This is what I’ve been trying to do and it has been working as long as I don’t blow it up on the weekends when I’m hanging out with my kids or friends.
I use Lose it to track everything and I settled on 2100 as my goal with the idea that my actual BMR is close to 2600. I will generally eat back about half of the calories from my 5-6 rides with the thought that approximately half of the calories are from my fat stores and don’t need to be replaced.
The more whole foods I eat the easier it is to keep the deficit without being hungry, I also try to get at least 100g of protein and I’m about 87kg at the moment.
I am down a little over 15lbs since I started in January and I feel good during my workouts for the most part so other than my inconsistency it has been working.
