I am looking for a good, strong, sturdy, reliable bike to use for building a motor bike, my budget is $300, I was going to buy a great bike off of craigslist for $60 but it got sold, I am now looking for one that is sold from an actual retailer (walmart,target,etc.) I know there won't be many out there since most of the frames on them aren't strong enough but if there is one you used or one you think will work I would like to know! Thanks
