If you are going to go with a Walmart bike stay away from the roadmasters they are cheaply and poorly crafted. All the bearings in the one i purchased needed replaced and there was a defect in one of the rims where the tire would not stay seated and nearly killed me and my daughter,

If you want to go with a department store bike then you should go with a Target bike. I have had no complants about the one i purchased and has lasted through many adventures and crashes.
