I bought it at June 5th, rarely used it, less than 10 times.
It's in excellent condition, almost always parked in door.

It's purchased from bike connection, 330$. They can refund you 40% if you trade in the bike before June 2012, and if the bike is in good condition. I can give you the receipt.

It's a mountain bike and is perfect for woman. I really like it, sell it only because i'll leave here next weekend. Ask for 249$.
You can see and try the bike after 7PM on weekdays. I live on Stanford campus, EV Building 4 next to GCC, My phone number is 818-854-5086
