I took it to the bike shop and they loosened some nut or bolt over the weekend. It spins fine now. What's nice about getting something at Walmart is the ease of returns. This is actually my second purchase of the same bike because the first one had a handle bar unfolding issue. The locking teeth weren't retracting. I also got the 3-year warranty for $25 just in case. It's too bad Dahon doesn't have the Vybe C7A with fenders for $400 at Walmart like smile.amazon.com does (with no taxes). Otherwise, I might've gotten a Dahon. Well, I still have a month left with the Walmart purchase if something else grinds my gears (pun intended).
