The bike was in good working condition, though the gears and chain were a bit rusted and the gear shifts were a bit off. Though I do not have the serial number, there were distinguishing features: 1. The seat has some black tape on it covering a few splits in the seat. 2. The gears are a little rusted. 3. The petals are an orange-ish color and were kind of spikey. I don't think they belonged to the original bike. I think they were a modification. 4. It was a smaller women's bike frame so it had a dropped crossbar. 5. These might have been removed, but there is a gray kryptonite U-lock on the vertical seat bar that's a little off-center, and a front and back. 6. The handle bars were flat. 7. There was a 3-gear side and a 9-gear side on the handles. 8. The wheels were thin (80-100 psi). Not mountain bike wheels. 9. The picture I uploaded is not of the bike itself, but it does look very similar. 10. It was fairly light. I think the frame was aluminum.
