Anything from Walmart/Target or anything that is not a real bike shop is going to be incredibly low quality. Best off going on Craigslist and buying something (probably japanese) from the mid to late 1980s that was at one point a good quality bike. Get something with chromoly steel. It will be a lot more reliable and bike mechanics and you will be better able to fix it. It'll have all ISO standard parts.
