Me and my friend are planning on going on some bike trails in the area, and I need a bike fast. He's trying to lose weight and he needs a partner to go with. But it needs to be cheap. I am looking at these two bikes on Craigslist. Which one would be the better choice? Any other suggestions? We want to go on some trails with jumps (small jumps) and that are a little challenging. Not just a flat road trail. Thanks!
