I once rode to work in 18F (-8C) temperatures. Not fun.
Now that I'm retired the coldest I want to ride in is high 30s. That's with lots of sun and little to no wind.
On a related note, I've found that my average speed decreases (on either bike) once the temps get cold enough for knee or leg warmers and full finger gloves. It really slows when I add a vest or jacket. Seems my muscles are rebelling against the idea of being out in the cool/cold.
