Not long after I met the woman I'm now married to, we started into bike riding. At that time, she didn't want to spend a lot of money on a bike. I suggested that she buy a Schwinn Suburban [ladies frame] from Walmart. $130 for it. In the store, I rode it around while hearing the derailer clicking and clacking. I managed to adjust it to where it shifted smoothly. It's worked good since then, been about a year or so, give or take. Having read posts about the follies [and sometimes horrors] of department store bikes, I'm wondering if I should have her bike given a look over by a bike store. It seems fine to me, and she rides and likes it well enough.
