Bodybuilding clashes with aerobic exercise.
You need some, of course, but for adding mass you need to
follow a bodybuilding regime. That includes a lot of rest so
the muscles can grow.
My 2 cents.... do what you want to do. You want to be a gym rat, that's
great, I love a good gym. You want to focus on cycling, good on ya...
You can even do both, but don't expect to look like Arnold cycling every day.
Here's a basic program, upper body, cycling medium (speed and distance), lower body, day off, intervals or distance (alternate),
day off.
