Cold water feels better but your body can't do anything with it until it heats it up to your body temp for absorbtion. That's why if you chug cold water, you can feel it sloshing around inside your gut. If it's warmer, it is absorbed faster and you don't get that affect.
I've read many debates about the temperature of water for faster absorbtion and don't care to get into a debate today...just stating the "facts" which I believe from the experiences I have had.
I would agree that warm water absorbs faster from both reading about the studies and similar experiences to what you describe, but people shouldn't be chugging while biking (or exercising in general.) Having all that fluid in your stomach isn't a good idea.
I do like cold water for it's cooling properties when it's really hot and humid out. When I lived/worked/played in the desert, I didn't mind warm water/sports drink. My sweat evaporated fairly quickly and keep me cool(ish.) When it's muggy out, it doesn't evaporate as quickly and I like the extra bit of cooling the cold water provides.
