy and dont want to be 'ribbed' about riding a women's bike.
