I bike regularly and trust me, these sorts of things vary a good deal between people. In my overly warm 70F office I feel like I need a shower halfway through the day anyway. There is no way in hell I'd bike for an hour or more before that. 45 minutes is my cutoff. And major cities are major outliers in cycle commuting.
