Iím a person being 6í1 tall with the weight of 330 pounds. I use to be 385 and have gone on a diet to lose the extra weight I donít need. I use to ride a bike and I only weigh 185 pounds. I may never get back down to that weight again but if I can even get closer to that weight from where Iím at now will be a plus. Also thinking that riding a bike is both low impact and fun at the same time. That would put me into the Clydesdale section. Right now I'm trying to decide on what type of bike and brand to get. I want to ride the bike on pavement to lose some of this weight and endurance. After I use to riding and I have trimmed down I would like to take it on trails in the back woods here in Florida and Wyoming for some of the Mountain Trails there. Anybody been on the Medicine Bow Mountain Trail in Wyoming? Anyway the brands I'm thinking of in Mountain Bikes are the Specialized P1 all mountain bike or the Trek Mountain Hardtail or the Trek Mountain Full-Suspension.
