My girlfriend recently told me that she wished she had a bike so we could ride together sometimes. I want to buy her a bike as a surprise. She's 5'6" and of normal body size/type.
I am thinking a 54 road bike, and only have around $500 to dedicate to this. So thinking probably used, so I'll troll around eBay and the Classifieds until I find something I like.
Are there any female considerations that I should take into account?
Is there anything better I should be looking for?
Is 54 the right size?
Is this a bad idea?
