One suggestion would have to do with intensity of the ride. According to what I've read maximum fat burning during exercise occurs at low intensity. What defines intensity? Heart rate zones, power output and other somewhat expensive to measure stuff. But an approximation would be:

Define you Heart Rate Max by multiplying your age by 0.7 and subtract that number from 208 (University of Colorado in Boulder, supposedly more accurate than the old 220- your age formula, although for me the numbers come out the same at 40 years old.)

74% of your MHR is "fatmax" with the approximate zone being from 68 to 79% MHR.

At that level fat provides about 50% of the calories you need to keep going for the first hour or so. Around 70% of the total energy after two hours, and 80% or more if your work duration exceeds three hours. If you increase the intensity then the Fat contribution decreases to 0 at 84%MHR.

Now all you have to do is keep your pulse rate there. For me that's about 133. I might point out that I don't usually have 3 hours to ride... but the same folks who supply all this point out that you burn more calories at higher intensity workouts so that even if you are burning less fat, you can wind up burning the same amount of fat in less time with higher intensity workouts, but as a lesser percentage of calories consumed. In the end it seems that caloric deficit is the only long term way to lose weight/fat.

But I'm really hoping you come across something I haven't :)
