If you start with one fully frozen, you will likely have cold water to drink for at least the first hour on the bike, maybe longer. And should it remain frozen too long, freeze a bottle that is not entirely full. Then add some of the warmer water from your other water bottle to melt the ice as you ride.
On one of my touring trips I carried a water filter system (Brita) on my backpack. The ambient temperature was about 30°C. Yet the water is cool enough that the outside of the jug was wet - probably spillage of water, but could be condesation as well. That's something interesting to note...
But telling me 30°C is too hot is like telling a Norwegian -10°C is too cold. It just takes some time to get used to... Wear light clothing, very breatheable kinds. I wear football (soccer) jerseys, which I find more comfortable. You'll get ventilated by the air you go through most of the journey, but you only get drenched when you stop. Pouring water on your face is the best cure (photographers might want you to repeat), if you have water to spare
