I bought a Townie for the flat foot concept, as I was new to bicycling (at 55 y/o) and feared falling. After a month and 50 miles I find myself raising the seat more and more. Still can touch the ground with both feet, although not flat, just the balls and toes of the feet. The only problem I have is that mine is a three speed and I still do not have the endurance to go above 15 miles and hour for an extended time. Would a more "normal" design bicycle be faster. I am riding on flat paved roads, very few cars.
