Keep riding. You may or may not see weight loss, but take a tape to yourself, your middle, your thighs, your calves, your arms, your neck..... you will lose mass.
Remember you didn't get in the shape we (yes I am including myself in this as I am now down to 362 pounds at 6'3") didn't get this way over night, and we aren't going to change ourselves back to where we want to be overnight either.
Keep at it, you will get there.
