It is 35 miles one way. The reason I was looking at a comfort bike is that I know there is one road in particular that the pavement is pretty bumpy and figured it would be too much for a road bike. If that's not the case, I would definitely consider that option. The particular "comfort bikes" I listed actually look more like hybrids than cruisers. So, other than "don't buy any of those bikes", if I had to choose, which is the best of the worst?
And, I do enjoy biking...although I haven't biked much since I was young. Other than swimming, this would be my next choice for exercise.
