I purchased this bike for Christmas 2012 and enjoyed it for two weeks before the left side pedal rod broke off while riding. I was riding up and down my neighborhood on paved surfaces, no hard terrain, just smooth concrete. I liked the bike so when I exchanged the bike I got the same bike hoping it was a defect on my bike. The second bike had the exact issue plus the right side pedal fell apart. I had the 2nd bike for one day. I did not do any rough riding. I rode my bike on paved surfaces. There is an obvious MANUFACTURER DEFECT because both bikes had the same exact issue. I was fortunate both times that I didn't fall off my bike and get seriously injured. This bike is a piece of junk. Very disappointed in the quality of bike that Mongoose produced.
