Hello; I think you can get different sizes in pretty much any style bicycle now days so there should be no restrictions on the type of bike. Does USA made make a difference to you? If so there are some USA makers of bikes.
Mountain bikes can be pretty from basic to ones with complex suspensions both front and rear. I do not race down dirt trails so the suspensions are not so much of interest. I have come to like a suspension seat post and front fork suspension.
Light weight and nice components will equal more cost which will make such a bike a target for thieves which can mean the need for a very heavy bike lock which makes the bike heavy again.
May I also suggest getting a decent helmet, a reflective vest, some lights, two water bottle racks and a small set of tools you can carry. I also carry two tubes and a CO2 inflator with a few co2 cartridges. I also put a rack on the rear of my bikes. Might ask for some of this stuff when haggling over the price of the bike once all the bike price discounts are used up.
Hey Jeff,
Right now USA made isn't important to me. I want to go out and do a few trails and decide I like it, and commit. I know myself, I could very well be over it fairly quickly, So I don't want to dump heaps of money. However, racing down dirt trails is exactly what is appealing to me so I will invest in a good helmet first, and find out how much suspension I want. I suspect I'll start with a good seat lol. I'm also starting to wonder about how to equipment to bring with me. I hadn't really considered tools, or a CO2 inflater. Between that food, and water it sounds like a lot. The park I'm interested in trying first has an 11 mile trail, so I'm guessing I'll need it all at some point. On top of it all, the bike will be strapped to the back of a Camry, so I'll have to figure that out too.
