Recently sold my road bike due to lower back. Now orthopedic and chiropractor suggest start riding a bike in a more upright comfortable position to help with sciatic nerve. So anyone have suggestions. Looking at my LBS and seems like Trek Verve or Trek FX. They also have Giant Escape but didn't care for Giant road bikes. Anybody with some advice Or possibly same back issue that had success. At the moment can't go test ride and am looking for advice/suggestions.
