Looking for opinions for a cheap Mountain bike. These will be for my wife and I. Will be used for 95% hard surface roads trails etc. no jumping, stunting etc. Looking for full susp. and not sure on brakes..disc or conventional style. Walmart has some decent looking bikes between $80 and $150. Target also. Costco has a nice Schwin with disc brakes for I believe $299. A cheap China made bike is fine for us as we will mostly just be putting along our subdivision roads. Any suggestions?? BTW checked out Craigslist..used bikes seem about the same price as new ones.
