I'm 36, weigh approximately 330lbs. My highest weight ever was 464lbs. I'm a nurse who works overnight on a psychiatric unit. The overnight schedule really messes up with my sleeping and eating habits.
I tried this biking deal about 6 years ago, bought some sort of mountain bike from an acquaintance from church. I tried riding to the mall one day, only 1/2 mile away. Couldn't do it. I tried one other time, couldn't do it. So I gave up.
A few weeks ago, on an unseasonably warm morning, I laid in bed alone while my wife was at work, and thought to myself... you know what, if I had a bike I would be out riding right now! I began looking around at bikes. I went to my local bike shop and rode a few there. I went to a sporting goods store and rode a few more there. Then I went to a local bike co-op type thing and rode a few more. In the end I ended up getting the first one I tried, the silver Electra Townie 21D. It was the only bike out of the dozen or so I tried that was comfortable.
This was about a week and a half ago or so. Because of work schedule, church commitments, being sick, weather, etc, I've only been on three rides. According to MapMyRide I've gone a total of 14.62 miles on the three rides. A huge improvement over not being able to get to the mall that long time ago!
