Recalling my old Fat tired Schwinn with the Knee action and two nice springs under the saddle, I'm wondering about some things. I'm weighing in at 240 these days. That 145 stuff dissapeared on me. So should I be looking for another of those smooth riding bueaties? Fat tires would be good, or am I thinking wrong. I think I'd like Road Tire Tread as well. I see a lot of Mountain bike tires with knobby tread on some of the Motorized bikes. Why's that? Style? Four strokes Shak a bit. Two strokes are 'nasty' to fuel. What forum would I go to see what some folks who've made long MB trips have to say?
