I've owned my Marlin 6 for two weeks now. I have diligently managed to get some seat time
every day, even if only 30 minutes... though some days have been 2+ hours. When I ride, I try to moderately exert myself--fast enough to get my heart rate up a bit, but not any sort of "race pace" or anything silly like that.
Since it has been two full weeks, this morning I decided to step on my bathroom scale. I'm down 4 pounds from when I first bought the bike.
I've heard it said that a safe/healthy rate of weight loss is 2-3 pounds per week. Using that as a guide, my short-term goal is to drop another 9 pounds by June 1st. I'll keep riding every day and see how it goes.
