I have been in the process of losing weight and getting in shape for a month or so now, I started by watching my diet and purchased a gym membership where I go religously for an hour or so a day mon.-fri. I have been splitting my time between weight training and cardio first on the treadmill then I moved to the stationary bike and enjoy it so much more. I'm down 15lbs so far and I am considering buying a bike to ride the country roads around my house on the weekends but I don't really know what to look for. I'm 5'11" and weigh 334lbs and would be looking for something just to ride black top roads not off road, I have been told to look for good non-suspended MTN bikes with good tires/wheels I would be interested in a hybrid/Comfort bike also but I am oblivious to what brands are good or bad I would like to spend no more than $600 or so out the door. Can you guys or ladies recommend a few for me to look into?
