Used Trek Skye S black 13"
Cute and affordable -- very lightly used, great condition! Excellent bike for a small person, even at it's 13" size, the slight step-through drops the stand-over clearance as low as it goes for adult-size bikes.
Current tires are decent and not warn, so we left them on despite being nobby. An inexpensive upgrade would include placing 26 x 1.5 slick tires on this one for better city riding.
