This is my first post. My doctor said go ride a bike. For my leg muscles. I'm sure an electric bike would help all around but they all look good on line and I'm sure some are junk. But, how do you tell. Perhaps some one here has already had great success buying a low end bike, and some have regrets. So, any information or suggestions would help. I live in Tallahassee in a neighborhood that has hills and flat streets where I could ride. I may be 84 but am in good health, far from senile and am very computer literate. Thanks in advance for any help I get.
