Gently used foldable bike. Extra light weight. Selling it because I upgraded to an electric bike. I had it checked at the campus bike shop and they told me it's in great condition and could easily sell for $450. The tires are new. https://www.amazon.com/Dahon-Mariner-Lightweight-Aluminum-Foldable/dp/B08TWQ77VQ?dplnkId=8543ecca-3624-4eb4-aa6c-8fe234ab08d4# Pick up on campus or in Mountain View. Price somewhat negotiable!
