Looking to buy or borrow a bike for the summer 🚲

Hi everyone! I’m a Stanford student here for the summer (doing a research fellowship through the end of August), and I’m looking for a bike to get around campus.
I’d love to either:
• Buy an affordable used bike, or
• Borrow/rent one from someone who isn’t using theirs this summer
I’ll take great care of it and return it in the same condition (or better!). I’m on a student budget, so anything reasonable works — happy to discuss price.
If you have a bike you’re selling or would be willing to lend, please reach out! Thank you so much
