Ride consistently...at least several days per week
Eat a healthy diet...
A ss pain will diminish but a good saddle and padded bike shorts helps.
You are suspending all your weight on a very small area of your body...it's gonna hurt for a bit but will diminish over time.
Don't give up...it took a lot of time to get where you are now and it's going to take a lot of time to get where you want to be...take it one day at a time and enjoy the ride...you will live a longer, healthier and more enjoyable life.
Keep a gallon jug of water handy...every time you see a 9ish pound weight loss pick up the jug of water and imagine not carrying that around with you anymore...it's a simple trick that works...
