I'm new here and I'm interested in buying a mountain bike for college. I'm not interested in a more expensive bike, as I'm mainly using it to trek from class to class. Also, bike thefts are common on campus apparently. The campus is quite hilly- and there are a lot of bike pavements along with the road
I found three bikes on Dick's Sporting Goods, which are all on-sale for similar prices. I don't know much about bikes, so any feedback on which is best would be greatly appreciated.
