Love the bike! You are going to have soooo much fun on that. Way better than exercising to videotapes inside. I've always had the "weight" thing going on. I lost 56 pounds about 8 years ago and have managed to keep that off. I'd still like to lose 20 more, so count me in! I did a 15 mile ride on gravel roads yesterday, probably 30 miles if you count the unexpected hills. (One of my students drew the route, but forgot to tell me about the hills, I let him know about it today...he just laughed) Anyway, I felt great afterwards. (Notice I said "after" not during...) And you know what the great thing about biking is? You can't quit! After I had ridden out about 8 miles, I KNEW I had to ride back, or call someone to come get me, and THAT wasn't happening!
