First of all, thank you so much Maelochs for your response and all of the information. I really appreciate it. A little info about me. I am a 35 year old female and I am overweight. I have been looking into bikes off and on for the past few years because I was interested in riding just for relaxation...sort of like a therapy lol. That is still the reason, but I also want it for exercise. My plan is to start riding just around the neighborhood and maybe back and for to the store. Nothing major. But eventually I would like to work my way up to longer rides and doing trails and things. Im looking to do a lifestyle change. I will post a few links here and maybe you can give me your opinion off bat before I go look at them.
Also I live in Denver, Colorado. So if you would help me w/ CL that would be awesome. I would like to stay in the $200 and under range other than the new bike I listed.
