I found a new Schwinn Tailwind for sale for $900. I am wondering about the bike and why it was marketed by Schwinn for such a short time? Even though it is new the battery is still around 3 years old. Would that make the battery less than stellar? Also with a small motor would it be effective in the Denver area rather hilly? Would love to hear from those that own one how they like it or dislike it and why?
