As Blueberry said, this is going to differ from person to person, and for me at least, my HR gets higher in colder temps.

The highest I can seem to get it in spinning class is 154 or so, and I have to be putting in 100% effort at a high resistance to get it that high. My heart rate recovers very fast, so I've a hard time keeping it in my desired zone during class.

On the road it will get in the high 150, lower 160s when climbing and that is pushing hard. Mountain biking it gets higher, so far the highs have been in the upper 160s though I suspect that will get higher as I get into more challenging terrain. Average HR is higher on the mountain bike than either road or spinning class.
