Beach Cruiser Bike for Sale

Hi! I am a freshman at Stanford and was hoping to sell my bike. I bought it at the beginning of the year and had the bike shop assemble it for me. The break pads were just replaced (2 weeks ago by the bike shop) and it includes all the safety measures to prevent theft. I bought these all from the bike shop: seat safety lock so it cannot be taken off, wheel locks so the locks cannot be stolen, a light at the front, and a large basket in the rear. I originally bought these bike for $350 on amazon and with all of the safety inclusions, I paid $500 total. It is in perfect condition, the only small flaw is a rip in the seat which could easily be fixed. Many of my friends have bought used bikes from the bike store and they tend to be over $300 without any of the additions. I will include the link to the original purchase on Amazon if you are interested in details. I am open to negotiating. Email at jdoss@stanford.edu for more details
