Looking for help on the right bike for a senior.
I am a senior looking for input on a reasonably priced (>$400) bike to use as part of strengthening regimen after double hip replacement. I am 5'10" and 240 lbs. and fairly strong, but haven't been on a bike in many years. Most of my riding will be on the street but we also have some well-maintained trails in the area I would like to try. My research points to a hybrid or a 29er. What features are most important for me and what makers are likely to offer the best fit for me?
