Here's one of several sites that gives some great "readiness" checklists. I question whether your son is truly ready for success yet: http://www.parentingscience.com/toilet-training-readiness...
Lots of little boys, particularly, don't have all aspects of readiness and willingness in place until they are between 3.5 and 4.5.
You just can't push a river any faster than it can flow. Same with maturation of our kids. Actually, when I was a toddler, around the time the wheel was invented, it was the fashion to force kids to potty train by the age of two. Some children succeeded early, but others were in training for a year, or two. Moms who "failed" perceived themselves to be objects of public ridicule, so the social pressures to train early were intense. Some parents (like my mother) went so far as to give their toddlers daily enemas to conveniently control their bowel functions.
It's almost a standing "joke" in my generation that a surprising large percentage of us (several whom I know personally) have been psychologically scarred by being forced before they had the physical readiness or emotional maturity. I am glad you're not willing to punish your son for his refusal.
The GOOD news:
When he's ready, he will probably become enthusiastic about getting himself trained. If you don't give him any reasons to resist or dig in his heels (and he could experience the "reverse" bribing by rewarding other children for success as psychological pressure), at some point he will want to use the potty and get out of diapers, just as he wanted to learn to walk and talk when he was ready.

So, yes, you can back off completely, and he WILL train, possibly sooner than if you push. But some parents also have really good experiences with light-hearted pre-training, some of which you've already done: reading stories about using the potty, watching videos, having potty-parties with your son's favorite toys "going potty," allowing him to watch how you and daddy use the potty, letting him flush, getting those big-boy pants ready, etc.
Some moms find rewards helpful, but I doubt that they'll really help if the child's bladder and nervous system, and emotional maturity, is just not there yet.
And as S H. notes, pee training generally happens first. Night training can follow by a few years in some children, and they can't help that. Poop training may also be a separate, and often later, step for many kids.
