Re: Newbie here
You've come to the right place. If you want to stay cheap, the Huffy Cranbrook from Walmart is a common entry-level bike. Or keep an eye on craigslist, where you can probably find a better bike for about the same money. A Chinese two stroke kit will also be cheapest, but they have their problems, so buy from someone you can get good warranty service from. You'll certainly have to mail order that, but it's not such a big deal.
