Thanks for all the responses. If I could travel with the bikes in the RV I would, they would certainly stay cleaner. But since they're outside, I thought that aluminum might be a better frame choice. And I guess I was looking to spend a little less, plus the Swift seems to have an ardent following. It's good to hear that the 1.75 Kendas have been adequate tires for most surfaces. As to non-folder large wheels, I suppose that makes sense, but having ridden my BF for the last 2 years, I've come to really enjoy the smaller wheeled ride. And of course, logic can only go so far when choosing a bike
