Dude not the smartest idea to start cycling when you don't have much experience under your belt.

Your body needs to get adjusted to training+ you don't have enough lifting experience. I will agree with lovbyts , you should train atleast 3 more years consistent before even considerng cycling again.

Just wait , unless you want to harm yourself more. Just keep researching meanwhile , keep training , dieting and learning more.

Good luck to you!
