There is nothing wrong with those bikes. Why I used to have a Huffy that I rode across the Sahara desert and I never had 1 problem with it. My kids all have McKids bikes and are very happy, and we plant flower in the frames after they break, so they are educational, as well. You people must be a bunch of elitist rich-boys with your high-dollar $300 bikes.
