Hello, im new to riding, but with the cost of gas and my health in mind, ive decided to take up riding. I have some knee problems, but with braces the problem is minute. So, my question is, what style of riding is easiest on the knees? I was thinking about long distance riding. We have some LONG flat country roads near my house that look like a very nice ride. What kind of bike is best for this? (technical names please, to make it easier to search for them). Is there any hope of loosing weight if im doing pretty much all flat roads? Thanks.
