Query: Mark, your review describes this bike very well

You are so right! I thought a $200 bike would last me more than a month! In less than a month I had trouble with the Front derailleur and my rear axle! I'm so pissed because like you said, I would have to spend half as much to get it working good!Schwinn Quality = Bad Quality
