Hi everyone I need some advice. I am hoping to get into road biking and I have no idea what I'm doing. I used to ride BMX bikes a lot when I was younger, so i do have a good amount of general biking knowledge, but when it comes to road biking, im clueless. I am going to be joining the military in a year, so I'm hoping to not only do this for enjoyment but also as a way to do cardio training. my first bike will have to be used, or a low end new one (paying for college tends to drain my wallet), and I am really unsure of what to look for in a good bike, what some good brands are, etc. Any help would be greatly appreciated!
