Hey guys! I am new to biking and looking to start biking soon. I live in upstate NY. Also new to this site so please forgive me if I have not posted in the right forum.

I was looking to buy a bike for myself and started looking at craigslist for deals. I ran across these two bikes around me for price I can afford to pay.

2013 Dahon Vitesse D3 - amazon.com/Dahon-Vitesse-Folding-Bike-Shadow/dp/B0067HK0KK - Seller asking for $300

2011 Dahon Mariner D7 - bicyclebluebook.com/value-guide/product/24977/ - Seller asking for $225

Or I could buy this new bike for $250 - amazon.com/8pk-Ballpoint-Pens-Black-Blue/dp/B00HJDRZEA

I was hoping on getting some feedback since most people here are aware of what to look for. I would really appreciate any help! I cant wait to start riding! Thanks for time.
