Generally, the less you weigh, the harder it is to lose weight. Going from 275 to 167 is like taking off a 108 pound backpack. Obviously you are using much less energy (calories) just to move your body from place to place. (There's another reason that people plateau, but I'm not going to mention it because it'll just start a flame war.)

This is not a low intensity pace for somebody at your fitness level or cycling experience level. It would probably burn more calories if you cut back on the intensity and doubled the duration--although this is a controversial issue.
Last night I rode for around 45 minutes very low intensity....actually it was only about 10.5 miles. Today I am going to try and shy away from eating more than I normally would, but eat foods that keep you full longer.
Mileage is irrelevant. The crucial factors are time and perceived exertion (or heart rate if you use a monitor).
Probably fluid balance, as others said. You shouldn't worry about short term gains, but you should be very aware of longer term trends of a week or more. I've had good success with this formula:
I still don't understand the 5lb gain in two days tho
"Weigh yourself on the scales. If you gained weight, eat a little less next week. Repeat on a weekly basis for the rest of your life."
