85° to just over 90°F is the temperature I enjoy riding the most. And we aren't going to have what others call ideal temps for more than a brief period. It's a given here in the south that you will get sweaty doing anything outside in the spring and summer. Riding hard and keeping the speed over 16 - 18 mph or better can keep one comfortably cool at even higher temperatures. My legs seem to gripe more and take longer to loosen up even at 70°F temperature ranges.
