I have 2 Trek 220 boys/girls size mountain bicycles in excellent condition. They are exactly the same except for the color. One is red and one is purple. 24" tires, 21-speed. Asking 135 each or I'll let them both go for $250. These bikes retail for $375 brand new. Trek is a top of the line company when it comes to bicycles. These bicycles are sized for teenage sized riders. PM me if interested or if you have any questions about the bicycles. Trades also considered.
