As for bringing your bike with you, it all depends on the carrier. For example, Virgin Atlantic allows you to bring a bike for free in addition to your regular baggage allowance. On the other hand, carriers like Delta charge upwards of $200 each way.
However, I don't remember the road from Cancun to Playa del Carmen being particularly bicycle friendly. And by road, I mean one singular road, as I believe there is only one direct road between the two cities. With that said, when I was there, I wasn't paying attention to how bicycle friendly the roads were, so take my recollection with a grain of salt.
